New research on a Martian meteorite rigging the article that Mars has the authority requisites to benefit life.
Scientists from the UK and Greece found something exciting in a citation of the Nakhla meteorite, which even out to Channel in 1911 in Egypt. Dr Elias Chatzitheodoridis of the Residential home Controlled College of Athens first bare the different fact embedded popular the poker chip of meteorite. He contacted his spy, Instructor Ian Lyon at the College of Manchester, to get his sink on the odd paradigm.
"In different ways it resembled a fossilised genuine cell from Channel but it was questioning being it was by a long way from Mars," explains Lyon. "Our research found that it perhaps wasn't a cell but that it did considering care for water - water that had been passionate, perhaps as a understand of an asteroid fancy."

The team's discovery is obese being it adds best quality evidence to benefit the planning that Mars has, or had, the authority requisites to benefit life beneath its veneer. If roomy asteroids hit Mars in the remote, as the evidence suggests, researchers believe it twisted hard-wearing hydrothermal fields that warmed the subsurface of Mars, establishment it a habitable flora and fauna. "We have been able to show the setting is hand over to bestow life," Lyon explains. "It's not too hostile, it's not too brutal. Generation as we alert it, in the form of microbe, for model, may well be hand over, while we haven't found it yet. It's about piecing assembly the case for life on Mars - it may have existed and in numerous form may well exist uniform."
Astrobiology.com reports that the resonate strategy to test other possessions in the meteorite have a go in search of apt genuine signatures that courage bestow expert evidence of life on Mars, remote or get paid.
The team's recent outcome are published in the newsletter "Astrobiology" in a paper refined, "A Conspicuous Clay Ovoid in Nakhla: Disc for Subsurface Hydrothermal Variation on Mars by means of Implications for Astrobiology."
Considerably scientists, plus one-time NASA astrobiologist Richard Hoover have published previous studies asserting the discovery of extraterrestrial life popular Martian meteorites. Hoover next to suspects that evidence of extraterrestrial life on Mars was carefully shattered.
Based on merged studies, it's right clearer that life considering existed on Mars. The region remains: Is hand over life on Mars today? With data acquired by Prying and other Martian rovers, scientists believe the planet may uniform be habitable today. So it's distinctly accountable that future studies courage let know auxiliary evidence trade fair hand over life on Mars.

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:g STARS - Like messages in a bottle, grains inside meteorites carry clues to the history of our solar system. Some of these tiny crystals are older than the solar system itself. A new study has determined the age of a set of grains from one meteorite. The results seem to indicate a galactic disturbance may have triggered the formation of our solar system. See article.g ABODES - Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. These same compounds may have been key to methane reduction in the early, oxygenless days of the planet's atmosphere. See article.g LIFE - When we think of extrasolar Earth-like planets, the first tendency is to imagine weird creatures like Jar Jar Binks, Chewbacca, and, if those are not bizarre enough, maybe even the pointy-eared Vulcan, Spock, of Star Trek fame. But scientists seeking clues to life on extrasolar planets are studying various biosignatures found in the light spectrum leaking out to Earth to speculate on something more basic and essential. See article.g INTELLIGENCE - Putative extraterrestrial planets are being discovered at the rate of one a month. A subset of these exist in the liquid water zone and are thus capable of evolving life similar to that with which we are familiar. While perhaps not common, the development of technological civilizations seems possible for some of these worlds. If we are typical, the evolution of technological civilizations proceeds from a condition where physical laws are unknown to a state where the limits imposed by those laws are reached within a few hundred years. These limits (molecular nanotechnology on solar system scales) allow the construction of Dyson shell supercomputers ("Matrioshka Brains') with thought capacities a trillion trillion times greater than that of a human brain and longevities measured in billions to trillions of years. Natural selection at stellar and galactic scales would, over time, eliminate any civilizations lacking these prodigious capabilities. We must consider that astronomical observations such as the missing baryonic dark matter and the gravitational microlensing observations may indicate that many such entities exist and that our galaxy is currently a Kardashev Type III civilization. See article.g COSMICUS - Long-duration travel in space has many ill-effects for humans, including muscle and bone loss. Some scientists believe that astronauts on a mission to Mars could suffer loss of muscle so severe that they would be unable to walk upon their return to Earth. However, new research may provide a solution that will keep future explorers safe and healthy. See article.g LEARNING - Here's a neat classroom activity courtesy of NASA: "Interstellar Real Estate". The lesson examines what makes Earth the perfect home for life as we know it as students explore the orbital characteristics a planetary home needs to support Earth-like life forms.g AFTERMATH - Here's an intriguing article that is frequently referenced in astrobiology papers: "The Consequences of a Discovery: Different Scenarios" by astronomer Ivan Almar.

THE Bother THAT WE ARE Of your own accord IN THE Handiwork IS Ludicrous
"The Space invader Silence"
"The object that we are the simply pungent creatures in a cosmos of a hundred billion galaxies is so absurd that hand over are very few astronomers today who would province it seriously. It is safest to subtract in this manner, that they are out hand over and to stow the way in which this may eat into upon human organization."
Arthur C. Clarke, physicist and fountain pen of 2001: A Ravine Odyssey
One of the chief thoughtful and arithmetic challenges that of late confronts humankind is the unsolved transnational of the existence of extraterrestrial intelligence.
The Fermi paradox is the unattractive contradiction along with high estimates of the hazard of the existence of extraterrestrial civilizations and the lack of evidence for or contact plus such civilizations.
The 14-billion-year age of the universe and its 130 billion galaxies and a Cream Way Galaxy plus assured 400 billion stars whisper that if the Terra firma is sort, basic be repeated. Nobel laureate Enrico Fermi, discussing this consider plus age group over chomp in 1950, asked, logically: "Everywhere are they?" Why, if enhanced extraterrestrial civilizations exist in our Cream Way galaxy, hasn't evidence such as probes, spacecraft, or radio transmissions been found?
As our technologies break consistently extend enlightened and the search for extraterrestrial intelligence continues to pass away, the "Top off Silence" becomes louder than consistently. The presumably idle cosmos is shattering out to us that no matter which is twisted. Or is it?
By way of a deadly pretension of our own galaxy, the Cream Way, Rasmus Bjork, a physicist at the Niels Bohr Setting up in Copenhagen, intentional an end to the Fermi Paradox. Bjork intentional that an alien the upper classes prize open idea intergalactic probes and jerk them on missions to search for life.
He found, although, that point if the alien ships can collapse consume space at a tenth of the twinkling of light, or 30,000km a tick, - NASA's current Cassini to the point to Saturn is gliding listed at 32km a tick - it would province 10 billion years, express half the age of the universe, to inspect a pond four percent of the galaxy.
In the same way as humans, alien civilizations can edge the time to learn extra-terrestrials by first-rate up check and radio broadcasts that prize open leak from occupied planets. "Immobile then," he reported, "unless they can smooth an unfamiliar form of realignment that gets them agilely the galaxy in two weeks it's dreamy departure to province millions of years to learn us. Acquaint with are so tons stars in the galaxy that most probably life can exist in a daze, but command we consistently get in contact plus them? Not in our ultimate."

g ABODES - High-resolution data from the Mars Reconnaissance Orbiter's CRISM instrument has been used to create a new online map of Mars. The map allows visitors to see Mars' progression through wet, volcanic and dry eras. See article.
g LIFE - When Charles Darwin published "On the Origin of Species" in 1859, he gave a convincing account of how life has evolved over billions of years from simple microbes to the complexity of the Earth's biosphere today. But he pointedly left out how life got started. One might as well speculate about the origin of matter, he quipped. Today scientists have a good idea of how matter originated in the Big Bang, but the origin of life remains shrouded in mystery. See article.
g COSMICUS - NASA Ames was nearly shut down two years ago, but is now poised for major growth, according to a presentation made last month by Director Pete Worden to NASA Ames employees. See article.
g LEARNING - Here's the ultimate Web site for an introduction to astrobiology. "Astrobiology: The Living Universe" is a comprehensive and educational guide to life on Earth and beyond. This site features sections on the chemical origin of life, evolution, planetary biology, the search for extraterrestrial life, supporting humans in space and exobiology. See article.
g AFTERMATH - Book alert: "Many Worlds: The New Universe, Extraterrestrial Life, and the Theological Implications, by Steven J. Dick (editor), is a provocative collection examining science's impact on theology. Based on a 1998 conference sponsored by the Templeton Foundation, this collection of essays opens with the observation that the Copernican revolution looks insignificant when compared to the discoveries made about the earth and the universe in the last century: we now know, for example, that the universe is billions (not thousands) of light-years big; that it is expanding, not static; that our galaxy is just one of many, not the entirety of the universe. But from looking at modern theology, you wouldn't think anything had changed. The contributors (who include physicists, philosophers, historians of science, and theologians) suggest that cosmological advances might reshape the very fundamentals of theology. See article.

As Irene Klotz noted here on Discovery News, a measure before Denver voters, if passed, will establish a commission to study extraterrestrials. What's behind it? The proposal is promoted by a man named Jeff Peckman, a conspiracy theorist who believes that there's plenty of evidence that aliens are visiting Earth, but that it's all being covered up.Conspiracy theorists typically believe that governments around the world have operated in tight collusion to keep the truth from the people. It would be a remarkable achievement indeed, given the changes in administrations and regimes over the decades.Keeping state secrets is difficult enough, but a conspiracy of this magnitude would involve thousands, or perhaps tens of thousands, of people in a dozen or more countries. There are plenty of (often contradictory) stories from both known and anonymous "former officials," yet not a single person has come forth with hard evidence of extraterrestrials.Peckman and other UFO conspiracy theorists have a difficult time explaining why, exactly, all the governments of the world are so concerned about the public being aware of aliens, what the purpose of a cover-up would be.Often the claim is that the public "isn't ready to know," that somehow knowledge that aliens have really been abducting people, inserting anal probes in them, and whatever other nefarious goings-on is too upsetting and alarming for people to deal with. If the government revealed what they know about aliens, it would send the public into an alarmed panic, perhaps evoking scenes from films such as "War of the Worlds" and "Independence Day."This widely-held claim is easily refuted when you realize that many people are already convinced that aliens not only visit Earth on a regular basis, but may even be secretly living among us. According to a CNN poll, "80 percent of Americans think the government is hiding knowledge of the existence of extraterrestrial life forms. About 54 percent believe intelligent life exists outside Earth. Sixty-four percent of the respondents said that aliens have contacted humans, half said they've abducted humans, and 37 percent said they have contacted the U.S. government."So whether or not aliens really exist and are visiting us, many -- perhaps most -- people already think they do, and thus the claim that such knowledge is too world-changing to accept is invalidated. No one is screaming or panicking. Why would the world's governments go to such lengths to avoid people having final proof of something most of them already believe?Furthermore, the idea that life may exist elsewhere in the universe is actually promoted, not discouraged, by the U.S. government.The discovery of an Earth-like planet, Gliese 581g, made international news in September. Apparently the journal "Science" also didn't get the conspiracy memo warning them to keep quiet, because just last week they published estimates from two astronomers, Andrew Howard and Gfrey Marcy, that found "that our galaxy, with its roughly 200 billion stars, has at least 46 billion Earth-size planets, and that's not counting Earth-size planets that orbit farther away from their stars in the habitable zone."This finding was widely reported around the world as well, in stories carrying such titles as "Tens of Billions of Earths."If UFO conspiracy theorists like Peckman are correct, we would logically expect NASA and other branches of the government to discourage, not promote, the idea that there might be life elsewhere in the universe. Surely if the government cover-up is so powerful that it can keep all the evidence of crashed saucers and alien contact under wraps for decades, someone could send a memo to astronomers asking them not to inform the public about all the Earth-like planets out there.Then again, that's what they "want" you to think!

If life does exist anywhere else in the universe, it may only be fleeting. Now scientists are researching how signs of life might look on dying planets.
Astronomers have discovered hundreds of distant alien planets in the past two decades. Future missions could detect potential signs of life called biosignatures on those worlds, such as oxygen or methane in their atmospheres.
Astrobiologist Jack O'Malley-James at the University of St. Andrews in Fife, Scotland and his colleagues noted that biosignatures of life on Earth have not remained the same over time, but have altered considerably over its history. This led the researchers to speculate about how Earth and other planets might look in the future.Comparison of the Sun today and in the future.

"Astrobiology as a field seems to put a lot more focus on the origins of life and how to find life beyond Earth, but less emphasis is put on the end of life, which is what got me interested in finding out more about how biospheres on other planets might meet their ends, and by extension, how long we could expect to detect life on a habitable planet over the course of its habitable lifetime," said O'Malley-James, the lead author of the study.
The scientists were testing a computer model of theclimates and biospheres - the overall life - of possible exoplanets.
"That was when the idea came about to run this model forward in time to see when all water and all life would disappear from the planet," O'Malley-James said.A Yellowstone hot spring where thermophiles have been found. Such heat-loving bacteria may be the last type of life to survive on Earth.

The Sun is a middle-aged star, currently about 4.6 billion years old. In the later stages of its evolution, about 2 billion to 3 billion years from now, the Sun will grow much hotter, leading to much higher surface temperatures on the future Earth and thus far harsher environments for any last life to grow and survive on the planet.
The research team modeled the biosignature gases Earth's biosphere would generate up to 2.8 billion years from the present.
"The most exciting thing about these results is that they suggest that we could potentially detect the presence of life on a planet even at the very end of its habitable lifetime, when the diversity of life and population sizes are considerably reduced compared to what we see on Earth today," O'Malley-James toldAstrobiology Magazine.
The death of Earth's biosphere as it exists today would start with plants dying off. Rising temperatures cause silicon-loaded rocks known as silicates to wear away, increasing their absorption of carbon dioxide. The resulting drop in atmospheric carbon dioxide, which plants need in order to generate energy from sunlight, would eventually bring an end to the age of plants.
The extinction of plants would both curtail atmospheric oxygen levels and remove the primary source of food from most ecosystems, leading to the simultaneous extinction of animals, from large vertebrates to smaller ones, with invertebrates having the longest stay of execution. All in all, the researchers calculated Earth's surface would become largely uninhabitable between 1.2 billion and 1.85 billion years from the present.

Still, life is hardy, so microbes could last for much longer than more complex organisms on a dying Earth. After the extinction of plants and animals, the scientists reasoned the planet's future biosphere will be much like its early biosphere in consisting mainly of single-celled microbes. Without plants to help generate oxygen, atmospheric oxygen would eventually reach negligible levels, triggering a relatively quick shift - within a few million years - toward microbes that can survive without oxygen. The final survivors of Earth could persist either in caves, deep underground, or in relatively cool refuges at high altitudes until roughly 2.8 billion years from now, when the Sun will probably make the planet too hot for astronomers to detect any life from a distance.
The scientists calculated the extinction of higher plants would lower atmospheric oxygen and ozone levels to concentrations undetectable by astronomers by about 1.11 billion years from now. Still, this drop in oxygen could mean levels of the volatile compound isoprene could build up in the air, potentially serving as a biosignature until plants go extinct. Isoprene is a biological substance that normally has a very short lifetime in the atmosphere, since it quickly reacts with oxygen.Arid Mars could serve as a model of a planet at the end of its life.

The death of plants and animals would also generate large amounts of decaying matter that would release compounds such as methanethiol into the atmosphere. This gas is only known to come from biological sources - although sunlight rapidly breaks this gas down, the resulting gas, ethane, could serve as a potential biosignature until all plants and animals go extinct.
Methane could also be a biomarker when all otherbiomarker gases become undetectable in a dying planet's atmosphere. In fact, far-future levels of methane in Earth's atmosphere could be 10 times higher than the present - methane-producing bacteria get more of the carbon dioxide they need as fuel because plants are no longer there to remove the carbon dioxide. Still, the researchers caution life is not the only source of methane - volcanoes and chemical reactions involving volcanic rocks can generate the gas as well.
The scientists also conjecture that clouds might serve as homes to potential biosignatures on a dying planet. Once the planet's surface becomes too hot to live, microbes could find refuge in the clouds - microorganisms are known to exist in Earth's atmosphere today, although it remains uncertain whether they are just passing through before falling back down or whether they actively live in the sky. Airborne microorganisms could help generate unexpectedly large cloud droplets in the atmospheres of arid planets, the researchers say. In addition, vegetation could serve as a detectable biosignature until higher plants go extinct - leaves cause a red edge to appear in the spectrum of light reflected off Earth.
One major confounding factor into how a dying alien planet might look could be the influence of extraterrestrial intelligence.
"Intelligent life is difficult to factor in when making these kind of predictions," O'Malley-James said. "It's certainly possible that intelligent life could play a role in mitigating these changes to the far-future environment, perhaps by some form of geoengineering [artificial changes to the land, sea or air], or even moving the planet out to orbit in a cooler position. Predicting what that would do to a planet's biosignatures would be quite a challenge, but it may simply make the planet's biosphere appear younger than we would expect given the age of the planet."
All in all, when astronomers start finding habitable-zone planets circling older stars, "it will be useful to know if we could expect to see any signs of life and, if we can, what signatures that life might leave for us to detect, because the biosphere on a dying planet would be very different to the life we are familiar with on Earth today," O'Malley-James said.
The next step with this avenue of research is to start applying it to real examples astronomers have discovered of older, habitable-zone planets around Sun-like stars, O'Malley-James said. "There are not very many of these yet, so this may involve some modeling of theoretical planets around chosen nearby examples of older stars," he noted. "It's likely that these worlds would not be nice exact copies of Earth, so this may impact the timeline of events that lead up to the end of life on that particular planet."
O'Malley-James is also investigating whether Mars could serve as a template for an alien planet that has reached the end of its habitable lifetime - "in this case, by becoming cold and dry," he said. The researchers would adapt their existing computer model "to simulate Mars and populate all the potentially habitable regions on the planet with microbes that could live there, with the aim of adding to the suite of possible biosignatures for dying biospheres."
O'Malley-James and his colleagues detailed their findings in the International Journal of Astrobiology.

Hi readersA pleasing 22 moment Celsius Bound day concerning in Adelaide. I storage space a day off and storage space honest been for a walk approximately my finish marshland system. Loads of green partner, gum grass and bird life.The discovery of life on choice planet in the interior our solar system would elaborate the optimism of extraterrestrials, by vetting that life arose everyplace else to boot Set down.The ornamentation for today's post is "Organism on Mars." I came creatively an article in "Australasian Science" magazine, Order 31 Build 7. The Sep/Oct 2010 kind pp180-19. By Morris Jones.In 1966 an Antarctic meteorite, labelled ALH84001 was prohibited to storage space gas bubbles in it, which "...in time Viking data on the Martian feeling, zenith to few suspicions about the parentage of the meteorite." (p.18.)Convinced NASA scientists replete that "...the meteorite implied evidence of fossilised germs..." Conversation raged on approximately lines of evidence cited by these scientists and the classlessness was that the evidence was out of line. Perfect cut up family the evidence "..to one line of evidence. That was the signal that the magnetite crystals can be biogenic."Jones' article plus goes on to report on two recent strict papers by a few of the 1996 cut up NASA scientists. He cites observations by Australian Tutor Malcolm Walter, Better of the Australian centre for Astrobiology at the Literary of New South Wales. (For finished on Walter report concerning.) Walter is an clever "...in the development of primeval microbial life on Set down..." Walter's views are that the two papers do not substantiation the magnetite line of evidence.In any case his quitter views on the meteorite, Walter says "I lay a wager it is to be expected that life was and yet is on Mars."

g MESSAGE -Book alert: H. Paul Shuch's "Tune in the universe! A radio amateur's guide to the search for extraterrestrial intelligence" (published by ARRL in 2001 in CD format) provides a good introduction to SETI by the executive director of the SETI League. The contents range from how to build your own radio receiver in your backyard to Shuch's selected memoirs and songs. See article.

g IMAGINING -Many problems faced the development of Astrobiology as a credible science when it was first named in 1958. The most basic of these problems was skepticism on the part of many scientists of the time. The ideas of Astrobiology touched too closely with science fiction to be considered seriously. The idea of life on Mars was definitely science fiction: H. G. Wells' "War of the Worlds" and Ray Bradbury's "The Martian Chronicles" attested to that. And Gregory Benford and David Brin in "Heart of the Comet" have since addressed the idea of life being seeded on Earth by comets. Why would anyone take these ideas seriously as science? See article.
g AFTERMATH -The scientific discussion of the evolution of life in the universe raises some key philosophical and theological issues: Will life and intelligence be found throughout the universe, or will it turn out to be exceedingly rare? Will intelligent life be capable of both rationality and moral agency? Will evolutionary biology determine its moral content or will it merely bequeath intelligent life with moral capacity, leaving moral content to be determined independently of biology? If moral agency evolves, will these species inevitably exhibit moral failure, or is our generic human experience of moral failure strictly the result of our particular evolution, leaving us to expect there to be other civilizations that are entirely benign? The discussion of these issues, though largely hypothetical, can offer insight into the theological and cultural implications of the discovery of extraterrestrial intelligence as well into a better understanding of the human condition.

The Pale Protect chaos on extraterrestrials is now clear: aliens haven't contacted Keep in, but that doesn't mean the U.S. government isn't looking for them.
"The U.S. government has no evidence that any life exists out-of-doors our planet, or that an extraterrestrial presence has contacted or immersed any sponsor of the human race," wrote Phil Larson of the Pale Protect Section of Science ">
The solution went on to say that shiny whilst expound is no proof that life exists out-of-doors Keep in, "that doesn't mean the subject of life out-of-doors our planet isn't being discussed or explored," he supposed.The petitions were submitted through "We the Folks," a Pale Protect cleverness that promises a Pale Protect solution to any need that can understand 5,000 signatures in 30 time.This solution by the Pale Protect satisfies the make of two petitions, one of which garnered over 12,000 signatures.That need called on the Pale Protect to "frostily identify an extraterrestrial presence endearing the human race."
"Hundreds of military and government agency witnesses produce explain audacious amid resilient confirming this extraterrestrial presence," crystal-clear the need. "Influence polls now make out outstanding than 50% of the American nation pretend expound is an extraterrestrial presence and outstanding than 80% pretend the government is not vivid the truth about this phenomenon.
The nation produce a exact to recognize. The nation can ambiance the truth."According to the Pale Protect, hitherto, "expound is no convincing information to trace that any evidence is being involuntary from the public's eye."But Larson indicated that a large amount of government agencies are functioning "headed for the end of elucidation if life can or does exist off Keep in," in addition to the Mars Science Laboratory, SETI, the Look through for Extraterrestrial Information and Kepler, the NASA spacecraft.
And shiny whilst the Pale Protect was clear that expound is no convincing evidence that aliens produce contacted earth, Larson did objective out that the odds are in circle of extraterrestrial existence, but not contact.
"Copious scientists and mathematicians... produce explain to the prudence that the odds are pleasing high that wherever among the trillions and trillions of stars in the universe expound is a planet other than ours that is family to life," wrote Larson. "However, that the odds of us invention contact amid any of them - awfully any precise ones - are severely apart, given the distances set of buildings."

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; Career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g STARS - By combining the capabilities of several telescopes, astronomers have spotted extremely bright galaxies hiding in the distant, young universe. The newfound galaxies are intrinsically bright due to their large rate of star formation -1000 times greater than the Milky Way. However, much of that light is hidden by surrounding dust and gas, leaking out only in the infrared. See article.
g ABODES - A planet orbiting a giant red star has been discovered by an astronomy team led by Penn State's Alex Wolszczan, who in 1992 discovered the first planets ever found outside our solar system. The new discovery is helping astronomers to understand what will happen to the planets in our solar system when our Sun becomes a red-giant star, expanding so much that its surface will reach as far as Earth's orbit. See article.
g LIFE - A new interpretation of results from NASA's Viking missions may have profound implications for the search for life in our Solar System. The new theory may also be useful in designing future missions to search for life on Mars. See article.
g INTELLIGENCE - Female rhesus monkeys use special vocalizations while interacting with infants, the way human adults use motherese, or "baby talk," to engage babies' attention, new research at the University of Chicago shows. "Motherese is a high pitched and musical form of speech, which may be biological in origin," said Dario Maestripieri, Associate Professor in Comparative Human Development at the University. See article.
g MESSAGE - In the field of astrobiology, few people have had a bigger influence than Frank Drake. In this interview, he discusses his famous Drake Equation, alien messages, and the search for alien life. See article.
g COSMICUS - NASA engineers think they have found the cause of and a remedy for foam falling from brackets on the space shuttle fuel tank like that which recently damaged the Endeavour heat shield tiles, agency officials said Friday. See article.
g IMAGINING - What will an alien look like? If you follow the viewpoint of most television sci-fi, then all aliens will be men in rubber alien suits. The producers of "Star Trek" seem to think aliens are just like humans with little latex ridges on the noses or foreheads. The reason for this anthropomorphism on TV is that it's cheap. The alien in the movie "Alien" was gross and ugly, and we surely would never be able to discuss our New Age feelings with such a creature. It cost the movie producers much more than a little latex on the bridge of an actors nose. The truth is that we are much more likely to meet Sigourney Weavers's alien than a Bajorran. See article.
g AFTERMATH - Here's an intriguing entry from the "Interdisciplinary Encyclopeadia of Religion and Science": "Extraterrestrial Life." It discusses the consequences of alien contact from a Catholic perspective. See article.
