Scientists could learn about Martian water life by plumbing a spring in an iron ore mine in Minnesota's Iron Range, University of Minnesota researchers say. The researchers say microorganisms in the lowest levels of the spring could be a boon for scientists interested in studying possible life on Mars, the St. Paul Pioneer Press reported Monday, because the mine water was held by rock formed 2.7 billion years ago when water was plentiful but oxygen wasn't. Scientists said they found...

As scientists search for life on Mars, they should take a close look at rock varnish, according to a paper in the current issue of the "Journal of Geophysical Research." The paper describes how a research team led by Kimberly R. Kuhlman, of the Tucson-based Planetary Science Institute, found bacteria associated with rock varnish in an area where the surrounding soils were essentially devoid of life. The study suggests that rock varnish could provide a niche habitat for microbial life on Mars...

Scientists are expanding the search for extraterrestrial life -- and they've set their sights on some very unearthly planets. Cold "Super-Earths" -- giant, "snowball" planets that astronomers have spied on the outskirts of faraway solar systems -- could potentially support some kind of life, they have found. Such planets are plentiful; experts estimate that one-third of all solar systems contain super-Earths. "We know there are a lot of super-Earths out there, and the next generation of...

The U.S. space agency says its Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. The National Aeronautics and Space Administration said the discovery is an important step toward finding chemical biotracers of extraterrestrial life. Although the extrasolar, Jupiter-sized planet called HD 189733b is too hot for life, NASA said the Hubble observations are a proof-of-concept demonstration that the basic chemistry for life can be measured on...

An organic sugar molecule that is directly linked to the origin of life has been located in a relatively hospitable part of the galaxy, scientists said. Glyceraldehyde is a molecule with significant ties to the origins of life, as it can react to form ribose, a key constituent of the nucleic acid RNA. "This is an important discovery as it is the first time glycolaldehyde, a basic sugar, has been detected towards a star-forming region where planets that could potentially harbor life may...

Minuscule traces of cells can be detected in a mineral likely present on Mars, a new study shows. The results, obtained using a technique developed at the U.S. Department of Energy's Idaho National Laboratory, could help mission scientists choose Martian surface samples with the most promise for yielding signs of life. INL's instrument blasts off tiny bits of mineral and looks for chemical signatures of molecules commonly found in cells. While other methods require extensive sample handling,...

Tidal heating can cook some planets, thaw others, and drive plate tectonics needed for life. Astronomers searching for rocky planets that could support life in other solar systems should look outside, as well as within, the so-called "habitable zone," University of Arizona planetary scientists say. Planets too close to their stars are roasted. Planets too far from their stars are frozen. In between, research models show, there's a habitable zone where planet temperatures approximate Earth's....

More than 500 images, text messages and drawings were transmitted to a planet 20 light years away from Earth on Thursday by a massive radar telescope in the Ukraine that normally tracks asteroids. The recipient planet, known as Gliese 581C, was selected because scientists believe it is capable of supporting life.  However, any reply to the messages would not return to Earth for 40 years.  The effort is part of a competition known as "A Message From Earth" that is being sponsored...

The National Aeronautics and Space Administration has picked 10 U.S. teams to study the origins, evolution, distribution and future of life in the universe. Each interdisciplinary team receives a five-year grant averaging $7 million and becomes a member of NASA's Astrobiology Institute, located at NASA's Ames Research Center. Selected are teams from the University of Hawaii, Arizona State University, the Carnegie Institution of Washington, Pennsylvania State University, the Georgia...

NASA has awarded five-year grants, averaging $7 million each, to 10 research teams from across the country to study the origins, evolution, distribution, and future of life in the universe. The interdisciplinary teams will become new members of the NASA Astrobiology Institute, located at NASA's Ames Research Center at Moffett Field, Calif. Teams from the University of Hawaii in Honolulu; Arizona State University in Tempe; the Carnegie Institution of Washington; Pennsylvania State University...

Reptilians
2013-09-05 08:02:45

Reptilians are depicted as reptile humanoid creatures that are used in science fiction, ufology, and in conspiracy theories. Sometimes reptilians are also called reptoids, reptiloids, or draconians. One of the first alleged contacts with a reptilian occurred in 1967 in Ashland, Nebraska. Police officer Herbert Schirmer claimed to have been abducted and taken aboard a UFO by reptile-like humanoids that had a winged serpent emblem on the left side of their chests. David Icke, a British...

Flatwoods monster
2013-08-26 08:20:20

The Flatwoods monster is claimed to be an unidentified species of either a terrestrial cryptid or an extraterrestrial being. It was reported being seen in the town of Flatwoods, West Virginia, on September 12, 1952 on some land owned by a local farmer, G. Bailey Fisher. The witnesses include two brothers, Edward and Fred May, their mother Kathleen, a friend of the boys, Tommy Hyer, along with Neil Nunley, Ronnie Shaver, and national guardsman Eugene Lemon. It was described as being ten...

Sagan, Carl
2004-10-19 04:45:44

Carl Edward Sagan (November 9, 1934 - December 20, 1996) was an American astronomer who pioneered exobiology and promoted the Search for Extraterrestrial Intelligence (SETI) and science in general. He is less well known for his skepticism. Born in Brooklyn, New York, Sagan attended the University of Chicago, where he received a bachelor's degree (1955) and a master's degree (1956) in physics, before earning his doctorate (1960) in astronomy and astrophysics. He taught at Harvard University...

Xenobiology -- Xenobiology (or exobiology, or astrobiology) is the term for a speculative field within biology which considers the possibility of, and possible nature of, extraterrestrial life. It also necessarily includes the concept of artificial life, since any life form might naturally evolve elsewhere, could conceivably come out of a laboratory using a future technology. It might be difficult to tell whether a truly strange life form had in fact arisen in space, or was designed much...
