WASHINGTON, May 20 /PRNewswire-USNewswire/ -- A NASA-funded study indicates that an intense asteroid bombardment nearly 4 billion years ago may not have sterilized the early Earth as completely as previously thought. The asteroids, some the size of Kansas, possibly even provided a boost for early life. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The study focused on a particularly cataclysmic occurrence known as the Late Heavy Bombardment, or LHB. This event occurred...

Questions such as "How to search for weird alien life?" and "Would Earth microbes survive if delivered to the surface of Mars?" are addressed in articles that are part of the collection of reports presented in the current issue of Astrobiology. David Smith, Andrew Schuerger, Mark Davidson, Stephen Pacala, Corien Bakermans, and Tullis Onstott, from Princeton University, the Kennedy Space Center, and Michigan State University, exposed a bacterium that lives in the Siberian permafrost on Earth...

Solar energy and winds, collisions with asteroids and comets, and changing magnetic fields have all altered the environment of Mars, a planet that may have been able to support life during its history, as documented in a special collection of papers published in the current issue of Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. Compiled by Helmut Lammer, PhD, Senior Editor of Astrobiology, from the Austrian Academy of Sciences, this special paper collection...

Planets near stars cooler than Earth's sun may lack the material to produce life, say scientists at Johns Hopkins University in Baltimore. The scientists used the infrared Spitzer Space Telescope to search for hydrogen cyanide around 61 young stars, hydrogen cyanide being a component of a compound in DNA found in every living thing on Earth, the Los Angeles Times reported Saturday. The researchers found hydrogen cyanide in 30 percent of the yellow, sun-like stars, but none around cooler,...

HAMPTON, Va., April 2 /PRNewswire-USNewswire/ -- NASA scientist Michael Mumma and his team of researchers have discovered methane on Mars, indicating the planet is still alive -- either in a biologic or geologic sense. "The big question is, 'What is the origin of this methane now being released,'" Mumma says. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) While living systems produce more than 90 percent of Earth's atmospheric methane, other purely geological processes,...

GREENBELT, Md., March 17 /PRNewswire-USNewswire/ -- NASA scientists analyzing the dust of meteorites have discovered new clues to a long-standing mystery about how life works on its most basic, molecular level. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) "We found more support for the idea that biological molecules, like amino acids, created in space and brought to Earth by meteorite impacts help explain why life is left-handed," said Dr. Daniel Glavin of NASA's Goddard...

NASA scientists analyzing the dust of meteorites have discovered new clues to a long-standing mystery about how life works on its most basic, molecular level. "We found more support for the idea that biological molecules, like amino acids, created in space and brought to Earth by meteorite impacts help explain why life is left-handed," said Dr. Daniel Glavin of NASA's Goddard Space Flight Center in Greenbelt, Md. "By that I mean why all known life uses only left-handed versions of amino acids...

When NASA's Kepler telescope rockets into the night sky on Friday, March 6, from Cape Canaveral Air Force Station in Florida, two University of California, Berkeley, astronomers - key members of the Kepler team - will be watching its fading contrail, hoping that the telescope will reveal Earth's and humanity's place in the universe. Kepler's main goal is to discover Earth-size planets outside our solar system with conditions conducive to life, but it also will tell us how common rocky planets...

Data from the Mars Reconnaissance Orbiter (MRO) suggest the discovery of ancient springs in the Vernal Crater, sites where life forms may have evolved on Mars, according to a report in Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. Hot springs have great astrobiological significance, as the closest relatives of many of the most ancient organisms on Earth can thrive in and around hydrothermal springs. If life forms have ever been present on Mars, hot spring deposits...

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...

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...
