Latest Extraterrestrial life Stories
GREENBELT, Md., May 26 /PRNewswire-USNewswire/ -- NASA-sponsored scientists looking back at Earth with the Deep Impact/EPOXI mission have developed a method to indicate whether Earth-like alien (extrasolar) worlds have oceans.
Since the early 1990s astronomers have discovered more than 300 planets orbiting stars other than our sun, nearly all of them gas giants like Jupiter.
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.
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.
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.
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
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.
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.

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...
