Alien Hunters Should Look For 'City Lights'
2011-11-04 03:42:51

In the search for extraterrestrial intelligence, astronomers have hunted for radio signals and ultra-short laser pulses. In a new paper, Avi Loeb (Harvard-Smithsonian Center for Astrophysics) and Edwin Turner (Princeton University) suggest a new technique for finding aliens: look for their city lights. "Looking for alien cities would be a long shot, but wouldn't require extra resources. And if we succeed, it would change our perception of our place in the universe," said Loeb. As with...

Scientists Find New Way To Determine When Water Was Present On Mars And Earth
2011-10-20 07:50:11

The discovery of the mineral jarosite in rocks analyzed by the Mars Rover, Opportunity, on the Martian surface had special meaning for a team of Syracuse University scientists who study the mineral here on Earth. Jarosite can only form in the presence of water. Its presence on Mars means that water had to exist at some point in the past. The trick is in figuring out if jarosite can be used as a proxy for determining when, and under what conditions, water was present on the planet. The SU...

Image 1 - Researchers Take Temperature Of Mars's Past
2011-10-13 04:19:02

Researchers at the California Institute of Technology (Caltech) have directly determined the surface temperature of early Mars for the first time, providing evidence that's consistent with a warmer and wetter Martian past. By analyzing carbonate minerals in a four-billion-year-old meteorite that originated near the surface of Mars, the scientists determined that the minerals formed at about 18 degrees Celsius (64 degrees Fahrenheit). "The thing that's really cool is that 18 degrees is not...

New Hypothesis: Pumice Proposed As Home To The First Life Forms
2011-10-05 03:48:56

The glassy, porous, and once gas-rich rock called pumice may have given rise to early life forms, according to a provocative new hypothesis on the origin of life published in Astrobiology, a peer-reviewed journal from Mary Ann Liebert, Inc. Martin Brasier, Richard Matthewman, and Sean McMahon, University of Oxford (U.K.), and David Wacey, University of Western Australia (Crawley), contend that pumice has "four remarkable properties" that would enable it to have had "a significant role in...

Scientists say that aliens may destroy humanity due to the rising greenhouse emissions. Researchers say that extraterrestrial beings might view changes in Earth's atmosphere as symptomatic of a civilization growing out of control and could take drastic action to keep us from becoming a more serious threat. Shawn Domagal-Goldman of Nasa's Planetary Science Division and his colleagues from Pennsylvania State University compiled a list of plausible outcomes that could unfold in the...

Why does Titan, Saturn's largest moon, have what looks like an enormous white arrow about the size of Texas on its surface? A research group led by Jonathan L. Mitchell, UCLA assistant professor of earth and space sciences and of atmospheric and oceanic sciences, has answered this question by using a global circulation model of Titan to demonstrate how planetary-scale atmospheric waves affect the moon's weather patterns, leading to a "stenciling" effect that results in sharp and sometimes...

Over $200,000 in donations from fans have helped place SETI's search for alien life back on track. The institute had previously put the 42-antenna Allen Telescope Array in Northern California on hold due to budget conflicts. SETI (Search for Extraterrestrial Intelligence) said if it could raise $200,000 from the public by August it would be able to turn the array back on. The institute spends $1.5 million annually to keep the array up and running.  Karen Randall, director of...

WASHINGTON, Aug. 8, 2011 /PRNewswire-USNewswire/ -- NASA-funded researchers have found more evidence meteorites can carry DNA components created in space. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO ) Scientists have detected the building blocks of DNA in meteorites since the 1960s, but were unsure whether they were created in space or resulted from contamination by terrestrial life. The latest research indicates certain nucleobases -- the building blocks of our genetic...

NASA scientists are seeing new evidence that suggests traces of water on Mars are under a thin varnish of iron oxide, or rust, similar to conditions found on desert rocks in California's Mojave Desert. Mars could be spotted with many more patches of carbonates than originally suspected. Carbonates are minerals that form readily in large bodies of water and can point to a planet's wet history. Although only a few small outcrops of carbonates have been detected on Mars, scientists believe many...

A top Russian astronomer said on Monday that he expects humanity to encounter alien civilizations within the next 20 years. According to the Interfax news agency, Andrei Finkelstein, director of the Russian Academy of Sciences' Applied Astronomy Institute, said "The genesis of life is as inevitable as the formation of atoms ... Life exists on other planets and we will find it within 20 years." Finkelstein said 10 percent of the known planets circling stars in the galaxy resemble Earth. He...

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...
