WASHINGTON, Sept. 19, 2013 /PRNewswire-USNewswire/ -- Data from NASA's Curiosity rover has revealed the Martian environment lacks methane. This is a surprise to researchers because previous data reported by U.S. and international scientists indicated positive detections. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The roving laboratory performed extensive tests to search for traces of Martian methane. Whether the Martian atmosphere contains traces of the gas has...

Sun Intensity Will End Life On Earth In No More Than 3.25 Billion Years
2013-09-19 10:33:04

[ Watch the Video: Earth Will Enter The Hot Zone In Several Billion Years ] Brett Smith for redOrbit.com - Your Universe Online In one of the longest range weather forecasts ever made, a team of UK scientists has determined that the sun’s growing intensity will lead to the evaporation of the oceans and end of life on Earth in about 1.8 to 3.2 billion years – according to a new report published in the journal Astrobiology. Using planets outside the Solar System and their stars as...

Robotic Snake On Mars

[ Watch the Video: ESA Wants To Send A Robotic Snake To Mars ] Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) is looking into the idea of sending a snake to Mars in order to help scientists deepen their knowledge about the Red Planet. Researchers are reportedly developing a snake-like robot that could be paired up with a rover to help future explorers investigate regions that are typically inaccessible. NASA's Curiosity and Opportunity rovers have...

The Search For Life On Mars Begins On Earth, With A Smartphone Camera
2013-09-11 07:37:43

redOrbit Staff & Wire Reports - Your Universe Online Researchers have created a part-human, part-machine “cyborg astrobiology system” that uses a basic mobile phone camera to search for proof of past or present life in planetary analogue sites on Earth. Developed by Patrick McGuire from the Freie Universität in Berlin, Germany, and colleagues, the system involves having a human astrobiologist obtain initial images of his or her surroundings using a mobile phone camera. These...

Sutter's Mill Meteorite Considered Scientific Gold
2013-09-11 05:44:09

April Flowers for redOrbit.com - Your Universe Online Researchers from Arizona State University (ASU) have made an important discovery about the possible inventory of molecules available to the early Earth. Sandra Pizzarello, a research professor in ASU's Department of Chemistry and Biochemistry, led the team in examining the Sutter's Mill meteorite - which exploded in a blazing fireball over California last year - to find that it contains organic molecules not previously found in any...

ExoMars Rover To Look For Microbial Life
2013-09-10 14:49:55

John P. Millis, PhD for redOrbit.com - Your Universe Online In 2018, the European Space Agency (ESA) will launch a new mission to Mars called ExoMars. Armed with new instruments, this explorer will beam back information about various conditions and properties on the Red Planet’s surface. One such instrument will be the Raman spectrometer – a device similar to a bomb detector that will search for evidence for life. The Raman spectrometer has the ability to detect life that has been...

NASA Developing TextureCam Smart Camera System
2013-09-09 19:22:06

[ Watch the Video: Smart Cameras For Future Mars Rovers ] Brett Smith for redOrbit.com – Your Universe Online As urgent as interplanetary exploration might seem, NASA must deal with a significant communication delay that acts as a bottleneck between robotic explorers like the Curiosity rover on Mars and scientists here on Earth. To help address that problem, a team of scientists based at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif. have developed a new camera...

Lee Rannals for redOrbit.com - Your Universe Online Most people have someone they know who has a job they are a little envious of, but there are few people in this world who have careers that even some of the most coveted positioned people envy — driving a rover on Mars. Last year, NASA landed its fourth rover on Mars and kickstarted a mission that would unveil more about the Red Planet than ever before. This rover has provided incredible imagery of our neighboring planet, and has...

Exoplanet With Water-Rich Atmosphere
2013-09-06 07:43:41

John P. Millis, PhD for redOrbit.com - Your Universe Online The search for a habitable planet beyond Earth is on. Scientists have been searching the heavens to find an exoplanet that is just the right distance from its host star to support liquid water, all the while targeting a surface gravity we would be familiar with and an atmosphere oozing with oxygen. Such a planet has not yet been found, but progress has been made, and we continue to find smaller and smaller planets closer to the...

New Evidence Suggests Earthlings Started Life As Martians
2013-08-29 07:02:33

Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists have long posited life on Earth may have started somewhere else in the universe, many pointing to the Red Planet. Now, new evidence is emerging that may hold some truth to that long-debated theory. Professor Steven Benner, from the Westheimer Institute for Science and Technology, gave a speech today at the Goldschmidt 2013 conference in Florence, Italy describing how life on Earth may have kickstarted on Mars. Benner...

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...

Panspermia -- Panspermia is a theory (more directly described as a hypothesis, as there is no compelling evidence yet available to support or contradict it) that suggests that the seeds of life are prevalent throughout the universe and life on Earth began by such seeds landing on Earth and propagating. The theory has origins in the ideas of Anaxagoras, a Greek philosopher. An important proponent of the theory was the British astronomer Sir Fred Hoyle. There is some evidence to...
