Super Earths May Be More Like Our Planet Than Previously Theorized
2014-01-09 06:55:52

[ Watch the Video: More Like Earth? Exoplanet Scientists Weight In ] Brett Smith for redOrbit.com - Your Universe Online It seems like the discovery of Earth-like planets is always announced with one caveat – the planet discovered probably isn’t much like Earth. Many of these are "super-Earths," several times larger than our own planet and thought to be completely covered in water. However, a new study to be published in an upcoming edition of the Astrophysical Journal, has...

Habitable Zone Larger Than Believed

[ Watch the Video: Life In The Habitable Zone ] Lee Rannals for redOrbit.com - Your Universe Online A new paper published in the journal Planetary and Space Science claims planets that were once thought uninhabitable may actually be able to contain life after all. University of Aberdeen scientists say that earth-sized planets are able to support life at least ten times farther away from stars than previously thought. This idea challenges the traditional 'habitable zone' theory...

redOrbit Staff & Wire Reports - Your Universe Online Having successfully completed a software upgrade, the team operating NASA’s Mars rover Curiosity now plans to check the vehicle’s wheel for wear-and-tear, officials with the US space agency announced on Friday. Jim Erickson of NASA’s Jet Propulsion Laboratory (JPL), manager of the Mars Science Laboratory project, said Curiosity is now running version 11 of its flight software. This is the third upgrade since the rover landed...

Over the past year, Mars exploration has made the biggest headlines, particularly due to NASA’s...

NASA's Jet Propulsion Laboratory To Test New Supersonic Decelerator Technology
2013-12-18 06:35:49

NASA's Jet Propulsion Laboratory A giant crane will tower above NASA's Jet Propulsion Laboratory in Pasadena, Calif., shooting out of a hilly mesa like an oversized erector set, ready to help test components of NASA's Low Density Supersonic Decelerator (LDSD) project. The goal of the challenging technology, led by JPL, is to enable a future mission to Mars or other planetary bodies that uses heavier spacecraft and lands them at locations that were previously not achievable. The...

Mars Rock Dating Analysis
2013-12-13 10:15:24

Brett Smith for redOrbit.com - Your Universe Online While scientists have analyzed the age of rock samples from other planetary bodies before, the work has always been performed on Earth. Now, an international team of scientists has announced the first-ever geological analysis of a rock sample performed on another celestial body – Mars. According to a report in the journal Science Express, the on-planet analysis could lead to a greater understanding of Mars’ geologic history and the...

Ancient Martian Lake May Have Supported Microbial Life
2013-12-09 12:40:55

[ Watch the Video: Evidence Of Ancient Lake Found Within Gale Crater ] Lee Rannals for redOrbit.com - Your Universe Online A crater found on Mars is actually an ancient lake bed that could have contained the proper conditions to have supported life on the Red Planet, according to a new finding by NASA’s Curiosity rover. NASA scientists announced at the American Geophysical Union meeting in San Francisco on Monday that they have discovered the fossil remains of a lake inside Gale...

NASA Runs Three Mass Spectrometers In Three Different Places In Space
2013-12-06 17:21:48

Lee Rannals for redOrbit.com – Your Universe Online NASA said that three of its instruments built at the Goddard Space Flight Center were all running three experiments of the same kind at different places in space. The mass spectrometers are designed to take in atmospheric, rock or soil samples and identify particular molecules in them. The instruments help identify gases in atmospheric samples or gases that get released from rock or soil samples as they are processed. “At the...

Curiosity Rover Fires Over 100,000 Laser Shots To Date
2013-12-06 04:10:51

[ Watch the Video: Laser-Zapping Milestone For A 'Curious' Rover ] April Flowers for redOrbit.com - Your Universe Online NASA's Curiosity Mars rover has fired the shot heard round the solar system — 100,000 shots, to be exact. The rover has fired the laser it uses as one way to check which chemical elements are in rocks and soils 100,000 times. One of a series of 300 used to investigate 10 locations on a rock called "Ithaca," the 100,00th shot took place this past October. The...

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...
