curiosity tracks across dune
2014-02-12 07:45:08

Guy Webster, Jet Propulsion Laboratory NASA's Curiosity Mars rover is continuing its traverse toward enticing science destinations after climbing over a dune spanning a gap in a ridge. The rover covered 135 feet (41.1 meters) on Feb. 9, in its first drive since the 23-foot (7-meter) crossing of the dune on Feb. 6. That put Curiosity's total odometry since its August 2012 landing at 3.09 miles (4.97 kilometers). An animated sequence of images from the low-slung Hazard-Avoidance Camera...

New Techniques Tease Out Building Blocks Of Life In Meteorites
2014-02-04 06:24:52

[ Watch the Video: New Technique For Studying Out-Of-This-World Particles ] Lawrence LeBlond for redOrbit.com - Your Universe Online Scientists have long delved into the mysteries of the origins of life here on Earth and more recently have found evidence pointing to the skies above us. Some evidence has been found in material created in space and delivered to Earth via comets and meteors, containing the building blocks for life. The latest round of evidence comes by way of Michael...

Superhabitable Exoplanet

[ Watch the Video: Are Some Exoplanets More Super Than Earth? ] Brett Smith for redOrbit.com - Your Universe Online The stellar habitable zone (SHZ), or Goldilocks zone, is considered the range of ideal orbital distances from a star for creating the conditions necessary for life. A new paper published recently in the journal Astrobiology argues that some planetary bodies outside this zone may hold environments even more habitable for life than those found here on Earth. The authors...

Lee Rannals for redOrbit.com - Your Universe Online A new image taken by NASA's Mars Reconnaissance Orbiter (MRO) shows the space agency’s Curiosity rover on the surface of Mars viewed from orbit. The new image was taken on December 11, 2013 by MRO’s High Resolution Imaging Science Experiment (HiRISE) camera. Not only does the picture feature Curiosity driving inside Gale Crater, but it also shows tracks the rover’s tires have left behind as it makes its way across the Red Planet....

Super Earths May Be More Like Our Planet Than Previously Theorized

[ 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
2014-01-08 14:32:50

[ 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...

mars curiosity wheel damage

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...

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...
