Researchers Show Evidence Of Common Mineral Capable Of Making, Breaking Bonds
2014-07-30 03:37:00

Arizona State University ASU team shows evidence for one mineral affecting the most fundamental process in organic chemistry: Carbon-hydrogen bond breaking and making Reactions among minerals and organic compounds in hydrothermal environments are critical components of the Earth's deep carbon cycle, they provide energy for the deep biosphere, and may have implications for the origins of life. However, very little is known about how minerals influence organic reactions. A team of...

NASA Issues RFI For Commercial Mars Data Relay Satellites
2014-07-25 03:05:46

NASA's Jet Propulsion Laboratory NASA has issued a Request for Information (RFI) to investigate the possibility of using commercial Mars-orbiting satellites to provide telecommunications capabilities for future robotic missions to the Red Planet. "We are looking to broaden participation in the exploration of Mars to include new models for government and commercial partnerships," said John Grunsfeld, associate administrator of NASA's Science Mission Directorate at the agency's...

redOrbit Staff & Wire Reports - Your Universe Online Industrial pollution could help in the Search for Extraterrestrial Intelligence (SETI), claim Harvard-Smithsonian Center for Astrophysics (CfA) researchers who have started looking for signs of pollutions on other worlds. According to the study authors, by studying exoplanet atmospheres, scientists can look for gases such as oxygen and methane that only exist together if they are replenished by microbial life. In addition, they...

exoplanets need oceans to be habitable
2014-07-22 04:02:47

Brett Smith for redOrbit.com - Your Universe Online While many previous studies on habitable planetary conditions have focused on the atmosphere, a new study from UK researchers at the University of East Anglia has found that the dynamics of a planet’s ocean is crucial to supporting life. Published in the journal Astrobiology, the new study shows oceans help to moderate climate on a global scale. “The number of planets being discovered outside our solar system is rapidly...

April Flowers for redOrbit.com - Your Universe Online A new study from University of Oregon (OU) geologist Gregory Retallack suggests that soil samples taken by NASA's Mars Curiosity rover contain evidence that Mars was once much warmer and wetter. His findings, published online in Geology, are based on images and data of 3.7 billion year old soil collected in the Gale crater. Previous rovers have revealed the Martian landscape is littered with loose rocks created by impacts or layered...

Laser-Induced Spark on Mars
2014-07-17 04:00:42

Guy Webster, NASA Jet Propulsion Laboratory Flashes appear on a baseball-size Martian rock in a series of images taken Saturday, July 12 by the Mars Hand Lens Imager (MAHLI) camera on the arm of NASA's Curiosity Mars Rover. The flashes occurred while the rover's Chemistry and Camera (ChemCam) instrument fired multiple laser shots to investigate the rock's composition. ChemCam's laser has zapped more than 600 rock and soil targets on Mars since Curiosity landed in the planet's Gale...

redOrbit Staff & Wire Reports - Your Universe Online Since its safe landing in August 2012, NASA's Curiosity Mars rover has been busily carrying out its assigned tasks and making new discoveries. Yesterday, NASA released a new image from the intrepid little rover in which it shows an iron meteorite encountered on its travels. The meteorite, dubbed "Lebanon," is similar in shape and luster to iron meteorites found on Mars by the previous generation of rovers, Spirit and Opportunity....

NASA Many scientists believe we are not alone in the universe. It's probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone -- just as it did here on planet Earth. This basic question about our place in the Universe is one that may be answered by scientific investigations. What are the next steps to finding life elsewhere? Experts from NASA and its partner institutions addressed this question on Monday, July 14, at...

Distant Earths May Need Balanced Friction Tides To Support Life
2014-07-10 12:52:42

Gerard LeBlond for redOrbit.com - Your Universe Online Friction generates heat and NASA scientists have developed a computer model that shows how friction may help distant Earth-sized planets survive dangerous orbits. Other star systems commonly house Earth-sized planets. To some, friction heat could be destructive, but given the correct amount of heat, it could be helpful in creating conditions to support life. “We found some unexpected good news for planets in vulnerable orbits....

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

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...
