Artist’s conception of 55 Cancri e, a searingly hot, carbon-rich world. Image Credit: ESA/Hubble, M. Kornmesser Exoplanets are now being discovered by the thousands, but most are so far away that determining anything specific about their composition or atmosphere is currently very difficult. But technology keeps advancing, and scientists are now starting to […] 
The “Chemical Laptop” being designed by NASA to help search for evidence of alien life elsewhere in the Solar System. Photo Credit: NASA One of NASA’s primary objectives, and the one which most excites the general public, is the search for evidence of life elsewhere, whether in our own Solar System or on […] 
Mars used to have a thicker atmosphere and water on its surface, but what happened to that atmosphere has been a mystery. New research may finally help answer that question. Image Credit: M. Kornmesser/ESO The question of how Mars changed from a once wet world to the much colder and drier one we […] 
Does life spread through the galaxy like an infectious disease, with “bubbles” of inhabited planets? Image Credit: Harvard-Smithsonian CfA We still don’t know if there is life elsewhere in the universe, but scientists are working on techniques to better understand how it may have originated anyway, in the event that such alien biology […] 
Self-portrait of the Curiosity over in Gale crater on Mars. Part of Mount Sharp is in the background. Image Credit: NASA/JPL-Caltech/MSSS NASA’s Curiosity rover has just reached its third anniversary milestone on Mars, after landing in Gale crater on Aug. 5, 2012, and since then has made some incredible science discoveries, with more […] 
Methane has been discovered in some meteorites originating from Mars. Could it be a clue to life? Image Credit: Michael Helfenbein The puzzle of methane on Mars has taken an interesting new twist: For the first time, the gas has been detected within Martian meteorites. The finding adds another layer to the ongoing […] Despite decades of searching, definitive evidence for life on Mars, past or present, has still remained elusive and controversial. Confirmation of such a finding would need to be thoroughly tested and documented, and now researchers at the University of Kansas have developed a new technique that they hope would help to do just that, […] Artist’s conception of super-Earth exoplanet 55 Cancri e, before and after volcanic activity on its day side. The surface may be partially molten. Image Credit: NASA/JPL-Caltech/R. Hurt Discovering new exoplanets has become rather routine in the last few years, but determining just what conditions exist on any of them is naturally more difficult, […] Radar view of Ligeia Mare, a large hydrocarbon sea on Titan. The original version is on the left and the enhanced, “despeckled” version is on the right. Image Credit: NASA/JPL-Caltech/ASI Saturn’s largest moon Titan is a fascinating world, uniquely alien yet eerily Earth-like in many ways, with its rain, rivers, lakes, seas, and […] |
