An international team led by NASA has tested the International Asteroid Warning Network, which successfully tracked a potentially dangerous asteroid as it made a close flyby of the Earth in October. Billed as the first global exercise using a real asteroid to test global response capabilities, the TC4 Observation Campaign observed and plotted the orbit of the asteroid 012 TC4 as it passed within 27,200 mi (43,780 km) of the Earth.
Bay Area scientists announced today that they had detected the detritus cast off by colliding neutron stars 130 million light-years away, a landmark achievement in our quest to explore deep time and space.
Organic molecules once thought to be produced only by life-forms have been found in two separate regions of space: a nearby comet and the debris around a pair of forming stars.
NASA’s Hubble Space Telescope has observed a planet outside our solar system that looks as black as fresh asphalt because it eats light rather than reflecting it back into space. The exoplanet, called WASP-12b, is one of a class of so-called “hot Jupiters,” gigantic, gaseous planets that orbit very close to their host star and are heated to extreme temperatures.
Half the atoms inside your body came from across the universe.
The chances of anything coming from Mars have taken a downward turn with the finding that the surface of the red planet contains a “toxic cocktail” of chemicals that can wipe out living organisms.
Saturn's ice-crusted moon Enceladus may now be the single best place to go to look for life beyond Earth.
Seven alien, Earth-sized worlds bask in the cool, red light of their parent star ( TRAPPIST-1) . The planetary menagerie exists around a star overlooked by other exoplanet hunters, although it is just 12 parsecs (39 light years) from Earth.
