Could life exist on planets in the star system closest to ours, Alpha Centauri? Dangerous X-ray radiation makes it unlikely for the single exoplanet found so far. But new data suggest better odds for any new planets yet to be discovered.
On Thursday, 2 astronauts aboard the International Space Station will conduct a 6 1/2 hour spacewalk. NASA’s live coverage begins at 10:30 UTC (6:30 a.m. EDT). The spacewalk itself is scheduled to start at 12:10 UTC (8:10 a.m. EDT).
Since the 1970s, scientists have treated pulsars and magnetars as 2 distinct populations of objects. Now they think they might be stages in a single object’s evolution. A new NASA ScienceCast has more.
Astronomers call them G-objects. The 2 previously known ones came incredibly close to the Milky Way’s central black hole, yet survived. Now astronomers report 3 more of these mystery G-objects near the heart of our galaxy.
Exoplanets are worlds orbiting distant stars. Until recently, they existed only in the realm of imagination and probability. Now we know thousands! NASA’s Exoplanet Travel Bureau lets you explore them.
