Expedition 53 Commander Randy Bresnik and Flight Engineer Mark Vande Hei of NASA will head outside the International Space Station at approximately 8 a.m. EDT Tuesday to begin a 6.5-hour spacewalk. Live coverage will be available on NASA Television and the agency's website beginning at 6:30 a.m.


Ten observatories in six European countries teamed up for recent observations of a stellar occultation by the dwarf planet Haumea, which surprisingly show a narrow and dense ring orbiting the dwarf planet.


There's no map showing all the billions of exoplanets hiding in our galaxy -- they're so distant and faint compared to their stars, it's hard to find them.


Astronomers have shed fresh light on the importance of hydrogen atoms in the birth of new stars.


Scientists have long assumed that all the planets in our solar system look the same beneath the surface, but a study published in Geology on Oct. 4 tells a different story.

Astronomers have identified a bumper crop of dual supermassive black holes in the centers of galaxies.


Depressions such as impact craters can act as traps for sediments that have been blown in from elsewhere, accumulating in various patterns whipped up by strong winds.


A new study shows that an atmosphere was produced around the ancient Moon, 3 to 4 billion years ago, when intense volcanic eruptions spewed gases above the surface faster than they could escape to space.

It might be lingering bashfully on the icy outer edges of our solar system, hiding in the dark, but subtly pulling strings behind the scenes: stretching out the orbits of distant bodies, perhaps even tilting the entire solar system to one side.


One of the most mysterious stellar objects may be revealing some of its secrets at last.


An unexpectedly strong blast from the Sun hit Mars this month, observed by NASA missions in orbit and on the surface.
