The Expedition 48 crew continued more eye exams and ongoing research to understand how microgravity shifts body fluids toward the upper body. Two NASA astronauts also checked out U.S. spacesuit safety gear and tools....

In Sept. 2014, NASA's Swift spacecraft detected a gamma-ray burst (GRB 140903A). By combining the data with x-ray and optical observation, astronomers determined that it was caused by a merger of neutron stars in a galax...

NASA's Cassini spacecraft has found deep, steep-sided canyons on Saturn's moon Titan that are flooded with liquid hydrocarbons. The finding represents the first direct evidence of the presence of liquid-filled channels o...

This false-color view from NASA's Cassini spacecraft shows clouds in Saturn's northern hemisphere. The view was produced by space imaging enthusiast Kevin M. Gill, who also happens to be an engineer at NASA's Jet Propuls...

Are massive black holes hiding in the halos of galaxies, making up the majority of the universe's mysterious dark matter? This possibility may have been ruled out by a star cluster in a small galaxy recently discovered o...

Just when you think Tabby's Star can't get any weirder, it goes and does. You know this star: It undergoes very odd dips in brightness that have defied explanation. The star, formally called KIC 8462852 (but nicknamed Ta...

Are massive black holes hiding in the halos of galaxies, making up the majority of the universe's mysterious dark matter?Roughly 27% of the mass and energy in the observable universe is made up of "dark matter" -- matter...

Twenty years ago, NASA scientists and their colleagues announced they had spotted possible signs of Mars life in a meteorite known as Allan Hills 84001 (ALH 84001). The claim ignited a scientific controversy that lingers...
