New research shows that not only can gas gather itself into planet-size objects, but those objects then are flung throughout the galaxy in a game of cosmic 'spitball.'
The 11 farthest known stars in our galaxy are located about 300,000 light-years from Earth. New research shows that half of those stars might have been ripped from another galaxy.
Astronomers have been surprised to see a huge shadow sweeping across a disk of dust and gas encircling a nearby star, and incredibly, it takes 16 years for just one rotation.
NASA's NuSTAR (Nuclear Spectroscopic Telescope Array) recently identified two gas-enshrouded supermassive black holes, located at the centers of nearby galaxies.
