NASA's Hubble Space Telescope has broken the distance limit for galaxies and uncovered a primordial population of compact and ultra-blue galaxies that have never been seen before.

University of Notre Dame astronomer Peter Garnavich and a team of collaborators have discovered a distant star that exploded when its center became so hot that matter and anti-matter particle pairs were created.

New results from NASA's Chandra X-ray Observatory and the Magellan telescopes suggest that a dense stellar remnant has been ripped apart by a black hole a thousand times as massive as the Sun. I

Astronomers have made the most detailed views yet of space up to 12 billion years back in time.

A new study shows that both stellar collisions and a process sometimes called vampirism are behind this cosmic "face lift.",stars also called blue stragglers

For almost 50 years, astronomers have puzzled over the youthful appearance of stars known as blue stragglers.

Within a decade scientists could be able to detect the merger of tens of pairs of black holes every year, according astronomers. By modeling the behavior of stars, the team finds that they are ideal environments for black holes to coalesce.

The European Space Agency has released the first scientific results from the recently launched Herschel Space Telescope.

The planet orbits a red dwarf star 40 light-years from our Earth, and its surface may be covered in water. But scientists say conditions on this planet would probably be too extreme to support life as we know it.

Physicists propose there may be a new stage for some dying stars. Dubbed electroweak stars, they are fueled by the conversion of quarks to leptons, which prevents or staves off collapse into a black hole.
