Could an ocean – likely needed to sustain life – even survive on a planet orbiting close to a dead star?

Astronomers may have solved the mystery of how hypervelocity white dwarfs rocket out of the Milky Way at breakneck speeds.

Some stars in the universe grow to 300 times larger our own sun. But how do they get so big, and how do they sustain their mass?

Astronomers have learned how to find supernova explosions in their earliest stages, giving us an unprecedented look at how these stars blow up.

Astronomers discovered a star-triggered explosion shaping its dusty disk, revealing a far more chaotic and intense environment than previously thought.

The star, called DFK 52, is a member of a cluster of similar red supergiants, but it's losing mass at an extreme rate never seen before.

Astronomers spot a rare stellar bridge in Abell 3667, revealing an aggressive galaxy merger and new clues about dark matter.

Ultimately, we do not understand where glitches come from or exactly what's going on inside pulsars.

Astronomers have discovered the first evidence of a white dwarf wiped out by a double-detonation supernova, also providing space-lovers with stunning eye-candy.

Star RIK 113 is busy making a new planet in its protoplanetary disk as seen in this new image from the Very Large Telescope.
