Passing stars may have altered Earth's orbit, and its climate, many times throughout cosmic history. New research digs into what that means when it comes to understanding our planet's past.

The discovery or an ultra-tiny white dwarf could reveal how stars smaller than Jupiter are born.

Twinkling stars can throw off telescope observations. To correct that, observatories like the Gemini North telescope in Hawaii create 'artificial stars' with lasers to hone their equipment.

The powerful James Webb Space Telescope captured a starburst complex in the Large Magellanic Cloud, with stunning results.

A new cosmic crime scene reconstruction tells the full story of a star ripped apart by a ravenous black hole, revealing a previously unknown aspect of these tidal disruption events.

A new study suggests the disk was made to accurately represent the brightest stars at least 2,400 years ago, possibly as an aid for planting crops. But other experts are not convinced.

Scientists modeled how black holes and neutron stars form after dying stars collapse, and explained why some get a hard 'kick' into interstellar space.

An entire universe made of 'dark' particles could exist within our own, and astronomers may know the first place to look: In the mysterious hearts of supposed 'mirror stars'.

New research suggests that if tiny primordial black holes created during the Big Bang exist, some of them may have been snared by stars and are now forced to eat their way out.
