Scientists have found a "black widow binary," a neutron star circling and slowly consuming a smaller companion star, as its arachnid namesake does its mate.

A newly discovered celestial object can be viewed as an ancestor of supermassive black holes. It was born relatively soon after the Big Bang.

The first ever look at a baby gas giant in its earliest stages provides evidence for a long-debated alternative theory of how Jupiter-like planets form.

A nearby sun-like star may help solve a 300-year-old mystery of the "Maunder Minimum," a 70-year period when sunspots were incredibly rare.

Researchers may have cracked the case of massive stars that are further from their birthplaces than should be possible based on their life spans.

When a black hole eats a star, it produces a "tidal disruption event" that can outshine the light of every star in the host galaxy for months or even years

A strangely shaped spot on the surface of a baby star 450 million light-years away reveals new insights into how our solar system formed.

The first observation of a cosmic boomerang effect offers new insights into how galaxies grow, live, and die.

An odd metallic star called LP 40-365 is hurtling out of the Milky Way galaxy at absurd speed, researchers say. It's "shrapnel" from an exploding star.

New research shows that many stars in the Milky Way galaxy may have Earth-like planets in their orbit. The finding is somewhat at odds with previous work.
