Astronomers may have discovered a rare type of binary star system, where one star used to orbit inside its partner.

For the first time, astronomers have spotted a rapidly spinning neutron star that is gravitationally bound to a helium star companion. The discovery of this unusual binary system helps confirm a long ...

A spinning neutron star orbits the remnants of a once-massive companion it has stripped to its core.

When people think of black holes, they imagine something dramatic: a star exploding in space, collapsing in on itself, and ...

Space is vast, mysterious, and full of surprises that continue to boggle the minds of scientists and stargazers alike. From ...

As telescopes gaze into space, they also peer back in time. Starlight takes years—sometimes billions—to reach Earth, letting ...
