Researchers have discovered a rare ring-galaxy duo that appears to harbor a supermassive black hole formed through direct collapse

Gravitational-wave astronomers have detected the collision of two beefy black holes, which created the most massive merger-made black hole found thus far.

In early dawn on Saturday the 12th, Taurus uses Venus to open his very rare, strikingly brilliant second eye. In the following days the eye slips out of place.

Comet Tsuchinshan-ATLAS has delighted observers already, but its morning run was only a warm-up — wait till you see what's coming.

New analysis of Betelgeuse's brightness variations and other data points to a small, close companion for this giant star.

Come along on a guided tour of the stars and planets that you’ll see overhead during October. Ponder the Moon’s whereabouts; spot four planets and a fast-moving comet, and watch for meteors shed by Halley’s Comet.

The Clinton B. Ford Observatory, once used for variable star observations, has fallen to wildfires.

On these moonless evenings, Cassiopeia shows some of its inner workings. The Circlet of Pisces offers a very red star next to a little-known cross. From Vega, Lyra points away from the head of Draco.

As Saturn's rings narrow, now's the time for its moons to shine.
