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

The waning crescent Moon joins Venus and Jupiter at dawn. In the dark of night, the Guardians of the Pole are no such things, except they are. And thereby hangs a tale. . .

More than 200 planets in the TESS catalogs may be bigger than originally estimated — putting initially Earth-size planets into the super-Earth category.

Meteor-watchers will be busy this month and next. Not only are the Southern Delta Aquariids peaking soon, but they get a boost from additional minor showers.

Astronomers have found a baby system that’s just beginning to build planets — and it can tell us about how and where planet formation starts.

NASA’s TRACERS spacecraft will look at the snap of magnetic field lines at the boundary between the solar wind and Earth's magnetic field.

The newly waxing Moon passes Mars low in the west, then Spica and Antares while growing more robust. At dawn, Jupiter heads toward Venus.

A new image from the Gemini Observatory might show a stellar companion to Betelgeuse, but the discovery is tentative.

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.

Starting September 29th, another moon of sorts will briefly accompany Earth. The house-size asteroid will stick around less than 2 months.

A team of scientists thinks a clustering of ancient impact craters points to a temporary ring around Earth hundreds of millions of years ago.

In this dark-of-the-Moon week, the Cygnus Milky Way crosses the zenith, and Arcturus, Capella, and Fomalhaut come to a certain balance.

Almost 10 years ago, New Horizons finally zipped by Pluto, returning fantastic images. But then it needed a new destination.

A pair of black hole jets powered by a supermassive black hole span far beyond their host galaxy — potentially affecting the cosmic web around it.

Glass beads in samples from China’s Chang’e 5 mission show that volcanic eruptions occurred on the Moon within the past 120 million years or so.

The Royal Observatory Greenwich has announced the winners of the 16th annual Astronomy Photographer of the Year contest.
