Like comets? We've got 11 frozen fuzzies to share with you in the coming months, including a couple that could become fine binocular objects.

Conventional planet formation scenarios have Neptune and Uranus forming closer to the Sun. But a new study shows that the ice giant planets could have formed right where they are now.

The transit of a large cloud of protoplanetary rubble across the face of a young star gave the Spitzer Space Telescope our best view yet of planetary evolution in action.

This faint ring of radio emission might signal a momentous event in galactic evolution. Then again, it might be something else entirely.

What constellation trots behind Sirius and Canis Major across the southern sky? Puppis, not a puppy but the poop deck of Argo Navis. In this dark of the Moon, try for the Clown-Face Nebula high in Gemini. And the three dawn planets dance through two more isosceles triangles.

A census of hundreds of thousands of subgiant stars in our galaxy provides a window into the Milky Way's early history.

Forty years ago, NASA's Magellan mission “closed the book” on Venus. Now, a new generation of astronomers think the planet next door deserves a second chance.

The first quantitative assessment of professional telescopes’ carbon footprint finds that these facilities contribute more emissions than all other astronomy research activities combined.

Nature proves truth is still stranger than fiction: A pulsar has shot energetic particles in a thin, straight line that extends for light-years into space. The discovery might explain how antimatter makes its way to Earth.

Sirius sparkles on the corner of the Meat Cleaver, two open clusters hide under the Cleaver's handle, Orion's Belt levels out for the turning of spring, and Venus, Mars and Saturn slow-dance at dawn.

As Saturn returns to the morning sky, will this otherwise serene-looking planet experience another bout of severe weather? Keep your eyes peeled for white spots!

AAS Nova reports on a "super-puff" exoplanet that's nearly 15 times less dense than Jupiter.

Mission teams presenting at this week's Lunar and Planetary Science Conference provided updates on the Perseverance and Zhurong rovers at Mars, Chang'e 5's lunar sample return, and more.

Sirius, bright dogtag of Canis Major, offers observing challenges day and night. The Big Dipper balances Cassiopeia, and the nearly full Moon occults a Leo star.

Researchers gear up for Artemis and a new generation of lunar exploration, with a look at samples from the final crewed mission to the Moon.

The detection of a complex organic molecule in the disk around an infant star suggests prebiotic chemistry starts in the space between stars.

The United Arab Emirates' Hope Probe, on a wide orbit around Mars, provides views of the dynamic Red Planet.

The discovery of the first quadruple asteroid system raises the question: Is there a limit to how many moons an asteroid can have?

We’re drawn to the night sky for different reasons. Wonder. Joy. Discovery. And sometimes, for relief.

Astronomers combined forces to confirm that a black hole proposed to lie a mere 1,000 light-years away isn’t really there.
