At the extremes: A hot Jupiter reveals extreme chemistry on a sizzling world, and a cold Jupiter sheds light on giant planet formation.

Share the joy of stargazing and become part of the legacy of astronomy.

Astronomers aren't holding back this year, with brand-new submissions to this year's highly prestigious (and fictitious) Acta Prima Aprilia.

The evening Moon climbs toward the Arch of Spring, then through it. Orion's Belt levels, the Leaps of the Gazelle cross the zenith, and Saturn and Mars conjoin near brilliant Venus in early dawn.

With the arrival of April, you’re likely to spend more time outdoors under the stars. So why not bring along our monthly Sky Tour astronomy podcast? It provides an informative and entertaining 12-minute guided tour of the nighttime sky. Download the April episode to explore the fascinating movement of four planets in the sky before dawn.

Join us in Pasadena 12-16 June for exceptional science at the 240th meeting of the American Astronomical Society.

The Hubble Space Telescope has revealed a single star whose light has traveled for 12.9 billion years to Earth — the most distant star known.

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.

Procyon Vitals Official name Procyon Other designations Alpha Canis Minoris, HR 2943, HD 61421   Nicknames - Apparent magnitude 0.37 Distance 11.46 light-years Type Main sequence, F5IV-V Color Yellow-white Mass […]

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.
