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!

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.
