Three distant galaxies imaged by the James Webb Space Telescope might actually be "dark stars" powered by dark matter annihilation, claims a team of astronomers.

India is headed back to the Moon with its ambitious new Chandrayaan 3 mission.

Venus, Mercury, and Mars, very unequal, gather low in the western twilight with the crescent Moon stepping over them and Regulus in their midst. And do you know which way the Kite of Boötes bends?

New research proposes a way for fast radio bursts to escape the confines of a magnetized star and jet out into space — by getting help from theoretical particles called axions.

NASA's Perseverance has sniffed 10 rock samples and found signatures of organic molecules, a sign of a complex geochemical past.

Deep-sky objects may appear static throughout our lifetime but by carefully "blinking" archival and current images we can discern real changes in their appearance.

Satellites’ leakage radiation, now detected for the first time, may become a major problem for radio astronomy, as “megaconstellations” keep on growing.

Mars meets Regulus while Venus looks on. Scorpius comes to its July height — bearing its double stars, Cat's Eyes, and Little Cat's Eyes. And keep a lookout for noctilucent clouds at the end of dusk.

The intrepid infrared explorer is offering astronomers a jump back in time, enabling them to see quasars at earlier times than ever before.
