The cause of the incident, which added to a growing amount of dangerous space junk in low Earth orbit, remains unknown. A decommissioned Russian satellite fractured in space on Wednesday, creating a cloud of debris in low Earth orbit that prompted astronauts aboard the International Space Station to take protective measures. The satellite, which was…

Chris Lintott tries to observe everything from asteroids zipping through the Solar System, to distant galaxies. The way the cosmos reveals its secrets is a story, he thinks, deserves an audience. Luck and scientific stumbles are the cornerstone of astronomy. Stories about lauded geniuses and prize winners are masks, he argues, hiding the more exciting…

Studying distant stars is difficult without absolute flux calibration points—stars that can help astronomers calibrate their instruments. So, NASA—along with George Mason University and the National Institute of Standards and Technology—is going to place an artificial star into geostationary orbit to help improve astronomical observations around the world. Known as the Landolt Space Mission, this…

Rubin Observatory comes online, perhaps at full bore in 2025, this powerful and unique survey telescope, at high altitude in Chile, will survey the heavens in a new and unprecedented way.   Originally named the Large Synoptic Survey…

Since the James Webb Space Telescope began operating two years ago, astronomers have been using it to leapfrog one another millions of years into the past, back toward the moment they call cosmic dawn, when the first stars and galaxies were formed. Last month, an international team doing research as the JWST Advanced Deep Extragalactic…

Scientists have directly imaged eight dim objects accompanying very bright stars within the Gaia data catalog, including so-called “failed stars,” otherwise known as brown dwarfs.  The stars and their companions were originally identified from millions of stars in the Gaia catalog. They were considered ideal for follow-up investigations with the ground-based GRAVITY instrument, an advanced…

CNN — Astronomers are witnessing a never-before-seen spectacle in the cosmos: the awakening of a supermassive black hole at the center of a distant galaxy. In late 2019, a team of astronomers took notice of an otherwise unremarkable galaxy named SDSS1335+0728, 300 million light-years away in the Virgo constellation. A sudden spike in the galaxy’s…

Anyone who has ever performed an internet search will most likely have encountered the phenomenon of the Google Doodle, a graphic or sometimes an animation at the top of the Google search page. These thought-provoking and often amusing illustrations celebrate anniversaries, events and individuals, among them a fair selection of astronomers, space missions, and astronomical…
