Astronomers using ALMA have captured the first direct observation of gas drifting inward within a prestellar core—the slow motion that signals the birth of a new star. This cosmic ‘drift’ rewrites our understanding of star formation.
The Vera C. Rubin Observatory begins its 10-year survey of the southern sky, promising unprecedented discoveries in asteroids, dark matter, and supernovae. All data will be public.
Astronomers have discovered two exoplanets, WASP-193b and Kepler-51d, with densities lower than cotton candy. These ‘super-puffs’ challenge planetary formation models.
NASA’s TESS mission has discovered two ‘super-puff’ planets so light they’re comparable to cotton candy. These Jupiter-sized worlds are the puffiest ever found, challenging planet formation models.
Comet C/2025 R3 dazzles over New Zealand’s Remarkables in March 2025, offering a rare celestial spectacle and new insights into the solar system’s origins.
Discover how amateur astronomer Alan Hale co-discovered Comet Hale-Bopp in 1995, transforming our understanding of the solar system and inspiring millions worldwide.
Astronomers have observed one of the rarest supernovae ever: a giant star destroying itself in a pair-instability explosion, challenging stellar evolution models and seeding the cosmos with heavy elements.
NASA’s Roman Space Telescope launches August 30, eight months ahead of schedule. Its 300.8-megapixel camera captures 100 times more sky than Hubble in one shot.
New research identifies black hole mergers as the cause of massive galaxies that formed stars rapidly then abruptly stopped, solving a long-standing cosmic mystery.
After a 20-year search, astronomers have traced mysterious radio pulses to a ‘vampire’ white dwarf draining its companion star. The discovery rewrites stellar death.
Astronomers capture the first direct image of two supermassive black holes orbiting each other in galaxy 0402+379, 4.4 billion light-years away.
