Astronomers witness the unfurling of a black hole-powered mushroom cloud, a baby super-Jupiter, and a magnetic "tunnel" around the solar system.
Astronomers have made the first clear detection of a dusty disk surrounding an exoplanet, which could eventually go on to form moons.
Astronomers investigate the spiral arms of a young star's disk and find evidence of a disk so massive that it could collapse to form planets.
Astronomers thought a super-Earth might orbit nearby Barnard's star. But a new study disputes that claim, arguing that stellar activity might be masquerading as the planetary signal.
Astronomers have found an Earth-size (but not at all Earth-like) planet around an ancient star that has a nice high view of our galaxy.
A new, full analysis of Kepler data finds at least 300 million Earth-size planets in the habitable zone around Sun-like stars in our galaxy.
This week in astronomy news: Distant galaxies that look older than they are and a terrestrial planet that might be drifting through our galaxy.
New research shows stellar flybys are common in our galaxy’s crowded center. That could have both good and bad (but mostly bad) effects on growing planets.
