For the first time, astronomers are watching as a supernova’s light bends around a massive galaxy on its way to Earth.
New Stars On Strange Orbits in Milky Way
Astronomers have found two just-born star clusters an incredible 16,000 light-years above the plane of the Milky Way galaxy.
New Stars in the Shadow of a Black Hole
New observations suggest that several dozen low-mass stars, and eventually perhaps even planets, are forming just 2 light-years from our galaxy’s supermassive black hole.
Cepheids Map Milky Way - and Beyond
Cepheid variable stars are helping astronomers see what our galaxy looks like from within.
Tempest in the Teacup Galaxy
New observations of the Teacup Galaxy show that even black holes with wimpy radio jets can quench a galaxy's star formation. An unassuming nearby galaxy nicknamed The Teacup (more formally known as J1430+1339) hides a tempest inside. The supermassive black hole at this galaxy's center is chowing down furiously on…
Before They Were (Binary) Stars
Astronomers have taken a behind-the-scenes look at a set of dense gas clumps, catching a quadruple star system in the fleeting act of formation.
