Webb Just Found Water Around a Dying Star Just 0.55 Light-Years from the Milky Way’s Central Black Hole
3+ hour, 3+ min ago (430+ words) A star remarkably close to the Milky Way’s central black hole has given astronomers a new reason to examine this extreme region. IRS 3 offers a close look at that problem. The star is about 72 million years old, has roughly six…...
Hubble Finds Evidence of an Ancient Galaxy Collision That Transformed the Milky Way
3+ hour, 5+ min ago (349+ words) The Hubble Space Telescope has found evidence that the young Milky Way absorbed a dwarf galaxy about 11.8 billion years ago. This ancient galaxy collision, linked to LKH, occurred roughly 1.8 billion years before the better-known Gaia-Sausage-Enceladus merger. Astronomers identified the event…...
