Hubble telescope images spiral galaxy NGC 6000
AI에 의해 보고됨
The NASA/ESA Hubble Space Telescope has captured a stunning image of NGC 6000, a spiral galaxy 102 million light-years away in the constellation Scorpius. The picture highlights stars of varying ages, from blue young clusters to a golden older core, while revealing faint remnants of past supernovae. An asteroid photobombed the shot, adding streaks to the cosmic scene.
JWST uncovers chaotic early galaxies in young universe
Astronomers using the James Webb Space Telescope have found that the universe's first galaxies were turbulent and disorderly, far from the stable structures seen today. Led by University of Cambridge researchers, the study examined over 250 galaxies from when the universe was 800 million to 1.5 billion years old. These findings challenge prior views and show a transition from cosmic chaos to ordered formation.
Tiny nearby galaxy hosts massive black hole
A small satellite galaxy of the Milky Way, known as Segue 1, contains a supermassive black hole far larger than expected for its size. This discovery challenges long-held assumptions that such dwarf galaxies are primarily held together by dark matter. Researchers used computer models to reveal the black hole's presence at the galaxy's center.
Astronomers uncover gas bridge between two dwarf galaxies
Scientists at the University of Western Australia's ICRAR node have discovered a massive bridge of neutral hydrogen gas connecting the dwarf galaxies NGC 4532 and DDO 137. This structure spans 185,000 light-years and is located 53 million light-years from Earth. The finding, part of the WALLABY survey, reveals how interactions with the Virgo cluster strip gas from galaxies.
