About 12 billion years ago, a dwarf galaxy known as LKH collided with a young Milky Way and merged with it. This artist’s concept portrays that collision. NASA’s Hubble Space Telescope uncovered definitive evidence of this collision by studying globular star clusters. Illustration: NASA, ESA, Joseph Olmsted (STScI) Our home galaxy, the Milky Way, grew
When Soundgarden Wrote “Black Hole Sun,” they may have inadvertently been onto something. In a new paper in Nature, scientists have chronicled a “black hole star” that’s the size of our solar system and glows bright red in the depth of space. The findings are based on observations from the James Webb Space Telescope, which
Observing across the starry “plains” of space, NASA’s James Webb Space Telescope has taken new images of NGC 2392, nicknamed the Lion Nebula. NASA’s Hubble Space Telescope previously viewed this planetary nebula in 2000, imaging the lion face-shaped target in visible light and revealing features such as the “mane” of hazy, comet-shaped objects. Now Webb
On July 27, technicians at NASA’s Kennedy Space Center in Florida installed a memory card containing 1,350,144 names as part of a commemorative plaque on the Nancy Grace Roman Space Telescope. The names were submitted by people globally, including astronauts from Artemis II and Artemis III. The memory card will travel with the Roman observatory
Since their discovery by NASA’s James Webb Space Telescope in 2022, small red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these compact and extremely distant red sources has been a perplexing scientific endeavor. One popular theory is that the small red dots are supermassive black holes known
NASA’s Neil Gehrels Swift Observatory captured an “orphan” black hole lighting up as it devoured a star on the outskirts of a distant galaxy. For starters, these phenomena are rare and none have ever been seen so far outside the core of a galaxy before. “We were looking for these star destruction events as a
