The 1st Milky Way black hole image was groundbreaking — the next could be even better
The Event Horizon Telescope (EHT), which is a collaboration of radio telescopes all around the world that operate in unison to image supermassive black holes, has achieved its finest resolution yet. In the future, this accomplishment could lead to images of the ring of light around a black hole's event horizon that are 50% sharper
The Myths and Lore of the Milky Way
Sign up for the free Nautilus newsletter: science and culture for people who love beautiful writing. Before our cities lit the night and banished the stars, a gauzy band of faint light and shadows vividly cleaved the night sky. Our name for this band, “Milky Way,” originates in Greek mythology. Heracles, it is told, was
Milky Way’s cosmic neighbors help bring ancient galaxies into focus
Astronomers are spying on the Milky Way's neighbors, assessing the amount of light that escapes from them and how this is connected to each galaxy's physical properties. This deep investigation of our local universe could help scientists better understand the early, distant galaxies currently being observed by the James Webb Space Telescope (JWST) and the Hubble
Milky Way’s Stellar Halo is At Least Two Million Light-Years Across
Astronomers from the University of California, Santa Cruz and elsewhere have discovered 208 new RR Lyrae variable stars in the halo of our Milky Way Galaxy; the most distant of these stars is 320,000 parsecs, or more than a million light-years, from Earth — almost half the distance to the Andromeda galaxy. This illustration shows
New Milky Way mosaic reveals nearly 1,000 strange ‘filaments’ at the heart of our galaxy
Home News Science & Astronomy This MeerKAT image shows the complex emission from the galactic center super bubble, which is is traversed by many parallel radio filaments. The bright dot near the center of this region is the black hole Sagittarius A*. (Image credit: Ian Heywood/SARAO) An unprecedentedly detailed new telescope image of the complex…
See the heart of the Milky Way as it’s never been captured before
We now have a better window than ever into the center of our galaxy, the Milky Way, and it’s filled with exploded stars, magnetic streaks, and a giant black hole. On January 26, the South African Radio Astronomy Observatory (SARAO) released images of the heart of the Milky Way taken using its radio telescope, MeerKAT.…
At the center of the Milky Way is a supermassive black hole. This black hole, dubbed Sagittarius A*, is 4.3 million times bigger than the sun. A recent composite image captured with the Hubble Space Telescope suggests that this Milky Way’s Supermassive Black Hole has been leaking gas or emitting jet-like superheated beams for several…
