Jan. 26, 2024 Physicists discovered stars near the edge of the Milky Way travel more slowly than those closer to its center -- a surprise suggesting our galaxy's gravitational core may have less dark matter ...
Jan. 25, 2024 A new study describes the best method to improve images obtained by the James Webb Science Telescope (JWST) using a mathematical approach called ...
Jan. 17, 2024 Researchers have discovered the oldest black hole ever observed, dating from the dawn of the universe, and found that it is 'eating' its host galaxy to ...
Jan. 17, 2024 High-resolution images captured by the James Webb Space Telescope are offering powerful insights into the complex dust patterns of nearby star-forming ...
Jan. 16, 2024 Astronomers have created the most sensitive radio image ever of a globular cluster, an ancient ball of tightly-packed ...
Jan. 12, 2024 Researchers at NASA's Goddard Space Flight Center have discovered X-ray activity that sheds light on the evolution of ...
Jan. 11, 2024 A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only gave a very general ...
Jan. 9, 2024 In summer 2022, astronomers detected the most powerful and most distant fast radio burst (FRB) ever observed. Now, astronomers have pinpointed the extraordinary object's birthplace -- and ...
Jan. 8, 2024 Astronomers believe they may have found the origin of the universe's giant odd radio circles: they are shells formed by outflowing galactic winds, possibly from massive exploding stars known as ...
Dec. 22, 2023 A whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 ...
Dec. 22, 2023 Researchers have analyzed more than one million galaxies to explore primordial fluctuations that seeded the formation of the structure of the entire ...
Dec. 21, 2023 A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way. At more than 12 billion years old, BRI 1335-0417 is the oldest ...
Dec. 21, 2023 In November 2023, NASA's James Webb Space Telescope observed a massive cluster of galaxies named MACS J0138.0-2155. Through an effect called gravitational lensing, first predicted by Albert ...
Dec. 21, 2023 Supercomputer helped astronomers develop PRIYA, the largest suite of hydrodynamic simulations yet made of large-scale structure in the ...
Dec. 15, 2023 Not all discoveries turn out to be actual new discoveries. This was the case for the extremely red objects (EROs) found in James Webb Space Telescope (JWST) data. Analysis shows that they are very ...
Dec. 14, 2023 Two galaxies in the early universe, which contain extremely productive star factories, have been studied by a team of scientists. Using powerful telescopes to split the galaxies' light into ...
Dec. 6, 2023 Galactic winds enable the exchange of matter between galaxies and their surroundings. In this way, they limit the growth of galaxies, that is, their star formation rate. Although this had already ...
Dec. 5, 2023 Through analysis of high-resolution data from a ten-meter telescope in Hawaii, researchers have succeeded in generating new knowledge about three stars at the very heart of the Milky Way. The stars ...
Dec. 4, 2023 An entirely new way to probe how active black holes behave when they eat has been discovered by an international team of ...
Dec. 4, 2023 A star near the supermassive black hole at the center of the Milky Way Galaxy originated outside of the Galaxy according to a new study. This is the first time a star of extragalactic origin has been ...
