Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the galaxies’ rotating necks would force them to fly sideways. But now, scientists have found a series of galaxies that do not seem to have their dark matter completely. The latest in this string, known … Read more
Astronomers have made an unprecedented discovery about winds blowing from the star-forming galaxy M82revealing a speed that shatters past expectations. The new data, collected by NASA’s XRISM spacecraft, confirmed wind speeds of over 2 million miles per hour, much faster than previously thought. Published in Naturethis landmark study not only pushes the boundaries of space … Read more
Astronomers have revealed a rare triple-double radio galaxy 7.5 billion light-years from Earth. Known as J022248−060934, this mysterious system sheds new light on the behavior of supermassive black holes. With only six other clusters of its kind previously known, this discovery pushes the boundaries of our understanding of cosmic phenomena and could pave the way … Read more
It is not often that astronomers can see large changes in the brightness of a galaxy within a few years. Most galaxies change in brightness (and other properties) over millions or billions of years. So, when images of the distant 10-billion-light-year galaxy J0218-0036 showed that it dimmed to a twentieth of its previous brightness in … Read more
Amazing new photo from The Hubble Telescope which reveals the secrets of IC 486The barred galaxy is 380 million light-years away, showing the intense interaction between star formation and the incredible energy of a supermassive black hole. The discovery, which is part of a major investigation by the European Space Agency (ESA), provides unprecedented insight … Read more
