New simulations of Milky Way-like galaxies reveal that the strange split between two chemically distinct groups of stars may arise from several very different evolutionary events. Bursts of star formation, shifts in flowing gas, and even…
Astronomers have observed celestial objects that manage to survive the supermassive black hole located at the center of our galaxy. And it seems that the environment around this colossal structure is calmer than expected.
New research and observations with the VLT's ERIS instrument show that some stars are following predictable orbits near Sagitarrius A-star, the Milky Way's supermassive black hole. This goes against the established idea that the black hole…
New simulations reveal that the Milky Way’s odd split between two chemically distinct groups of stars isn’t a universal galactic rule—it’s just one of many possible evolutionary paths. By recreating dozens of Milky Way–like galaxies,…
A distant spiral galaxy called Alaknanda has been found at a time when such orderly systems were thought impossible. With clear spiral arms and intense star formation, it resembles a young version of the Milky Way. JWST data and…
A surprisingly mature spiral galaxy named Alaknanda has been spotted just 1.5 billion years after the Big Bang—far earlier than astronomers believed such well-structured galaxies could form. With sweeping spiral arms, rapid star formation,…
Astronomers using NASAs James Webb Space Telescope have identified a massive spiral galaxy that resembles the Milky Way but existed when the Universe was only about 1.5 billion years old. Named Alaknanda, after a Himalayan river paired…
Astronomers recently discovered 53 quasars that emit jets of matter at the speed of light. And that's not all, because they also extend over more than 7.2 million light-years, which is much larger than the entire Milky Way.
Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide insight into how stars form within giant…
Observations of the supermassive black hole at the heart of the Milky Way, Sagittarius A*, collected by the James Webb Space Telescope, have allowed scientists to better understand how this cosmic titan fires off flares.
Research led by the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) in Japan has successfully performed the world’s first Milky Way simulation that accurately represents more than 100 billion individual…
