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…
A record-breaking number of stars has been mapped by a new model that speeds up processing time while allowing smaller scale events, such as supernova explosions, to be incorporated into the simulation alongside larger-scale galactic…
"The discovery of this stream highlights how much is still unknown about the life histories of galaxies, how the hidden universe shapes the realms that we can see."
Astronomers have just discovered a galaxy that produces stars 180 times faster than the Milky Way. And this discovery could answer many questions about the first moments of the universe.
Researchers at the RIKEN Center for Interdisciplinary Theoretical and Mathematical Sciences in Japan, collaborating with The University of Tokyo and Universitat de Barcelona, have delivered the first simulation of the Milky Way that models…
Recently, astronomers have discovered a stellar stream in the galaxy M61, and this discovery is unique because it is as long as the Milky Way. But it will be necessary to conduct further studies to better understand this phenomenon.
