The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, according to new research. Cosmologists at Durham University, UK, used a new technique combining the highest-resolution supercomputer simulations that exist, alongside novel mathematical modelling, predicting the existence of missing “orphan” galaxies.Continue Reading
Researchers have found clouds of cold gas embedded deep within larger, superheated gas clouds — or Fermi bubbles — at the Milky Way’s center. The finding challenges current models of Fermi bubble formation and reveals that the bubbles are much younger than previously estimated. “The Fermi bubbles are enormous structuresContinue Reading
Astronomers have discovered a huge filament of hot gas bridging four galaxy clusters. At 10 times as massive as our galaxy, the thread could contain some of the Universe’s ‘missing’ matter, addressing a decades-long mystery. The astronomers used the European Space Agency’s XMM-Newton and JAXA’s Suzaku X-ray space telescopes toContinue Reading
An international team of astronomers has trained a neural network with millions of synthetic simulations and artificial intelligence (AI) to tease out new cosmic curiosities about black holes, revealing the one at the center of our Milky Way is spinning at nearly top speed. These large ensembles of simulations wereContinue Reading
New research led by Dr. James De Buizer at the SETI Institute and Dr. Wanggi Lim at IPAC at Caltech revealed surprising results about the rate at which high-mass stars form in the Galactic Center of the Milky Way. The researchers based their study primarily on observations from NASA’s now-retiredContinue Reading
