At the heart of our galaxy lies a cosmic puzzle: although the Galactic Center is packed with star-making material, massive stars form there surprisingly slowly. Using NASA's retired SOFIA observatory, ...

Newswise — A team of astronomers has made a surprising discovery using the U.S. National Science Foundation Green Bank Telescope (NSF GBT): eleven fast-moving clouds of cold, neutral hydrogen gas—akin ...

An extremely deep Chandra X–ray Observatory image of a region near the center of our galaxy has resolved a long-standing mystery about an X-ray glow along the plane of the galaxy. The glow in the ...

All motion is relative. That simple fact makes tracking the motion of distant objects outside our galaxy particularly challenging. For example, there has been a debate among astronomers for decades ...

The XRISM collaboration has discovered flows of hot gas in the core of the Centaurus Cluster. By comparing state-of-the-art X-ray measurements from the XRISM satellite with numerical simulations, they ...

New research suggests that dark matter may once again hold the key to one of astronomy’s enduring mysteries: the excess of gamma rays shining from the Milky Way’s center. By modeling the galaxy’s ...
