Supermassive black holes alter galactic chemistry
Tokyo, Japan (SPX) Sep 18, 2023 New research shows that the supermassive black hole at the center of a galaxy can have a direct impact on the chemical distribution of the host galaxy. This provides another piece of the puzzle for understanding how galaxies evolve. It is well known that active supermassive black holes can produce major changes their host galaxies by heating up and removing the interstellar gas in the galaxy. But the compact sizes of black holes, the long distances from Earth, and obscuration by dust in the galaxi ... read more |

The universe caught suppressing cosmic structure growthAnn Arbor MI (SPX) Sep 12, 2023 As the universe evolves, scientists expect large cosmic structures to grow at a certain rate: dense regions such as galaxy clusters would grow denser, while the void ... more 
Webb confirms accuracy of Universe's expansion rate as measured by HubbleBaltimore MD (SPX) Sep 15, 2023 The rate at which the universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos. However, a persistent ... more 
Matter comprises of 31% of the total amount of matter and energy in the universeChiba, Japan (SPX) Sep 15, 2023 "Cosmologists believe that only about 20% of the total matter is made of regular or 'baryonic' matter, which includes stars, galaxies, atoms, and life," explains first author Dr. Mohamed Abdullah, a ... more 
Ravenous black hole consumes star every time it passes byLeicester UK (SPX) Sep 11, 2023 A star like our own Sun in a nearby galaxy is gradually being eaten away by a small but ravenous black hole, losing the equivalent mass of three Earths every time it passes close. The discovery by U ... more |

Space-based quantum science lab keeps getting better
Pasadena CA (JPL) Aug 08, 2023 The agency's Cold Atom Lab is getting its second major upgrade and will be using it to explore the quantum realm. On Tuesday, Aug. 1, a major hardware update for NASA's Cold Atom Lab lifted off aboard a Northrop Grumman Cygnus resupply spacecraft on its way to the International Space Station. About the size of a small refrigerator, the lab is sometimes called the coolest place in the known universe because of its ability to chill atoms to almost absolute zero. It enables dozens of scientists on Ea ... read more
