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

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
