Young Stars Shape the Fate of Galaxies
A team of astronomers found that in typical galaxies, pressure from ionized gas generated by newly formed stars drives the expansion of star-forming regions. However, whether these regions continue to grow or stall depends strongly on their surrounding environment.
NSF VLA and ALMA Reveal Hidden “Ring Factories” of Giant Star Clusters in Nearby Galaxies
Astronomers have used U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO) radio telescopes in Chile and New Mexico to peer through cosmic smoke and haze, building one of the clearest pictures yet of how giant clusters of young stars are born in the hearts of nearby galaxies.

A black hole has blasted out a surprisingly powerful jet in the distant universe, according to a new study from NASA’s Chandra X-ray Observatory. This jet exists early enough in the cosmos that it is being illuminated by the leftover glow from the big bang itself.
Astronomers used Chandra and the U.S. National Science Foundation Karl G. Jansky Very Large Array (NSF VLA) to study this black hole and its jet at a period they call “cosmic noon,” which occurred about three billion years after the universe began. During this time most galaxies and supermassive black holes were growing faster than at any other time during the history of the universe.
Scientists can use this jet to probe questions about how black holes helped shape their surroundings during this critical era in cosmic history. This science was presented at the 246th American Astronomical Society Conference in Anchorage, Alaska on Monday, June 9, 2025, 10:15 AM AK. You can read the full release from Chandra.
