The process of returning ALMA to operational status has begun by powering up the first few antennas for the first time since the COVID-19 shutdown in March of 2021.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), along with other telescopes, have discovered the most distant quasar yet found. The bright quasar, powered by a supermassive black hole at the core of a galaxy, is seen as it was only 670 million years after the Big Bang, and is providing valuable clues about how such huge black holes and their host galaxies formed in the early Universe.
Observations with the continent-wide Very Long Baseline Array (VLBA) reveal previously unseen details in a jet of material ejected from the core of a galaxy seen as it was when the universe was only about 7 percent of its current age.
NRAO and GBO are saddened at the announcement of the decommissioning of the Arecibo Telescope in Puerto Rico, which has a long and distinguished history of scientific accomplishment.
Comparing data from VLA sky surveys made some two decades apart revealed that the black hole-powered “engines” at the cores of some distant galaxies have launched new, superfast jets of material during the interval between the surveys.
New VLA images show how the crowded environment of a cluster of galaxies affects the individual galaxies, helping astronomers better understand some of the complex details of such an environment.
The Very Large Array Sky Survey (VLASS) is an ambitious project to make a high-resolution radio map of nearly…
ALMA telescope conducts largest survey yet of distant galaxies in the early universe
New radio images from ALMA show for the first time the direct effect of volcanic activity on the atmosphere of Jupiter’s moon Io.
Join our host Melissa Hoffman as she talks about the history of the VLA and some of the remarkable objects it has discovered!
