Shockwaves resulting from the violent collision between an intruder galaxy and Stephan’s Quintet are helping astronomers to understand how turbulence influences gas in the intergalactic medium. New observations with the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Webb Space Telescope (JWST) have revealed that a sonic boom several times the size of the Milky Way has kickstarted a recycling plant for warm and cold molecular hydrogen gas. What’s more, scientists uncovered the break-up of a giant cloud into a fog of warm gas, the possible collision of two clouds forming a splash of warm gas around them, and the formation of a new galaxy. The observations were presented today in a press conference at the 241st meeting of the American Astronomical Society (AAS) in Seattle, Washington.

Five new scientific results from the Atacama Large Millimeter/submillimeter Array (ALMA), the Very Large Array (VLA), and the Green…

The design for the ngVLA prototype antenna has passed a thorough review by a panel of external experts and the project now is cleared to proceed to manufacture the prototype.

Forty-eight days after suspending observations due to a cyberattack, the Atacama Large Millimeter/submillimeter Array (ALMA) is observing the sky again. The computing staff has worked diligently to rebuild the affected JAO computer system servers and services. This is a crucial milestone in the recovery process. 

VLA teams up with Juno spacecraft to study Jupiter’s atmosphere, and ALMA reveals new details about Io’s volcanoes.
