Band 10, ALMA’s highest frequency vision, has given scientists a new view of jets of warm water vapor streaming away from a newly forming star and uncovered an astonishing assortment of molecules.

The National Science Foundation has provided funding to repair damage to the Very Long Baseline Array station on St. Croix caused by Hurricane Maria in 2017.

Astronomers have used the VLA to detect a possible planetary-mass object with a surprisingly powerful magnetic field some 20 light-years from Earth. It can help scientists better understand magnetic processes on stars and planets.

Astronomers have made the first definitive detection of a radioactive molecule in interstellar space: a form, or isotopologue of aluminum monofluoride. The new data reveal that this radioactive isotopologue was created by the collision of two stars, a tremendously rare cosmic event that was witnessed on Earth as a “new star,” or nova, in the year 1670.

Astronomers using ALMA studied a cataclysmic stellar explosion known as a gamma-ray burst, or GRB, and found its enduring “afterglow.” The rebound, or reverse shock, triggered by the GRB’s powerful jets slamming into surrounding debris, lasted thousands of times longer than expected.

The track of an elusive, energetic neutrino points to a distant galaxy as its source and VLA observations suggest high-energy particles may be generated in superfast jets of material near the galaxy’s core.
