VLA Detects Possible Extrasolar Planetary-Mass Magnetic Powerhouse
August 2, 2018 at 6:33 pm | News Release

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.

Pair of Colliding Stars Spill Radioactive Molecules into Space
July 30, 2018 at 11:00 am | News Release

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.

Enduring ‘Radio Rebound’ Powered by Jets from Gamma-Ray Burst
July 26, 2018 at 11:00 am | News Release

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.
