VLA Discovers Powerful Jet Coming from “Wrong” Kind of Star
September 26, 2018 at 1:00 pm | News Release

The VLA’s discovery of a jet of material launched from a highly-magnetic neutron star has forced rethinking a longstanding theory.

VLBA Measures Asteroid’s Characteristics
September 13, 2018 at 9:59 am | News Release

Astronomers used the VLBA in an unusual way to learn new details about an asteroid’s size, shape, and orbit.

Fierce Winds Quench Wildfire-like Starbirth in Far-flung Galaxy
September 6, 2018 at 2:00 pm | News Release

Astronomers using ALMA, with the aid of a gravitational lens, have detected the most-distant galactic “wind” of molecules ever observed, seen when the universe was only one billion years old. By tracing the outflow of hydroxyl (OH) molecules – which herald the presence of star-forming gas in galaxies – the researchers show how some galaxies in the early universe quenched an ongoing wildfire of starbirth.

Radio Observations Confirm Superfast Jet of Material From Neutron Star Merger
Radio Observations Confirm Superfast Jet of Material From Neutron Star Merger
September 5, 2018 at 1:00 pm | News Release

The super-sharp radio “vision” of a continent-wide collection of NSF radio telescopes answered an outstanding question about the aftermath of the merger of two neutron stars.

First Science with ALMA’s Highest-Frequency Capabilities
August 17, 2018 at 11:00 am | News Release

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.

Observatory Receives Funds to Repair St. Croix Radio Telescope
August 7, 2018 at 1:26 pm | News Release

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.

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.

VLA Gives Tantalizing Clues About Source of Energetic Cosmic Neutrino
July 12, 2018 at 11:00 am | News Release

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.
