ALMA Shares New View of Proxima Centauri

Proxima Centauri’s flare activity has been well known to astronomers using visible wavelengths of light, but a new study using observations with ALMA highlight this star’s extreme activity in radio and millimeter wavelengths, offering exciting insights about the particle nature of these flares as well as potential impacts to the livability of its terrestrial, habitable-zone planets.

Next-Generation Very Large Array Antenna Design to be Used By German Astronomers

Next-Generation Very Large Array Antenna Design to be Used By German Astronomers

The U.S. National Science Foundation National Radio Astronomy Observatory has announced a significant collaboration with the Bavarian State Government to construct a cutting-edge radio telescope atop Germany’s highest mountain. This radio telescope will use the design of the proposed NSF NRAO’s Next Generation Very Large Array (ngVLA).

NSF VLA Contributes Crucial Puzzle Piece to ‘Peculiar’ High Energy Transient

NSF VLA Contributes Crucial Puzzle Piece to ‘Peculiar’ High Energy Transient

High-energy transient signals are most often determined to be gamma-ray burst events, but the recently-launched Einstein Probe has expanded astronomers’ ability to quickly respond to similar signals occurring at X-ray wavelengths. Now, a multi-wavelength study of EP240408a concludes that while many of the signal’s characteristics might lead to the conclusion that it is a gamma-ray burst, the non-detection at radio wavelengths precludes that possibility.
