Neutron Stars Strike Back at Black Holes in Jet Contest
August 4, 2015 at 6:00 am | News Release

Some neutron stars may rival black holes in their ability to accelerate powerful jets of material to nearly the speed of light.

Astronomers Discover Powerful Aurora Beyond Solar System
July 29, 2015 at 5:00 pm | News Release

Astronomers have discovered the first aurora ever seen in an object beyond our Solar System. The aurora, similar to the famous “Northern Lights” on Earth, is 10,000 times more powerful than any previously seen.

Brown Dwarfs, Stars Share Formation Process, New Study Indicates
July 23, 2015 at 3:51 pm | News Release

Astronomers using the Very Large Array have discovered jets of material ejected by still-forming young brown dwarfs.

Magnetic-Field Discovery Gives Clues to Galaxy Formation Processes
June 18, 2015 at 2:00 pm | News Release

Astronomers making a detailed, multi-telescope study of a nearby galaxy have discovered a magnetic field coiled around the galaxy’s main spiral arm.

VLA Reveals Bashful Black Hole in Neighboring Galaxy
June 17, 2015 at 3:45 pm | News Release

Thanks to the extraordinary sensitivity of the Karl G Jansky Very Large Array (VLA), astronomers have detected what they believe is the long-sought radio emission coming from a supermassive black hole at the center of one of our closest neighboring galaxies.

Strange Supernova is ‘Missing Link’ in Gamma-Ray Burst Connection
April 27, 2015 at 4:52 pm | News Release

Astronomers using the National Science Foundation’s Very Large Array (VLA) have found a long-sought ‘missing link’ between supernova explosions that generate gamma-ray bursts (GRBs) and those that don’t. The scientists found that a stellar explosion seen in 2012 has many characteristics expected of one that generates a powerful burst of gamma rays, yet no such burst occurred.

Astronomers Watch Unfolding Saga of Massive Star Formation
April 2, 2015 at 6:00 pm | News Release

A pair of images of a young star, made 18 years apart, has revealed a dramatic difference that is providing astronomers with a unique, ‘real-time’ look at how massive stars develop in the earliest stages of their formation.

Image Release: Mysterious Phenomena in a Gigantic Galaxy-Cluster Collision
March 10, 2015 at 12:00 pm | News Release

Researchers using the Karl G. Jansky Very Large Array (VLA) have produced the most detailed image yet of a fascinating region where clusters of hundreds of galaxies are colliding, creating a rich variety of mysterious phenomena visible only to radio telescopes.

Astronomers Catch Multiple-Star System in First Stages of Formation
February 11, 2015 at 6:00 pm | News Release

For the first time, astronomers have caught a multiple-star system in the beginning stages of its formation, and their direct observations of this process give strong support to one of several suggested pathways to producing such systems.
