Astronomers have made a significant step toward confirming a proposed explanation for how solar flares accelerate charged particles to speeds nearly that of light.

A study of spiral galaxies seen edge-on has revealed that “halos” of cosmic rays and magnetic fields above and below the galaxies’ disks are much more common than previously thought.

There may be fewer pairs of supermassive black holes orbiting each other at the cores of giant galaxies than previously thought.

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

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.

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

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

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.

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.

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.
