A disk of water molecules orbiting a supermassive black hole at the core of a galaxy 60 million light-years away is reverberating in response to variations in the energy output from the galaxy’s powerful central engine close to the black hole.

Scientists have discovered the closest black hole yet, a mere 1,600 light years from Earth.

A team of astronomers has revealed tantalizing new information about the explosions of massive stars, the workings of galaxies with supermassive black holes at their centers, and clusters of galaxies.

A superfast jet of subatomic particles presumably powered by the gravitational energy of a black hole has collided with nearby material, been slowed dramatically and released much of its energy in the collision, radio astronomers report.

Astronomers using radio telescopes in New Mexico and California have discovered a giant, rotating disk of material around a young, massive star, indicating that very massive stars as well as those closer to the size of the Sun may be circled by disks from which planets are thought to form.

Researchers using the National Science Foundation’s Very Large Array radio telescope have imaged a spectacular and complex structure in a galaxy 50 million light-years away.

Astronomers using the National Science Foundation’s Very Large Array radio telescope have found previously unseen evidence that galaxy collisions trigger energetic quasar activity in relatively nearby galaxies.

Scientists and engineers at the National Radio Astronomy Observatory (NRAO) have made a giant leap toward the future of radio astronomy by successfully utilizing the Very Large Array (VLA) radio telescope in conjunction with an antenna of the continent-wide Very Long Baseline Array (VLBA) using the longest fiber-optic data link ever demonstrated in radio astronomy.

The smallest protoplanetary disk ever seen rotating around a young star has been detected by an international team of astronomers using the National Science Foundation’s Very Large Array radio telescope.

Astronomers have found evidence for the most powerful magnetic field ever seen in the universe. They found it by observing a long-sought, short-lived afterglow of subatomic particles ejected from a magnetar — a neutron star with a magnetic field billions of times stronger than any on Earth and 100 times stronger than any other previously known in the Universe.
