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.

Astronomers have used the National Science Foundation’s Very Long Baseline Array radio telescope to make the first-ever time-lapse movie showing details of gas motions around a star other than our Sun.

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.
