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.
Rotating Disk around Young, Massive Star
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.
Movie Star Acting Strangely, Radio Astronomers Find
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.
Spectacular Structure in Distant Galaxy
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.
Nearby Quasars Come From Galactic Encounters
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.
Elongated Radio-Emitting Region in Center of Milky Way
For the first time, astronomers have determined the intrinsic size and shape of the highly charged region of radio emission surrounding what most scientists believe to be a supermassive black hole at the center of our own Milky Way Galaxy.
