Three teams of scientists have used the National Science Foundation’s Very Long Baseline Array radio telescope to learn tantalizing new details about how Sun-like stars are formed.
The supersharp radio vision of the National Science Foundation’s Very Long Baseline Array is revealing unprecedented details of astronomical objects from stars in our own cosmic neighborhood to galaxies billions of light-years away.
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.
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.
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.
