Astronomers have gained their first glimpse of the mysterious region near a black hole at the heart of a distant galaxy, where a powerful stream of subatomic particles spewing outward at nearly the speed of light is formed into a beam, or jet, that then goes nearly straight for thousands of light-years.

Two hundred astronomers from around the world will meet in Washington, DC on October 7 and 8 to discuss exciting new science to be done with the Atacama Large Millimeter Array (ALMA).

A team of radio astronomers has used the National Science Foundation’s Very Long Baseline Array (VLBA) to make the most accurate measurement ever made of the distance to a faraway galaxy.

Astronomers using the National Science Foundation’s powerful Very Long Baseline Array radio telescope have made a new and more accurate determination of just how long it takes us to circle our Galaxy — 226 million years.

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.
