A team of astronomers says that observations with the National Science Foundation’s Very Large Array radio telescope show that a neighboring bloated star has giant convective plumes propelling gas from its surface up into the star’s atmosphere.

A team of astronomers using a pair of National Science Foundation radio telescopes has made the first measurements of the size and expansion of a mysterious, intense fireball resulting from a cosmic gamma ray burst last May.

Marking an important new milestone in radio astronomy history, scientists at the National Radio Astronomy Observatory in Socorro, New Mexico, have made the first images using a radio telescope antenna in space.

Radio astronomers revealed that the first gamma-ray burster ever detected at radio wavelengths has surprised them by its erratic behavior.

New observations with the National Science Foundation’s Very Long Baseline Array indicate that the inner workings of active galaxies may be considerably more complex than astronomers have previously thought.

Astronomers at the National Radio Astronomy Observatory have used the continent-wide Very Long Baseline Array to map for the first time the magnetic field on the surface of a star other than the Sun.
