Astronomers have used the National Science Foundation’s Very Large Array radio telescope to image a young, multiple-star system with unprecedented detail, yielding important clues about how such systems are formed.

Astronomers using the National Science Foundation’s Very Large Array radio telescope have discovered giant, ring-like structures around a cluster of galaxies.

A striking image of an enormous bubble blown into the dusty gas disk of our own Milky Way galaxy has won first place in the National Radio Astronomy Observatory’s second annual Radio Astronomy Image Contest.

A cosmic explosion seen last February may have been the tip of an iceberg” showing that powerful, distant gamma ray bursts are outnumbered ten-to-one by less-energetic cousins, according to an international team of astronomers.

Astronomers using the National Science Foundation’s Very Large Array (VLA) radio telescope have discovered key evidence that may help them figure out how very massive stars can form.

Astronomers using radio telescopes from around the world have discovered a spinning neutron star with a superpowerful magnetic field — called a magnetar — doing things no magnetar has been seen to do before.

Astronomers studying a disk of material circling a still-forming star inside our Galaxy have found a tantalizing result — the inner part of the disk is orbiting the protostar in the opposite direction from the outer part of the disk.

Astronomers have found a relatively tiny galaxy whose black-hole-powered central engine is pouring out energy at a rate equal to that of much larger galaxies, and they’re wondering how it manages to do so.

Interstellar travelers might want to detour around the star system TW Hydrae to avoid a messy planetary construction site.

Forget the headphones you saw in the Warner Brothers thriller Contact, as well as the guttural throbs emanating from loudspeakers at the Very Large Array in that 1997 movie.
