Astronomers have discovered the strongest evidence yet found indicating that matter is being ejected by a medium-sized black hole, providing valuable insight on a process that may have been key to the development of larger black holes in the early Universe.

New, high-precision distance measurements by the National Science Foundation’s Very Long Baseline Array (VLBA) radio telescope are providing a major advance for astronomers trying to understand how stars form.

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.

The National Science Foundation’s Astronomy Senior Review Committee report, released today, made major recommendations for restructuring the NSF’s ground-based astronomy efforts, including significant changes for the National Radio Astronomy Observatory.

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.
