The record-setting close approach of an asteroid on February 15 is an exciting opportunity for scientists, and a research team will use National Radio Astronomy Observatory and NASA telescopes to gain a key clue that will help them predict the future path of this nearby cosmic neighbor.

A new view of a 20,000-year old supernova remnant demonstrates the upgraded imaging power of the National Science Foundation’s Very Large Array and provides more clues to the history of this giant cloud that resembles a beloved endangered species, the Florida Manatee.

Astronomers have discovered hundreds of previously-unknown sites of massive star formation in the Milky Way, including the most distant such objects yet found in our home Galaxy.

The surprising discovery of a massive outburst in a neighboring galaxy is giving astronomers a tantalizing look at what likely is a powerful belch by a gorging black hole at the galaxy’s center.

Astronomers have used the ALMA telescope to get their first glimpse of a fascinating stage of star formation in which planets forming around a young star are helping the star itself continue to grow, resolving a longstanding mystery.

One of the most powerful calculating machines known to the civilian world has been installed and tested in a remote, high-altitude site in the Andes Mountains of northern Chile, marking one of the major remaining milestones toward completion of the most elaborate ground-based telescope in history, the Atacama Large Millimeter/submillimeter Array.
