After an odyssey of design and construction stretching across more than a decade, North America has delivered the last of the 25, 12-meter-diameter dish antennas that comprise its share of antennas for the international ALMA telescope.

Jeffrey Mangum, a scientist at the National Radio Astronomy Observatory headquarters in Charlottesville, Virginia, has been appointed Editor of the Publications of the Astronomical Society of the Pacific, a peer-reviewed scientific journal.

An unexpected discovery by astronomers using the National Science Foundation’s Very Large Array is forcing scientists to rethink their understanding of the environment in globular star clusters, tight-knit collections containing hundreds of thousands of stars.

Combining the cutting-edge capabilities of the ALMA telescope with newly-developed laboratory techniques, scientists are opening a completely new era for deciphering the chemistry of the Universe.

Two of our Milky Way’s neighbor galaxies may have had a close encounter billions of years ago, recent studies with the National Science Foundation’s Green Bank Telescope indicate.

A new observatory still under construction has given astronomers a major breakthrough in understanding a nearby planetary system that can provide valuable clues about how such systems form and evolve.
