An extraordinary cosmic laboratory 21 million light-years away is providing radio astronomers their best opportunity yet to decipher the mysteries of the ultra-powerful engines at the hearts of many galaxies and quasars.

A VLA upgrade proposes an essentially new instrument, created from two existing instruments, with power and capability far exceeding that of either one alone.

Observations of Comet Hyakutake with the National Science Foundation’s millimeter-wave radio telescope in Arizona have revealed new information about our Solar System’s original material, including the first detection of the Carbonyl Sulfide  molecule in a comet.

Do nearby stars have planetary systems like our own? How do such systems evolve? How common are such systems? Proposed radio observatories operating at millimeter wavelengths could start answering these questions within the next 6-10 years, according to scientists at the National Radio Astronomy Observatory.

Astronomers using the Very Large Array radio telescope have found some of the best evidence to date that small, new galaxies can form from material pulled out of older galaxies.

Astronomers using an international network of radio telescopes have produced a movie showing details of the expansion of debris from an exploding star.
