The Expanded Very Large Array, part of the National Radio Astronomy Observatory, took a giant step toward completion on August 7 with successful testing of advanced digital hardware designed to combine signals from its upgraded radio-telescope antennas to produce high resolution images of celestial objects.

Taking advantage of a unique cosmic coincidence, astronomers have measured an effect predicted by Albert Einstein’s theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars.

Radio-telescope images have revealed previously-unseen galactic cannibalism — a triggering event that leads to feeding frenzies by gigantic black holes at the cores of galaxies.

Scientists are using the giant Green Bank Telescope to go prospecting in a rich molecular cloud in our Milky Way Galaxy.

As NASA’s Phoenix Mars Lander descends through the Red Planet’s atmosphere toward its landing on May 25, its progress will be scrutinized by radio telescopes from the National Radio Astronomy Observatory.

Through a stroke of luck, astronomers have witnessed the first violent moments of a stellar explosion known as a supernova.
