Atacama Large Millimeter/submillimeter Array
The Atacama Large Millimeter/submillimeter Array in the Atacama Desert, Chile, is the most complex observatory ever built.
Very Long Baseline Array
The Very Long Baseline Array (VLBA) is ten radio telescopes stationed across 5,351 miles. It’s the world’s sharpest, dedicated telescope array.
With a bit of technological help, you can capture your own amazing images of the night sky.

Tidal Disruption Event in Arp 299Artist's conception of Tidal Disruption Event (TDE) in Arp 299. Powerful gravity of supermassive black hole shreds passing star, pulling material into disk rotating around the black hole, and launching jet of particles outward. Artist's conception in pullout -- background is Hubble Space Telescope image of Arp 299, a pair of colliding galaxies.

On October 29, 2022, the Atacama Large Millimeter/submillimeter Array (ALMA) suffered a cyberattack. We are working hard to resume observations before the end of the year.
NRAO’s Marian Pospieszalski Receives EuMA Pioneer Award
The European Microwave Association (EuMA) has announced Marian Pospieszalski— a senior research engineer at the National Science Foundation’s National Radio Astronomy Observatory (NRAO)— as the recipient of its 2022 Pioneer Award. The EuMA Pioneer Award recognizes individuals responsible for noteworthy advances in the field of microwaves that have had a lasting and significant impact on the microwave community.
NRAO Expands Radio Dynamic Zone Testing with Support from NSF
Following a generous grant from the National Science Foundation’s Spectrum Innovation Initiative (SII), NSF’s National Radio Astronomy Observatory (NRAO) will expand efforts to establish and support the co-existence of research and commercial entities across the radio spectrum.
Check out our Milky Way Explorer, a guided trip through our spiral Galaxy and its neighborhood. You choose where to explore, and a radio astronomer talks to you about each stop.
Neither a hole nor really black, a stellar black hole is actually the superdense remains of a very big star that imploded, violently collapsing in on itself, during a supernova.
