Gravity can change the path of light, and sometimes focuses the light of distant galaxies to create a gravitational lens or Einstein Ring. It is a common sight in modern deep field images, but the effect was first seen by the Very Large Array in 1987.
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.
Black Holes are strange creatures. They are objects so dense that light cannot escape them. Since black holes don’t…

Sharper Image of Galaxy with VLASSThe sharpest radio view ever made of such a large portion of the sky! This galaxy, observed by the new VLA Sky Survey, resides near the constellation Draco in the northern hemisphere. No sources are detected at the radio galaxy's position in optical wavelengths (center right panel), but there is a hint of the central galaxy at infrared wavelengths (bottom right panel). The top right panel shows the radio source from our previous (NVSS) survey, but the resolution was too faint to work out the details. However, our new survey has the resolution to reveal the distinct features of the radio lobes from a supermassive black hole found at the heart of most galaxies!

Announcements and Achievements
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.
NRAO Mission Statement Update Reflects and Strengthens Observatory’s Long-standing Commitment to DEI
NSF’s National Radio Astronomy Observatory (NRAO) has announced major updates to its organizational mission statement that are reflective of the Observatory’s long-standing commitment to diversity, equity, and inclusion in astrophysics.
NRAO’s Gurton Receives Astronomical Society of the Pacific Award
Suzanne (Suzy) Gurton, NRAO’s Assistant Director for Education and Public Outreach, has been named the 2022 recipient of the Astronomical Society of the Pacific’s prestigious Klumpke-Roberts Award. The award recognizes outstanding contributions to the public understanding and appreciation of astronomy.
On a clear, dark night, you can see a glowing stream that seems to split the sky. We have called it the Milky Way for thousands of years, and its exact nature was a mystery until less than a hundred years ago.
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.
