The Universe is a dynamic and exciting place, with stars, planets, and galaxies being born, dying, and undergoing dramatic changes. In 2022, the telescopes of the National Science Foundation’s National Radio Astronomy Observatory (NRAO) revealed fascinating new details about several of these processes, and we’re giving you a taste of the greatest radio astronomy moments of the year.
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.

Finding Ice in Baby Solar SystemsArtist concept of the so-called "snow line" in the young planet-forming system known as TW Hydrae. A snow line is where particles become icy and can more easily stick together to make larger chunks when they collide. This is one way for planets to form. ALMA has found water-covered ice grains in this system's inner disk (4.5 -- 30 AU, blue) and carbon monoxide (CO) ice-covered grains in the outer disk (>30 AU, green). The transition from blue to green marks the CO snow line.

Announcements and Achievements
NSF and SpaceX Finalize Radio Spectrum Coordination Agreement
The National Science Foundation (NSF) and SpaceX have finalized a radio spectrum coordination agreement to limit interference from the company’s Starlink satellites to radio astronomy assets operating between 10.6 and 10.7 GHz. The agreement, detailed in a .statement released by NSF today, ensures that Starlink satellite network plans will meet international radio astronomy protection standards, and protect NSF-funded radio astronomy facilities, including the National Radio Astronomy Observatory (NRAO) and the Green Bank Observatory (GBO). The agreement will also positively impact collaborations and cooperation between SpaceX and NSF’s NOIRLab.
Science Results From NRAO Facilities to Be Presented at Multiple AAS 241 Press Conferences
Five new scientific results from the Atacama Large Millimeter/submillimeter Array (ALMA), the Very Large Array (VLA), and the Green…
Design Review for ngVLA Antenna Clears Way for Prototype Construction
The design for the ngVLA prototype antenna has passed a thorough review by a panel of external experts and the project now is cleared to proceed to manufacture the prototype.
ALMA Has Successfully Restarted Observations
Forty-eight days after suspending observations due to a cyberattack, the Atacama Large Millimeter/submillimeter Array (ALMA) is observing the sky again. The computing staff has worked diligently to rebuild the affected JAO computer system servers and services. This is a crucial milestone in the recovery process.
A galaxy is an island of stars floating on a plate of dark matter, or so the theory goes.
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.
