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.

The Dawn of a New Era for Supernova 1987AAstronomers combined observations from three different observatories to produce this colorful, multiwavelength image of the intricate remains of Supernova 1987A.The red color shows newly formed dust in the center of the supernova remnant, taken at submillimeter wavelengths by the Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile.The green and blue hues reveal where the expanding shock wave from the exploded star is colliding with a ring of material around the supernova. The green represents the glow of visible light, captured by NASA's Hubble Space Telescope. The blue color reveals the hottest gas and is based on data from NASA's Chandra X-ray Observatory.The ring was initially made to glow by the flash of light from the original explosion. Over subsequent years the ring material has brightened considerably as the explosion's shock wave slams into it.Supernova 1987A resides 163,000 light-years away in the Large Magellanic Cloud, where a firestorm of star birth is taking place.The ALMA, Hubble, and Chandra images at the bottom of the graphic were used to make up the multiwavelength view.

Book Release: “Joe Pawsey and the Founding of Australian Radio Astronomy”
This book was more than 15 years in the making, and it is a collaboration of three authors across two continents who worked together to bring to light the story of Joe Pawsey, a key figure in Australian science and, especially, radio astronomy.
$21 Million NSF Award Will Bring ngVLA Design to Life
The largest astronomical array in North America is one step closer to becoming a reality. The National Radio Astronomy Observatory (NRAO) is pleased to announce that the National Science Foundation (NSF) has awarded a 3-year, $21 million grant to Associated Universities, Inc.(AUI) to further the design of the next generation Very Large Array (ngVLA).
NRAO First Wave Completed 20 Weeks of Amateur Radio Learning Program for BIPOC and LGBTQIA+ Learners
Following a grant from Amateur Radio Digital Communications (ARDC), the National Science Foundation‘s (NSF’s) National Radio Astronomy Observatory (NRAO) launched a two-year project to engage BIPOC and LGBTQIA+ learners in learning about the electromagnetic spectrum and discovering the excitement of ham radio. The project, Exploring the Electromagnetic Spectrum (EMS) with Amateur Radio, offered its first learner-facing training in January 2023.
Hear from folks who work at NRAO about the many paths we’ve taken to get here. You don’t have to be a scientist or engineer to be part of our exciting mission!
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.
