New multi-wavelength observations mounted by the Event Horizon Telescope (EHT) collaboration across the entire electromagnetic spectrum have provided new insight into the impact of the black hole at the core of galaxy M87 on its immediate, and not so immediate, surroundings.
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 NRAO NINE program mission is to build a pipeline of talent within the radio astronomy field, and within under-represented communities.
Milky Way-Like Galaxies in the Early UniverseAstronomers using ALMA have directly observed a pair of Milky Way-like galaxies seen as they appeared billions of years ago. These progenitors of today’s giant spiral galaxies are surrounded by "super halos" of hydrogen gas that extend many tens-of-thousands of light-years beyond their dusty, star-filled disks.

NRAO Image Contest Celebrates VLA 40th Anniversary
To help celebrate the VLA’s 40th anniversary, the National Radio Astronomy is conducting an image contest, and offering cash prizes for visually compelling works that incorporate radio observational data from the VLA.
As soon as it came online, ALMA began providing valuable information about extrasolar planetary systems at all stages of their evolution.
To balance their speeds out to those distances from their massive central cores, the galaxies must be made of more stuff than just that which we can detect.
