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.

First Fringes of ALMA PrototypesIn March of 2007, two ALMA prototype antennas were linked together at the Very Large Array in New Mexico as an integrated system to observe a celestial object. Faint radio waves emitted by the planet Saturn were collected by these two ALMA antennas, then processed by new, state-of-the-art electronics to turn the antennas into a single, high-resolution telescope system, called an interferometer. Such pairs of antennas are the basic building blocks of multi-antenna imaging systems such as ALMA and the VLA. In such a system, each antenna is combined electronically with every other antenna to form a multitude of pairs. Each pair contributes unique information that is used to build a highly-detailed image of the astronomical object under observation.

NRAO’s Brett McGuire Part of Science News 10: Scientists to Watch
Dr. Brett McGuire of the National Radio Astronomy Observatory (NRAO) has been named to Science News’ list of 10 early-and mid-career scientists on their way to greater widespread acclaim.
First Canadian ALMA Large Program to Investigate the Impact of Galaxy Environment on Star Formation
The first ever Canadian-led Atacama Large Millimeter/submillimeter Array (ALMA) Large Program has been approved for cycle 7. Dr. Brown and his colleagues will use the Atacama Compact Array (ACA) to study the influence of galaxy environment on star formation in the Virgo Cluster.
Dosvedanya and Farewell, RadioAstron
On May 30, 2019, the Russian RadioAstron satellite — the farthest element of an Earth-to-space radio-telescope system — ended its service.
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!
From the Earth, a pulsar looks like a star that has a pulse, a rapid beat picked up only by radio telescopes.
