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.

A Multiple-Star System Forms in Barnard 5The Barnard 5 complex of gas is in the process of becoming a multiple-star system. B5 is a molecular cloud located in the constellation Perseus, approximately 800 light-years away. It contains one young protostar and three dense condensations that astronomers say will collapse into stars in the astronomically-short period of 40,000 years. Astronomers discovered that filaments of gas in the cloud are fragmenting, and the fragments are beginning to form into additional stars that will become a multiple-star system.

Observatory Cancels Group Tours of Very Large Array and ALMA Public Visits
In order to reduce the risk of possible exposure to Coronavirus Disease 2019 (COVID-19), all group tours of the VLA are cancelled. Visitors will be able to access the visitor center, the outdoor walking tour, and the gift shop.
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.
