The Dominion Astrophysical Observatory sits in the hills of British Columbia, Canada, and has been a key site for astronomical research in North America since the early 20th century. It houses a large optical telescope that astronomers have used for decades to study stars, galaxies, and other objects in the night sky. The site has a long history of contributions to our understanding of the universe.
ALMA is a network of radio antennas spread across the Atacama Desert in Chile, at an altitude of roughly 16,400 feet (5,000 meters). The dry air and high elevation make this one of the best places on Earth to study the universe in radio waves. Astronomers use ALMA to observe cold gas clouds, distant galaxies, and regions where new stars are forming, capturing signals that optical telescopes cannot detect.
The Very Large Telescope sits atop Cerro Paranal in the Atacama Desert in Chile, at an altitude of roughly 8,600 feet (about 2,600 meters). It is run by the European Southern Observatory and is made up of four main telescopes that can work together to observe very faint objects deep in space. The dry air and clear skies of the Atacama make this one of the most favorable spots on Earth for optical astronomy. Astronomers from around the world travel here to study distant stars, galaxies and other celestial bodies.
