The William Gordon Telescope is a radio telescope at the Arecibo Observatory in Puerto Rico. It was built in 1963 and is used to study radio astronomy and atmospheric science. At 1,000 feet, it’s the world’s largest single-aperture RADIO telescope.

The Sloan Sky Digital Telescope sits at the Apache Point Observatory in New Mexico. It has completed some of the most detailed 3D maps of the universe ever made.

The Major Atmospheric Gamma Imaging Cherenkov, known as MAGIC, is two gamma ray telescopes. Each has a mirror surface of 2,540 square feet. It studies active galactic nuclei, black hole binary systems and supernova remnants.

The photographer took this image looking up at the sky from inside the main reflector mirror of the Hobby-Eberly Telescope at the McDonald Observatory in West Texas. The telescope is used in the Hobby-Eberly Telescope Dark Energy Experiment to search for dark energy.

Japan’s Subaru optical telescope is located on Mauna Kea in Hawaii. It has one of the largest monolithic primary mirrors in the world, spanning 27 feet.

The Keck II telescope in Hawaii pioneered the use of lasers in telescopes. It uses a sodium dye laser that charges sodium atoms from left behind by meteors. That makes them light up, creating a fake star that helps astronomers better correct for visual distortions in the earth’s atmosphere.

ALMA, the world’s most powerful radio telescope, sits in the Atacama Desert in northern Chile.

The Large Binocular Telescope in Arizona has two 27-foot mirrors that look like eyes.

The Large Binocular Telescope is an optical telescope sitting at an eleavation of 10,700 feet atop Mount Graham in Arizona.
