SuperBIT Balloon Telescope Unveils First Set of Research Images

The Super Pressure Balloon Imaging Telescope (SuperBIT) has captured its first research images of the Tarantula Nebula and Antennae Galaxies from a balloon-borne telescope floating at 108,000 feet above Earth’s surface. Launched on a scientific super pressure balloon from Wanaka, New Zealand, the SuperBIT telescope captures images of galaxies in the visible-to-near ultraviolet light spectrum, which is within the Hubble Space Telescope’s capabilities, but with a wider field of view. The goal of the mission is to map dark matter around galaxy clusters by measuring the way these massive objects warp the space around them, also called “weak gravitational lensing.” The advantage of balloon-based versus space telescopes is the reduced cost of not having to launch a large telescope on a rocket. A super pressure balloon can circumnavigate the globe for up to 100 days to gather scientific data. The balloon also floats at an altitude above most of the Earth’s atmosphere, making it suitable for many astronomical observations. The SuperBIT team is a collaboration among NASA; Durham University, United Kingdom; the University of Toronto, Canada; and Princeton University in New Jersey.
