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 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 Tarantula Nebula is a large star-forming region of ionized hydrogen gas that lies 161,000 light-years from Earth in the Large Magellanic Cloud, and its turbulent clouds of gas and dust appear to swirl between the region's bright, newly formed stars. The Tarantula Nebula has previously be captured by both the Hubble Space Telescope and James Webb Space Telescope.
The Antennae galaxies, cataloged as NGC 4038 and NGC 4039, are two large galaxies colliding 60 million light-years away toward the southerly constellation Corvus. The galaxies have previously been captured by the Hubble Space Telescope, Chandra X-ray Observatory, and now-retired Spitzer Space Telescope. A composite image of the galaxies combines data taken by all three telescopes.
SuperBIT's first research images from this flight were released by Durham University here. The SuperBIT team is a collaboration among NASA; Durham University, United Kingdom; the University of Toronto, Canada; and Princeton University in New Jersey.
