Balloon Experimental Twin Telescope for astronomY (BETTY)

The Balloon Experimental Twin Telescope for AstronomY (BETTY) is a scientific instrument designed to study the universe by observing microwave signals from space. It is mounted on a high-altitude balloon, allowing it to float above much of Earth's atmosphere that otherwise blocks certain signals. BETTY features two telescopes working together to capture detailed images of cosmic microwave background radiation, helping scientists understand the universe's origins and structure. Its balloon platform makes it a cost-effective and flexible tool for conducting astrophysical research outside the limits of ground-based telescopes.
