SuperBIT project will suspend telescope under balloon the size of a football stadium 25 miles above surface of Earth
A balloon the size of a football stadium could help astronomers get crystal-clear shots of space for a fraction of the cost of an orbital telescope like Hubble.
The secret weapon behind the SuperBIT project is a simple helium balloon – albeit one that floats up to 25 miles (40km) above the surface of the Earth and expands to a football-stadium size when fully inflated.
