Data from Hubble and Spitzer telescopes gives clues to planet’s formation
The atmosphere of a recently discovered Neptune-sized planet in our galaxy has been shown to contain water – a finding revealed by the Hubble and Spitzer space telescopes. The planet – called HAT-P-26b – is about the size of the gas giants Neptune and Uranus, and is orbiting another star around 450 light years away from our solar system. It was discovered in 2010 but the composition of its atmosphere remained elusive.
