An artist's impression of the extrasolar planet HD 189733b seen here with its parent star looming behind. The planet is slightly larger than our own Solar System's Jupiter. Its atmosphere is a scorching eight hundred degrees Celsius. Astronomers using data collected with Hubble's ACS instrument have found that the sunset on HD 189733b would look similar to a hazy red sunset on Earth due to high level hazes in the planet's atmosphere.
