Hubble Finds a True Blue Planet: Giant Jupiter-Sized Planet Located 63 Light-Years Away
July 11, 2013 — Astronomers using NASA’s Hubble Space Telescope have deduced the actual visible-light color of a planet orbiting another star 63 light-years away.
If seen directly it would look like a “deep blue dot,” reminiscent of Earth’s color as seen from space. But that’s where all comparison ends. The planet’s daytime atmosphere is nearly 2,000 degrees Fahrenheit, and it possibly rains glass — sideways — in howling 4,500-mile-per-hour winds.
