Call it the deep blue dot. For the first time, scientists have seen the visible color of a distant alien world. The exoplanet — called HD 189733b — is 63 light-years from Earth and a “deep cobalt blue,” with raging storms of glass rain and super-fast winds, scientists say.

The alien planet’s blue color was pinned down using observations from the Hubble Space Telescope. Although the planet might be the same color as Earth from space, scientists think that HD 189733b is a “hot Jupiter” — a gas giant planet that orbits very close to its star. It takes 2.2 Earth days for the planet to travel fully around its sun.

“This planet has been studied well in the past, both by ourselves and other teams,” said Frédéric Pont of the University of Exeter, U.K., leader of the Hubble observing program in a statement. “But measuring its color is a real first — we can actually imagine what this planet would look like if we were able to look at it directly.”[See More Images of the Blue Alien Planet HD 189733b]

The exoplanet’s weather is less than ideal. Its atmosphere is more than 1,832 degrees Fahrenheit (1,000 degrees Celsius) and the planet rains glass sideways in 4,350 mile per hour (7,000 km/h) winds, according to Hubble officials.
