Hubble finds blue planet with glass rain

In a world first astronomers have been able to determine the true colour of an extrasolar planet.

At a distance of 63 light years, the planet HD189733b possesses a deep azure colour that might at first glimpse seem like an indication that it is very similar to the Earth. Far from being a water-rich haven however, the new planet is a gas giant with an atmosphere of 1,000 degrees Celsius and winds up to 7,000km per hour. This distant world is even pelted by searing glass shards raining down from the heavens.

"Measuring its colour is a real first - we can actually imagine what this planet would look like if we were able to look at it directly," said Professor Frederic Pont. To do this, astronomers observed the changes in the light spectrum from the host star when the planet passed behind it.

"For the first time, astronomers have determined the true colour of a planet orbiting another star."

The new prince song will be "Azure Rain", the follow up to his 80's classic "purple rain". Just sayin'.

Awesome indeed, but not one where you would want to be caught in a storm, lol.

I think you are getting your space telescopes mixed up. It is Kepler that has the problems, Hubble is in perfect working order.

I stand corrected. Thank you! Knew it was one of those space telescopes.

Actually it was Jacques Terreur that said he thought it was broken.

i heard it in a german radio broadcast, they stated clearly that it was Hubble that broke, some weeks ago.....oh well, what sources can you trust these days, eh? Very exciting finds anyway!
