NASA Hubble Finds a True Blue Planet


www.nasa.gov said:

Astronomers making visible-light observations with NASA's Hubble Space Telescope have deduced the actual color of a planet orbiting another star 63 light-years away.

The planet is HD 189733b, one of the closest exoplanets that can be seen crossing the face of its star.

Hubble's Space Telescope Imaging Spectrograph measured changes in the color of light from the planet before, during and after a pass behind its star. There was a small drop in light and a slight change in the color of the light. "We saw the light becoming less bright in the blue but not in the green or red. Light was missing in the blue but not in the red when it was hidden," said research team member Frederic Pont of the University of Exeter in South West England. "This means that the object that disappeared was blue."

A gas planet similar to Neptune perhaps?...

I wonder what Earth would look like - blue mostly I'm sure...

The variety of the exoplanets, and for that matter, our own solar system's planets and moons never ceases to amaze. The sad thing is that we may one day find a "perfect" analog to earth orbiting another star but it may be that it is not possible to ever reach it physically.

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

A planet that may rain liquid glass, my oh my, what other wonders does the universe hold for u??s. Would love to be an Astronaut in orbit around this planet so as to study it more. Amazing.

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.
