A blue planet that rains glass has been discovered. A July 11 news release from NASA's Goddard Space Flight Center (GSFC) says that astronomers successfully used the space agency's Hubble Space Telescope to make visible-light observations of exoplanet HD 189733b. Via these observations, they came to the conclusion that the true color of the celestial body is blue. 

A deep blue planet has been found, and it is the first time such a find has been made.

The deep blue planet was found by using the Hubble telescope to find out the true color of the planet; it's the first time this has been done for a planet that circles a star other than the Sun.

The new planet is in a solar system far away from ours-but it shines a deep blue. It is a whopping 63 light years from Earth.

However, it doesn't harbor life like the pale blue planet of Earth. The deep blue planet, by contrast, is an inhospitable gas giant, where the air is often filled with glassy hail and the temperature is 1,000 degrees Celsius.

The exoplanet orbits a star (HD 189733b) 63 light-years from Earth. NASA reports that it is one of the closest exoplanets that is able to be viewed as it orbit crosses parent star.

"As far as I am aware, nobody has had actual results on the colour of an exoplanet," Frederic Pont, a researcher on the project, told press. "Now we can say that this planet is blue."

The planet was the research subject of a team from Exeter University.

Frederic Pont and his colleagues observed the deep blue planet passed behind its star. They analyzed light from the star and light reflected from the surface. Using an imaging spectrograph, they determined that blue light diminished while as the planet passed behind its star, but then brightened when it came out on the other side. "

However, while the planet may not host life, the new Hubble coloring technique may be used in the future to spot habitable planets. It can analyze cloud cover and learn about the atmospheres of planets.

"If you could see the color of an exoplanet change over time it would be very revealing. At first, the cloud cover would be the thing to go for," Pont said.

Pont hopes his research is followed by others. "Most colleagues in the field focusing on habitability concentrate on the detection of molecules in the infra-red, like water, carbon monoxide and methane," Pont said. "That's useful information of course, but my opinion is that we might be giving too much weight to this compared to visible color, which gives a different kind of information, but maybe just as crucial to understand the general state of an Earth-like planet."

While the deep blue planet may not support life, it's an incredible find-and a step toward finding habitable life.
