Astronomers found a blue planet, 63 light years away, that is 2,000 degrees Fahrenheit and rains glass

Researchers found that one of the closest
planets to our solar system also shares
the Earth's blue coloring, according to
recent observations from NASA's Hubble
Space Telescope.

But the mutual blue hue is about all the
two planets have in common. This planet,
HD 189733b, is about 63 light years away
from Earth, and is about the same size as
Jupiter, the largest planet in the solar
system. Its "turbulent alien world" has
temperatures that approach 2,000 degrees
Fahrenheit during the daytime, roaring
winds of up to 4,500 mph and glass that
rains sideways, according to a NASA
statement.
The planet is among a class called "hot
Jupiters," which orbit very close to their
parent stars. Astronomers first discovered
the planet in 2005, but have only recently
been able to use the telescope to
determine its color. Their findings are
detailed in an upcoming issue of The
Astrophysical Journal Letters.
"It's very different from the planets in our
solar system," said lead researcher Tom
Evans, of the University of Oxford, in a
statement.
Because HD 189733b orbits so close to its
parent star – about 2.9 million miles – it is
locked gravitationally. That means one
side of the planet is always in the dark.
Because of that proximity, the planet
reaches extremely high temperatures and
is "bombarded with massive amounts of
radiation," Evans said in the statement.

Mercury is the closest planet in the
Earth's solar system to the sun, at about
29 million miles away, CNN reports .
The group of researchers used the
telescope's imaging spectrograph to
measure the changes in the color of light
the planet emanated as it passed behind
the star.
"We saw the light becoming less bright in
the blue but not in the green or red," said
University of Exeter researcher Frederic
Pont, in a statement. "Light was missing
in the blue but not in the red when it was
hidden. This means that the object that
disappeared was blue."
The team of researchers believes that
knowing the color of the planet may lead
to new discoveries about its chemical
composition and cloud structure.

But unlike the Earth, which gets its color
from the reflection of large bodies of
water, this planet's coloring comes from a
"hazy, blow-torched atmosphere" and bits
of glass that rain down in the fierce winds
across the planet. These shards are
formed by particles that condense in heat
and have a tendency to scatter blue light
more than red light, according to the
report.
Determining the cloud composition of this
planet could shed light on information
about the entire class of hot Jupiters,
NASA said, because clouds "often play key
roles in planetary atmospheres."
