True Colors of This Hot Jupiter Shine Through!

July 11, 2013, an international team of astronomers reported that the well studied exoplanet dubbed HD189733b is a beautiful blue ball dance around its star - and our own beautiful blue earth revolves around our Sun! However, this delicious blue color is about the only thing this hot Jupiter planet has in common with Earth. Hot Jupiters are giant gas planets hug their stars and rapid fire nearby, cooking miserably hot hell-like orbits - and HD189733b no exception. Astronomers believe that this hot Jupiter gets its beautiful deep blue color because silicate particles bouncing in his agitation, hazy atmosphere. This finding represents the first time that astronomers have determined the true color of an alien extrasolar planet orbiting a distant star!

True blue HD189733b was determined by astronomers using observations of the venerable Hubble Space Telescope (HST). Can we really imagine what this world would look like if we were able to watch directly, "noted Dr. Frederic Pont 11 July 2013 Press Bulletin. Imagine storms, violent anger in descending strange raindrops blown glass - fall on the side - on the surface of this planet "deep cobalt blue" swept by terrible swirling gusts of winds fire-breathing ,. This giant gas planet takes only 2.2 Earth days to travel once around your hot star, which is a "mere" 63 years-light of our solar system. This strange planet was detected 5 October 2005, when the French astronomers observed in transit across the face of its star. In fact, HD189733b star, HD189733 - alternately cataloged as V452 Vulpeculae - is a binary star system consisting of not one, but two stars. The primary star is considered a dwarf orange, while the secondary is a red dwarf. In 2007, the Spitzer infrared space telescope NASA has helped astronomers map the strange weather this bizarre alien world, when the probe produced the first map of the temperature of an exoplanet. Information Spitzer found that the temperature day and night sides of this strange world differ by about 500 degrees Fahrenheit, causing strong winds raging like a blowtorch through this hellish world. Silicates (sand material on the beautiful beaches of our world) begin to condense at temperatures climb into upper arrow to 1300 degrees Celsius, and so astronomers think they may form small glass beads in the atmosphere - which then fall as strange, hot, rain, windswept.

Using the HST, the international team of astronomers studied the visible light spectrum of this exotic extrasolar planet - one of the best studied hundreds of alien worlds discovered since 1995 this hot blue giant planet may look like the Earth from space, but our planet receives its beautiful blue hue of their beautiful lovers ocean life that absorb red and green wavelengths of light more strongly than blue. Some blue wavelengths of sunlight are also scattered by nitrogen and oxygen molecules in the atmosphere of our planet. However, cobalt blue hue HD189733b comes from the interaction of light in a hot steamy atmosphere, mixed with silicate grains in the high clouds stirred by high winds. The silicate particles melt to form glass raindrops scatter visible blue light more than red light. This alien world looks blue because of its reflected light.

Hot Jupiter Blue!

HD189733b is not Earth-analog astronomers sought - is not another pale blue dot with sparkling blue oceans love lover, foaming under a blue sky dotted with clouds marshmallow.

To determine the color of this exotic world inhospitable, the team of astronomers used what is called a secondary eclipse working on HD189773b albedo - a determination of the light that is. Just before the planet is running behind its star, astronomers can observe the starlight mixed with reflected starlight the planet. So when the planet is finally completely overshadowed by the star, astronomers can observe the light from the star itself.

Subtract the light of starlight stellar star that is mixed with the light of your planet, astronomers can detect the signature of the light reflected from the planet alone.

This clearly indicates that this hot blue alien world appears in the eyes of Earthlings.

Although the team had discovered the blue tinge of the exotic extrasolar planet by measuring the light reflected by its strange surface, the astronomers are not completely sure what causes the blue color of the planet roasting.

"It's hard to know exactly what causes the color of the atmosphere of a planet, even the planets of the solar system.
