Washington, August 10 (ANI): NASA’s new exoplanet-hunting Kepler space telescope has detected the atmosphere of a known giant gas planet.

The find is based on a relatively short 10 days of test data collected before the official start of science operations.

Kepler was launched on March 6, 2009, from Cape Canaveral Air Force Station in Florida.

“As NASA’s first exoplanets mission, Kepler has made a dramatic entrance on the planet-hunting scene,” said Jon Morse, director of the Science Mission Directorate’s Astrophysics Division at NASA Headquarters in Washington.

“Detecting this planet’s atmosphere in just the first 10 days of data is only a taste of things to come. The planet hunt is on,” he added.

“When the light curves from tens of thousands of stars were shown to the Kepler science team, everyone was awed; no one had ever seen such exquisitely detailed measurements of the light variations of so many different types of stars,” said William Borucki, the principal science investigator.

The observations were collected from a planet called HAT-P-7, known to transit a star located about 1,000 light years from Earth.

The planet orbits the star in just 2.2 days and is 26 times closer than Earth is to the sun.

Its orbit, combined with a mass somewhat larger than the planet Jupiter, classifies this planet as a “hot Jupiter.”

It is so close to its star, the planet is as hot as the glowing red heating element on a stove.

The new Kepler data can be used to study this hot Jupiter in unprecedented detail.

The depth of the occultation and the shape and amplitude of the light curve show the planet has an atmosphere with a day-side temperature of about 4,310 degrees Fahrenheit.

Little of this heat is carried to the cool night side. The occultation time compared to the main transit time shows the planet has a circular orbit.

The discovery of light from this planet confirms the predictions by researchers and theoretical models that the emission would be detectable by Kepler.

This new discovery also demonstrates Kepler has the precision to find Earth-size planets.

Kepler will spend the next three-and-a-half years searching for planets as small as Earth, including those that orbit stars in a warm zone where there could be water.

It will do this by looking for periodic dips in the brightness of stars, which occur when orbiting planets transit, or cross in front of, the stars. (ANI)
