Astronomers first observed from the Earth's atmosphere extrasolar planets

Today, two teams of scientists published a report published for the first time detected in Earth's atmosphere of extrasolar planets results of the study.

Extrasolar planets are orbiting a star other than the Earth's solar system functioning, it is difficult to detect the stars, the two reports were published, for the study of extrasolar planets has opened up a territory of Xinjiang.

Has been detected extrasolar planets almost 300, but astronomers think that there are more to be explored, some of which extrasolar planets, so that the Earth may have had similar conditions for the birth.

So far, the atmosphere on extrasolar planets understanding, almost all "Edwards Spiegel" (Spitzer) Infrared Space Telescope collected.

But Spiegel is used to allow the telescope to maintain cooling equipment refrigerant will soon be used up to a serious limited observation capabilities.

The report published today a group of team detected that the Earth is several times the size of large planets "OGLE-TR-56b", which is a so-called "hot Jupiters" (hot Jupiter).

Hot Jupiter orbits very close to their stars, they are very close, it is believed that their temperature, sufficient to be released from the Earth's point of view, to optical wavelength with the near-infrared wavelength radiation distributed.

Carnegie Institute of Washington (Carnegie Institution) the Morales (Mercedes Lozez-Morales) said: "The secret of success is: release a lot of planetary heat, the atmosphere is almost no wind."

In addition, the Earth must also be clear calm night, in order to run the Department of extrasolar planets to their stars behind the emergence of eclipse phase, the correct estimate of the difference in their heat.

Last summer, two scientists observing OGLE-TR-56b, one of which used the European Southern Observatory (Euroean Southern Observatory) of the "Very Large Telescope" (Very Large Telescope), the first use of the Carnegie Endowment for their own "Lombard" (Magellan-Baade ) telescopes, two telescopes are installed in Chile.

Dutch astronomer in a separate also published in Paris, "Astronomy and Astrophysics" (Astronomy and Astrophysics) Journal study, published detected an exoplanet another "TrES-3b" distributed energy report.
