The first time scientists were the first to see the planet outside the solar system. According to the AP, the disposal of astronomers was the key information about distant worlds.

Both cosmic body size and structure similar to Jupiter — are made up of gas, heated to a temperature of 700 degrees Celsius. Make the discovery helped scientists orbiting telescope "Spitzer." Its sensors operate in the infrared range.

The first planet in the star catalog is registered under the number HD 209458b and is known as Osiris. It orbits a star similar to the Sun is 150 light-years from Earth in the constellation Pegasus. Characteristic infrared cosmic body was received by astronomers Goddard Space Flight Center NASA. Detailed report will appear in the scientific environment in the online version of the journal Nature.

Another planet outside the solar system discovered by a team of astronomers at the Harvard-Smithsonian Center for Astrophysics, is known as TRes-1. It is located 500 light-years from Earth in the constellation Lyra. The results of her research will be published June 20 in the journal Astrophysical Journal.

In cosmic bodies a lot in common. Both make a complete circle around the "parent" stars in less than four days and are at a distance of less than 4 million miles from the stars, which explains the high temperatures on the planets. For comparison, the Earth is rotating at 93 million miles from the Sun.

"This is an amazing discovery, we must understand that we see the light of distant worlds," — says astronomer David Charbonneau (David Charbonneau) of the Harvard-Smithsonian Center for Astrophysics.

In the mid-1990s out of the solar system were discovered more than 130 planets. They were discovered by circumstantial evidence — by gentle shaking of the trajectories of the stars and heavenly bodies by a passing diming. However, to see the world for a long time could not — the stars around which they revolve, were so far and shone so brightly that the celestial bodies were hidden from sight.
