corot surprises everyone with an exoplanet

corot

The European COROT satellite has the first images of a large planet beyond our solar system to another star rotates, and the first seismic data of the sun-like star with unexpected precision sent to earth.These good results show that the COROT is able to see rocky planets, even planets as small as Earth, and possibly the chemical composition of the planet reveal.COROT, a project of the French space agency CNES in cooperation with ESA, is a mission with a dual mission. The first goal of the mission is to find planets outside our solar system (exoplanets). It delves into a wide area to planets like ours with unprecedented precision.It also makes the most comprehensive study ever into the interior of stars other than our Sun. Both studies were made possible by the measurement of changes in the emitted light of the star.An exoplanet is discovered by a sudden reduction of light emitted from the star observed, as the planet between the star and the COROT moves.The study of the composition of a star, also known as "astro seismology ', is done by measuring the wavelength of the light of the star. The waves will be from the inside of the star spread and give an indication of the composition of the star.The strength of the COROT lies in the constant observation of the same target in a particular area of ​​space. The observation is immediately after activating the satellite, 60 days ago, began. Another strong point is the accuracy with which the fluctuations in the light emitted by the star is measured.
The first planet discovered by the CoRoT, called CoRoT-Exo-1b has been given, is a very hot gas giant with a diameter of 1.78 times as large as that of Jupiter. It revolves around a dwarf star like our Sun in about 1.5 Earth days. The COROT-Exo-1b is about 1,500 light years distant toward the constellation Unicorn. Using observations from Earth is the mass measured approach, which is approximately 1.3 times that of Jupiter.
