The new "hunter for exoplanets» NASA will launch on Monday

New NASA telescope designed specifically to search for extrasolar planets, is set to launch on Monday. April 16 Transiting Exoplanet Survey Satellite (TESS), riding on a rocket Falcon 9, to conquer Earth orbit. Learn more about what TESS, we are told here.

TESS said Miss Kepler space telescope, which should be completed by the end of this year. "Kepler" has found more than 5,000 candidates for exoplanets and confirmed about half of them. TESS will be able to explore the 350 times the area of ​​the sky than the "Kepler", and finds about 20 000 exoplanets already in the first two years of operation.

The new

will take about two months after the launch to place a satellite in orbit - halfway from Earth to the Moon - and the experience of his camera. "After that, pour the flow of information," said mission principal investigator George Ricker of the Massachusetts Institute of Technology.

TESS will use the same transit method, which used the "Kepler" to search for planets. A telescope to watch the stars in search of failures in its light - they mean that between the star and planet telescope passes. failure frequency refers to how fast the planet revolves around the star, and the amount of light blocked says the size of the distant body. In contrast to the "Kepler", who has studied the distant stars in a small region of the sky, TESS would study the stars better, but 85% of the heavenly space. The telescope is optimized for monitoring small and cooler stars, emit mostly red light.

"90% of the stars of the Milky Way emit light in red wavelengths, and such stars appear more planets at hand than that of stars like our Sun," said Riker. "Nature seems to say: Look here, look here, and the fact that we are going to deal with."

Because of its proximity to these stars will be ideal targets for the James Webb Space Telescope, which will be launched in 2020. He will search for signs of life in the atmospheres of extrasolar planets.
