A telescope for the search for the exoplanet TESS, which is positioning itself as a partial replacement for the Kepler telescope, began its work
The NASA Transoceanic Exoplanet Observation Satellite
developed jointly by MIT and NASA. His task, like Kepler, is to search for planets through a transit method, that is to say, to follow the change in brightness of a star during the passage of the planet on his disk. that the big difference between the new mission is that scientists will explore the object Kepler studied the stars within three thousand light years
According to the agency, TESS is equipped with four telescopes with a matrix 16.8-megapixel expansion operating in the spectral range of 600. up to 1000 nanometers. Each of these telescopes has a view of 24 degrees and they are directed to form a single elongated band-shaped field of view
Once in 27 days, the telescope changes viewing area and for two years the main mission creates a map. which covers 85% of the totality of the celestial sphere.
