NASA's planet hunter satellite

How exactly satellites scan space ..NASA's planet hunter satellite is known as the Transiting Exoplanet Survey Satellite (TESS).TESS was launched on April 18, 2018, to discover and characterize exoplanets around nearby stars. It uses the transit method to detect exoplanets, which involves monitoring the brightness of stars for periodic dips caused by planets passing in front of them.TESS scans large portions of the sky, divided into 26 sectors, and observes each sector for about 27 days to search for exoplanets. The satellite is equipped with four wide-angle cameras that can monitor nearly the entire sky, searching for changes in brightness of over 200,000 stars.TESS has been highly successful in its mission, discovering numerous exoplanets, including some that are potentially habitable. It has identified a wide range of exoplanet types, from small rocky worlds to large gas giants.TESS data is publicly available, allowing scientists and astronomers from around the world to study and analyze the findings. The satellite has significantly contributed to our understanding of exoplanets and their distribution in the galaxy.TESS has laid the groundwork for future missions, such as the James Webb Space Telescope, to further explore and characterize exoplanets.
