TESS (Transiting Exoplanet Survey Satellite)

TESS (Transiting Exoplanet Survey Satellite) is a NASA space telescope launched in 2018 that scans the sky to find planets outside our solar system. It detects these planets by monitoring the brightness of thousands of stars, looking for tiny, regular dips in light caused by planets passing in front of their stars—called transits. TESS focuses on nearby, bright stars, making it easier for scientists to study the planets' properties. Its mission helps identify promising candidates for further investigation, advancing our understanding of planetary systems and the potential for habitable worlds beyond Earth.
