In less than 25 years, the study of exoplanets has grown from a niche field to one with groups at most universities, international conferences, and prominent NASA and European missions. Exoplanet discoveries have moved from individual finds to announcements of hundreds of planets at a time. Currently, there are more than 4,200 confirmed exoplanets with the majority of these discovered by measuring the dimming as they pass in front of their host star. The discovery of thousands of exoplanets by NASA's Kepler Mission has shown that planets orbit most stars in our Galaxy and that potentially habitable planets are common. Scientists are working now to understand the characteristics of these planets, including their sizes, masses, and composition. The TESS Mission has so far found more than 50 nearby planets that can be targets for current and future telescopes to detect and characterize their atmospheres and look for indications of life.&nbsp;
