1.0 IntroductionFor centuries, humanity has speculated about the existence of planets outside our own solar system (NASA Website). These planets, called exoplanets, orbit a star other than the Sun (Ridpath, 2012). In the 20th century, Edwin Hubble observed “islands” surrounded by stars far beyond our solar system (NASA website). This observation proved that there is potential for habitable planets other than Earth (NASA website). Two dates are mentioned for the discovery of the first exoplanet. Some say the first exoplanet discovered was in 1992 (Super Wasp website). Others say it was discovered in 1995 by Michel Mayor and Didier Queloz (NASA website). They used the radial velocity method which determined the planet's mass to be about half that of Jupiter and were observed orbiting near the star 51 Pegasi (NASA website). . The most recent confirmed exoplanet count to date is 1,692 (NASA website). This report will provide information about exoplanets, how they are discovered and studied, and past and future research projects.2.0 Exoplanet Search2.1 Habitable ZoneScientists believe that the most possible place for life is on a small rocky "Earth-like" planet in a habitable zone (Super Wasp website). A habitable zone (Fig. 1) is where temperatures are suitable for the presence of liquid water on a planet's surface (NASA website). A star's habitability depends on the amount of light it absorbs and reflects, which determines its temperature (Astrobio website). 2.2 Super-Earths A super-Earth is a planet whose mass is between one and ten times that of Earth (Phys Org website). They have an incidence of 41% in habitable zones (Phys Org Website).2.3 Missions/OrganizationsDue to the difficulties of detecting an exoplanet due to...... middle of paper ...... zone , methane and water (Website Space of the Telescope Scientific Institute). It will be able to reveal the causes of star formation and the interactions between dark matter and galaxies (Space Telescope Science Institute website). Additionally, the angular resolution will be 5 to 10 times better than that of the James Webb Space Telescope (Space Telescope Science Institute website).5.0 ConclusionsThe hunt for exoplanets in the habitable zone will continue until they can meet the question of whether life can exist outside of our planet. galaxy. Exoplanets have been discovered through launched missions such as Kepler, SETI and TESS. These planets are studied using cutting-edge technology, including spectroscopic analyzes and transit spectroscopy. The proposed satellites will be launched in the future and will collect more detailed information that will bring us closer to the answer..
