EXOPLANET/ASTROBIOLOGY IMPORTANT DATES

My research into exoplanets and Astrobiology led me to develop this page on the website. It is a chronological listing of important dates in the field of exoplanet and Astrobiology research and discoveries. Currently it is not an exhaustive list. Over time it will be updated.

1992: First exoplanets discovered orbiting a pulsar (PSR B1257+12). These planets are not habitable due to the extreme radiation environment.
1995: First exoplanet discovered orbiting a sun-like star (51 Pegasi b). This discovery revolutionized our understanding of planetary systems.
1999: First transiting exoplanet observed (HD 209458 b). The transit method allows for the study of exoplanet atmospheres.
2001: First detection of an exoplanet atmosphere (HD 209458 b). This marked the beginning of exoplanet characterization.
2005: First direct image of an exoplanet (2M1207 b). This was a major milestone in exoplanet observation.
2009: Kepler Space Telescope launched. Kepler's mission was to discover exoplanets, especially those in the habitable zone.
2010: First potentially habitable exoplanet discovered (Gliese 581 g). The existence of this planet is still debated.
2015: TRAPPIST-1 system discovered. This system has seven Earth-sized exoplanets, some of which are in the habitable zone.
2018: TESS launched. TESS is conducting an all-sky survey for exoplanets using the transit method.
2021: James Webb Space Telescope launched. JWST will play a crucial role in characterizing exoplanet atmospheres and searching for biosignatures.
2025: As of now, thousands of exoplanets have been discovered, and the search for life beyond Earth is ongoing. Future missions will continue to push the boundaries of exoplanet exploration and astrobiology.
