The Quest for Exoplanets
Kepler and TESS Missions
In the pursuit of understanding our place in the cosmos, NASA has turned its gaze beyond our solar system to the myriad exoplanets scattered across the Milky Way. The Kepler Space Telescope, launched in 2009, revolutionized exoplanet science by discovering thousands of planets orbiting distant stars. Building on Kepler's legacy, the Transiting Exoplanet Survey Satellite (TESS), launched in 2018, continues the quest for exoplanets, seeking worlds that may harbor signs of life.
The Search for Habitable Zones
As we explore exoplanets, the concept of the habitable zone becomes pivotal. NASA's Kepler and TESS missions have identified exoplanets residing within the habitable zones of their parent stars—regions where conditions might support liquid water, a crucial ingredient for life as we know it. This tantalizing prospect propels NASA's commitment to uncovering the potential for extraterrestrial life beyond our solar system.
