Exploring Alien Worlds: NASA's Search for Exoplanets

Embark on a journey with NASA as it ventures beyond our solar system in search of exoplanets, distant worlds orbiting stars far beyond our sun.


NASA's Kepler Space Telescope revolutionized exoplanet science, discovering thousands of exoplanets by detecting the subtle dips in starlight as planets pass in front of their host.

Kepler Space

The Transiting Exoplanet Survey Satellite (TESS) continues Kepler's legacy, scanning the sky for transiting exoplanets closer to Earth, offering prime targets for follow-up studies.

TESS Mission

NASA employs a range of techniques, including spectroscopy, to characterize exoplanets, providing insights into their atmospheres, compositions, and potential habitability.


Scientists focus on exoplanets located within the habitable zone of their host stars, where conditions may be just right for liquid water to exist, a key ingredient for life as we know it.

Habitable Zone

NASA's discoveries include rocky, terrestrial exoplanets similar to Earth, as well as gas giants like Jupiter, offering a diverse range of planetary systems to study.

Gas Giants

Studying the atmospheres of exoplanets provides valuable clues about their potential habitability and the presence of key molecules such as oxygen, methane, and water vapor.


NASA plans future missions, such as the James Webb Space Telescope (JWST), to further explore exoplanets and their atmospheres, pushing the boundaries of our understanding.

Beyond Kepler

With each new discovery, NASA brings us closer to answering the age-old question: Are we alone in the universe.
