Explore the Universe of Exoplanets

Exoplanets are planets that orbit stars beyond our own Sun. Since the first confirmed discovery in 1992, astronomers have identified over 6,107 exoplanets in our galaxy alone, and scientists estimate there could be billions more waiting to be found. These worlds range from scorching gas giants larger than Jupiter to small, rocky planets not unlike Earth.

The search for exoplanets is driven by one of humanity's most profound questions: are we alone in the universe? By studying these distant worlds, their atmospheres, temperatures, and positions within their star's habitable zone, researchers can identify planets where conditions might support liquid water and, potentially, life. So far, 101 exoplanets have been identified as potentially habitable candidates.

Exoplanet Atlas brings together data from NASA's Exoplanet Archive and presents it through interactive 3D visualizations, comparison tools, and educational resources. Whether you're a student, educator, or space enthusiast, you can explore the full catalog, compare worlds side by side, and learn about the methods scientists use to detect planets light-years away.
