The Search for Another Earth
What is an Exoplanet?
An exoplanet is any planet beyond our solar system. Most orbit other stars, but free-floating exoplanets, called rogue planets, orbit the galactic center and are untethered to any star. The first confirmation of detection of exoplanets occurred in 1992.
The Habitable Zone
Also known as the "Goldilocks Zone", this is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure. NASA's Kepler and TESS missions have discovered thousands of these worlds, some of which may harbor life.
