NASA’s array of technological marvels includes the Kepler Space Telescope, now retired, and its successor, TESS, the Transiting Exoplanet Survey Satellite, still operating on an extended mission. Both were built to hunt for those shadows – a tiny dip in starlight as an “exoplanet,” a planet beyond our solar system, crosses the face of its parent star. Finding exoplanet shadows is called the “transit” method.

There's a helpful concept we use for the distance from a star where you might find planets with liquid water on their surfaces – water being essential for life as we know it. It's called the habitable zone. Every star has one, but they're not all equal.
