The Transiting Exoplanet Survey Satellite, or TESS, is currently looking all over the sky at 200,000 nearby stars, searching for new planets. It does this by measuring how a star’s brightness changes over time. A planet that travels in front of its star will block out the star’s light, which TESS will measure as a dimming. This method can also tell us about the planet’s size, orbit, and even a bit about its atmosphere.
