What's next for NASA's TESS exoplanet hunter?

April 23, 2018

The satellite may be small, but it packs a major science punch. TESS is following in the footsteps of NASA's famed Kepler space telescope and is expected to surpass its predecessor in the number of exoplanets detected.  Over the course of its two-year mission, TESS will monitor the brightness of more than 200,000 stars, waiting to observe tiny dips in starlight known as transits.
