TESS (Transiting Exoplanet Survey Satellite)

This illustration of NASA's TESS shows the spacecraft in shades of blue. The multi-sided, cylindrical shaped main body of the satellite has two solar array "wings," each extending out from the sides of the satellite which is attached to an open, cone shaped bottom piece. Nestled inside the cone are four squares which show the relative positions of TESS’s cameras.

TESS was designed to detect exoplanets, worlds beyond our solar system. In the course of its extended observations of the sky, it also discovers all types of objects that change in brightness, from nearby asteroids to pulsating stars and distant galaxies containing supernovae.
