[TEXT: TESS’s first year of science] In September, the TESS team released its first sector image, a large strip of sky monitored for 27 days. [TEXT: First science image] By the end of 2018, astronomers announced the missions first new exoplanets. [TEXT: First planets] A few months later, astronomers announced the discovery of TESS’s first Earth-size exoplanet.

[TEXT: Beta Pictoris comets] TESS’s cameras even catch many supernovae, bright explosions that mark the deaths of stars, from their very start.
