taken on July 25 by the Transiting Exoplanet Survey Satellite. The angular extent of the widest field of view is six degrees. Visible in the images are the comet C/2018 N1, asteroids, variable stars, asteroids and reflected light from Mars. TESS is expected to find thousands of planets around other nearby stars.

The Pacific Ocean teems with phytoplankton along the West Coast of the United States, as captured by the MODIS instrument on NASA’s Aqua satellite. Satellites can track phytoplankton blooms, which occur when these plant-like organisms receive optimal amounts of sunlight and nutrients. Phytoplankton play an important role in removing atmospheric carbon dioxide. Credits: NASA
