NASA's James Webb Telescope to Receive Cute Companion for Alien Exploration.

NASA has selected a toaster-sized cubesat called MANTIS to accompany the James Webb Space Telescope on its mission to study exoplanets. MANTIS will observe stars in the full range of ultraviolet light, including extreme UV light, which will help the cubesat study stars that burn dozens of light-years away from Earth. MANTIS will fill in the blanks for the much larger telescope, providing context on the stellar environments in which these planets live. The observations could provide a glimpse of worlds that could harbor life.
