TRAPPIST-1 looks small and calm from Earth. Up close, it is anything but. The cool red star about 40 light-years away erupts with bursts of energy many times each day, sending radiation racing across ...

"This artist's concept shows what the TRAPPIST-1 planetary system may look like, based on available data about the planets' diameters, masses and distances from the host star, as of February 2018." ...

Located about 39 light-years from Earth, the TRAPPIST system resembles a miniature version of our solar system: The star, an ultracool red dwarf, and all its planets would comfortably fit inside the ...
