The TRAPPIST-1 system, located about 41 light years from Earth, has been a focal point of much exoplanetary discussion - mainly because it has 7 confirmed planets orbiting a dim M-dwarf star. Two of those planets - TRAPPIST-1e and -1f - are thought to be in the stars habitable zone. However, the habitable zone of M-dwarfs is so close to the star itself the planets are likely tidally locked to it, meaning they have a permanent day and night side, with a twilight terminator in between. Armed with that knowledge, scientists have been attempting to model the climate on these two exoplanets, and a new paper from Jacob Haqq-Misra of Blue Marble Space uses a new type of climate model to accurately do so with much less computational power.
