    1. The UV radiation rates emanating from the host star in the TRAPPIST-1 system are large enough to have caused the planets to have hemorrhaged large amounts of water over time. The inner planets of the system, TRAPPIST-1b and -TRAPPIST-1c, could have lost more than 20 times the amount of water contained in Earth’s oceans over the course of 8 billion years.

      Following the developments on the planets in the TRAPPIST system are so interesting. It's hard to believe that the examination of exoplanets is so recent!
