NASA announced a Seven new system of Exoplanets, which are Earth-size, and could potentially hold life.These exoplanets are located outside of our solar system and orbit a star. NASA has named the system of planets after the ‘Transiting Planets and Planetesimals Small Telescope,’ which is located in Chile. This telescope first discovered three of the planets in this system in May 2016. Unlike Earth, which rotates on its axis, the planets are “tidally locked to the star.” This means that one side of the planet has only day, and one side has only night. It also means the weather conditions are unlike what we experience on Earth.
