NASA, European Astronomers Discovered Earth-Like Planets Around Single Ultra-Cool Dwarf Star

Scientists have been trying to discover habitable environments, places that are conducive to life in the Universe for a long time and now for the first time they have discovered seven Earth-size planets , these are 40 light-years away from Earth in the constellation Aquarius and as these planets are beyond our Solar System they known as exoplanets scientifically. This exoplanet system is called TRAPPIST-1, named on The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) in Chile.

These seven planets circle around an ultra cool dwarf start called Trappist-1, which is barely the size of Jupiter and shine 200 times dimmer than our sun. This Star is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system.

The planets are so near to each other that If an individual was standing on one in all the planet’s surface, they might gaze up and probably see geological structures like mountain, rivers or even clouds of neighboring worlds, which might typically seem larger than the moon in Earth’s sky.

The planets might also be tidally latched to their star, which suggests a.similar side of the planet is usually facing the star, so either side is either perpetual day or night. this indicate that they may have weather patterns which are not like those on Earth.
