Nasa scientists have discovered 715 new planets. This means that there are a total of 1700 planets beyond the solar system.
Four of this 715 new planets were about 2 and a half times as big as the Earth and were discovered with a space telescope called Kepler.
This discovery was achieved thanks to a new techique and means that astronomers almost doubled the total number of planets known to humanity.
Opinion: I really admire the scientists' work. It is very amazing to know that we are sorrounded by 1700 exoplanets. Kepler telescope is a great tool also because is being improved and we may know in the future more details about these planets.
