Nasa finds solar system filled with as many planets as our own

Nasa has found an entire solar system with as many planets as our own. The discovery of a new planet around the Kepler-90 star, which looks like our own sun, means the distant solar system has a total of eight known planets. And those planets look like those in our own neighbourhood: rocky planets orbit close to the star, with gas giants further away. The star and its family of planets were already known about, having been detected by the Kepler space telescope. But the breakthrough came when astronomers found the new world, which was done using Google's artificial intelligence technology.
