Nasa has found an entire solar system with as many planets as our own, using its planet-hunting telescope Kepler.
The discovery of two new planets around the Kepler-90 star, which is similar to our own Sun, means the solar system has exactly as many planets as our own. That's eight by the way, apparently Pluto doesn't count any more.
The star and its solar system were already known. But the breakthrough came when astronomers found the two new worlds, using Google's artificial intelligence technology.
That suggests that there might be whole worlds and solar systems in data we've already collected, but which we hadn't been able to notice due to the amount of signals to be picked through.
"Just as we expected, there are exciting discoveries lurking in our archived Kepler data, waiting for the right tool or technology to unearth them," said Paul Hertz, director of NASA's Astrophysics Division in Washington. "This finding shows that our data will be a treasure trove available to innovative researchers for years to come."
