Artificial intelligence finds solar system with 8 planets like ours

As for Kepler-90, its planetary system could have more than eight planets, the scientists pointed out - they could just lie farther away from the star and not have orbited enough times for Kepler to have spotted them during its primary mission.

The planet was discovered in data from NASA's Kepler Space Telescope.

The star and her family of planets were already known after being discovered by the Kepler Space Telescope. Inspired by the way neurons connect in the human brain, this artificial "neural network" sifted through Kepler data and found weak transit signals from a previously-missed eighth planet orbiting Kepler-90, in the constellation Draco. Consequently, Kepler-90i has an average surface temperature of 800 degrees Fahrenheit, and is not a likely place for life as we know it.

"The Kepler-90 system is like a mini version of our Solar System", said Dr. Andrew Vanderburg, an astronomer at the University of Texas at Austin. Kepler-90h, the outermost planet in the system, orbits its star at a similar distance as Earth does to the Sun.

For the first time, another solar system has been found in our galaxy with eight planets, just like our own - and it was Google's artificial intelligence that found it. "You have small planets inside and big planets outside, but everything is scrunched in much closer".

This is the first time that experts find another star system with the same number of planets.

After this discovery, the Kepler-90 solar system has come at par with our own in terms of number of planets revolving around a single star, said NASA.

Advancements in hardware and new techniques for machine learning have made it possible in recent years for automated software to tackle data analysis in science, finance and other industries.

Kepler has produced an unprecedented data set for exoplanet hunting.

"There are simply too many weak signals to examine using the existing methods", Shallue said.

NASA and Google also held a Reddit Ask Me Anything session on Thursday to answer public questions. As in ours, Kepler's small, rocky planets are closest to the sun and its gas giants farthest away. It has a shorter orbit than Mercury's, completing a circle around its star once every two weeks. Kepler has gathered four years of data on what's in the sky and found 150,000 stars - much more than people could see.

"We've come a long way in our understanding of planetary systems", said Jessie Dotson, Kepler's project scientist at NASA's Ames Research Center in Northern California, which manages the Kepler and K2 missions. He also compared the finding of exoplanets to sifting through rocks with a fine sieve to find jewels.

The TRAPPIST-1 star, an ultra-cool dwarf, has seven Earth-size planets orbiting it.

Besides, he said that this information would be a "treasure trove" that other experts will be able to use fpr further research. In the statement, the agency says that with the help of advanced computer analysis they have identified two new planets around distant stars.

After the neural network was trained manually to identify passing exoplanets by analyzing 15,000 signals from the Kepler catalogue, it started giving correct results for true planets and false positives in 96 percent of cases.
