Artificial intelligence finds solar system with eight planets like ours

The planet, Kepler 90i, is scorching hot (about 800 degrees Farenheit) and rocky, located in the Kepler-90 system about 2,500 light-years away from Earth, Vanderburg said Thursday during a NASA teleconference.

"There are simply too many weak signals to examine using the existing methods", Shallue said. In October 2016, Shallue, who is interested in astronomy, chose to use about a fifth of his time at work (Google calls it 20% time, and allows its employees to pursue a pet project during those hours) to find a way to use machine learning to more quickly cipher through Kepler's data. "You have small planets inside and big planets outside, but everything is scrunched in much closer", said Vanderburg. The neural system figured out how to recognize these by utilizing signals that had been considered and affirmed in Kepler's planet list. Ninety-six percent of the time, it was accurate.

Astronomers had never before observed an eight-planet network beside the solar system that includes Earth, researchers said.

The researchers used the neural network to parse Kepler image data taken from 670 stars, and the neural network then indicated that two "weak signals" were likely to be planets. NASA unveiled the discovery of the eighth known planet in the system, Kepler-90i, on December 14, 2017.

Shallue likened this process to "looking for a needle in a haystack".

"Kepler-90i is not a place I'd like to go visit, though", said Vanderburg. It's not a neighborly situation. In our nearby planetary group, the nearest planet to the sun, Mercury, has a circle of 88 days.

One other way that the Kelper-90 system resembles our own, is that the planets there orbit their sun from a mostly small-large, as reported by The Daily Mail.

Still, Tillerson had planned to reiterate his call at a special United Nations ministerial meeting on North Korea at the council Friday morning.

"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, Astrophysics Division director at NASA, in a press release. "This discovering demonstrates that our information will be a fortune trove accessible to imaginative scientists for a considerable length of time to come". It additionally has a circle of 14.4 days. Five of the six planets frame a resounding chain, in which they are secured circle by common gravity. This pattern is evidence that the system's outer gas planets-which are about the size of Saturn and Jupiter-formed in a way similar to our own.

Since the telescope's launch, about 2,500 exoplanets have been confirmed, according to NASA.

Scientists found it by using machine learning from Google.

While machine learning has been used before in the search for planets beyond our solar system, it is believed to be the first time an artificial neural network like this has been used to find a new world.

When scientists hunt for an exoplanet, they look for dips in the brightness of far-away points in space that otherwise look like stars.

Leave it to Google to make Kepler even better. It has enough fuel to continue distinguishing hopefuls until summer 2018.
