Eight Exoplanets Orbit Sun-Like Star Kepler-90

Scientists announced on Thursday they have found, for the first time, an eighth planet in a distant star system, tying it with our own solar system for having the most known planets.

The software's artificial "neural network" combed through data about 670 stars, which led to the discovery of planets Kepler 80g and Kepler 90i.

Two new exoplanets have been discovered thanks to NASA's collaboration with Google's artificial intelligence (AI). In order to help find weaker signals of potential planets that researchers had missed, the neural network was trained to look for weak signals in star systems that were known to support multiple planets.

"This finding shows that our data will be a treasure trove available to innovative researchers for years to come", said Paul Hertz, director of NASA's Astrophysics Division, in the release.

According to AP, Shallue also said Google planned to make public the code needed to do searches for planets outside of our solar system using a home computer and the publically available Kepler data.

The entire Kepler-90 system of eight planets would easily fit within Earth's orbit of the Sun.

NASA estimated the planet΄s surface temperature to be around 426 degrees Celsius (800 Fahrenheit) and said it likely was inhospitable to life.

"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-80g is an Earth-sized planet that is gravitationally locked in a resonant chain with four of its fellow planets, forcing them to orbit their star nearly as if they were all moving to the music of a highly choreographed dance. "You have small planets inside and big planets outside, but everything is scrunched in much closer", said Vanderburg. And while it was the eighth planet discovered in the system, it is actually third in line from the sun-just like Earth.

With the discovery of Kepler-90i, the solar system is now tied with the Kepler-90 star system with the most number of planets.

Scientists found it by using machine learning from Google.

How did NASA find the planet?

The new planet has been dubbed Kepler-90i. They essentially trained a computer to identify exoplanets based on Kepler's observations in changing stellar brightness - the subtle, fleeting dip in a star's brightness when a planet passes in front of it. A sixth exoplanet in the Kepler-80 system was also found by the same process.

Researchers had known that seven planets were orbiting the star. "If you have a finer sieve then you will catch more rocks but you might catch more jewels, as well". The research paper reporting this finding has been accepted for publication in The Astronomical Journal.

The next three planets beyond Kepler-90i - 90d, 90e and 90f - fall into a sub-Neptune size class and complete an orbit every 60, 92 and 125 days, respectively.

"These results demonstrate the enduring value of Kepler's mission", said Jessie Dotson, Kepler's project scientist at NASA's Ames Research Center in California.

Shallue, a senior software engineer with the Google AI team, came up with the idea of applying a neural network to Kepler data. "I hope it may give people more of a reason to go into astronomy to use more advanced technology like this".
