NASA Have Made A Brand New Discovery In The Search For Aliens!

Alphabet Inc's Google and NASA said on Thursday that advanced computer analysis identified two new planets around distant stars, including one that is part of the first star system with as many planets as Earth's solar system.

Using machine learning and neural networks to achieve something humans could not, weak signal data from NASA's Kepler space telescope was scrutinized using Google machine learning technology to make the discovery.

The newly discovered eighth planet, called Kepler-90i, was found using machine learning from Google. 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.

Based on four years of input-35,000 possible planetary signals-the pair trained their neural network to detect the pattern of a transiting exoplanet.

Kepler-90i orbits a sun-like star located 2,545 light-years away in the constellation Draco. The exoplanet revolves around its star once every 14.4 days. Called Kepler-90i, the earth-like planet has a surface temperature that exceed 800 °F which are unlikely for any form of life to exist.

The US space agency has discovered a whole solar system with the same number of planets as ours, reports BNT.

The tool also found a sixth planet in the Kepler-80 system, named Kepler-80g.

"The Kepler-90 star system is like a mini version of our solar system".

"You have small planets inside and big planets outside, but everything is scrunched in much closer".

This suggests that there may be hidden worlds and solar systems in the data we have already collected but which we have not noticed because there are so many signals to be tracked.

Like in our solar system, the smaller planets in the Kepler-90 system are found nearer the star, and the bigger planets further away.

While machine learning has been applied before to the Kepler telescope΄s data, it is believed to be the first time that the technology has unearthed a new world.

Automated tests, and sometimes human eyes, are used to verify the most promising signals in the data, but the weakest signals often are missed, it said.

"Kepler has already shown us that most stars have planets", said Paul Hertz, director of NASA's Astrophysics Division in Washington.

"I became interested in applying neural networks to astronomy when I learned that the Kepler mission had collected so much data that it was impossible for scientists to examine it all manually", said Christopher Shallue, a senior software engineer with Google's research team.

Since 2009, Kepler has discovered thousands of exoplanets ranging between Earth-size and Neptune-size (four times the size of Earth).

Shallue, a senior software engineer at Google AI, made a decision to apply a neural network concept to the vast amounts of Kepler data in his spare time.

Regardless, Kepler 90i, third rock though it may be, is too hot to be habitable.

The discovery of this new planet means the Keplar-90 now has eight planets in its solar system, making it the only solar system we know of to have just as many planets as we do. But to say the system is a twin of our own Solar system is a stretch. The result is an extremely stable system, similar to the seven planets in the TRAPPIST-1 system.

Scientists are hopeful that they will find more such planets by applying neural network to Kepler's full set of over 150,000 stars.

NASA astrophysicist Jessie Dotson, the Kepler project scientist, is "so excited to see where this goes next".
