The US Space Agency (NASA) announced Thursday the discovery of a new set of planets, a solar system called the Kepler-90 that is composed of eight stars, as well as our, but which are grouped at a distance closer to the star in orbit.
The discovery was made thanks to NASA technology and its Kepler telescope, as well as the artificial intelligence provided by a partnership with the technological giant Google
] Researchers Christopher Shallue and Andrew Vanderburg were responsible for discovered and programmed a computer with artificial intelligence to learn to identify the exoplanets (planets that are located outside our solar system) in the light readings recorded by Kepler, ie a tiny oscillation in the light captured by the telescope as a planet pbaded or pbaded in front of a star.
Inspired and by the way neurons are interconnected in the human brain, this artificial "neural network" identified by Kepler data signals the very weak signals of the pbadage of an eighth planet orbiting Kepler- 90 in the constellation Draco [19659002] About 30% larger than the Earth, Kepler-90i, as it was called this eighth planet, is so close to its star that scientists believe that its average temperature is greater than 425 degrees Celsius, similar to that of Mercury in our
"The Kepler-90 star system called the Kepler-90h star, and it orbits its star at a similar distance to that separating the Earth from the Sun. as a mini version of our solar system.These are small planets inside and large on the outside, but everything is grouped much closer to one. on the other, "says Vanderburg, dear Postdoctoral Fellow at NASA's prestigious Sagan Program and Astronomer at the University of Texas at Austin
Shallue, a software engineer working with Google's Artificial Intelligence Research Team, had the opportunity to work in the field. idea of applying a neural network to Kepler data
Shallue's is interested in exoplanets after discovering that astronomy, as well as other branches of science
"In my free time, I started looking on Google:" find exoplanets with large data sets ", and I discovered the Kepler mission and" The wide range of data available ", has Shallue said.
Paul Hertz, director of NASA's Astrophysics Division, praised the partnership with Google. "
" As we had hoped, there are exciting discoveries in our archived Kepler data that are waiting for the right tool or technology to be unveiled, "said Hertz. This discovery shows that our data will be a treasure available for innovative researchers in the coming years, "added the director of Astrophysics Division of NASA.
