366 exoplanets discovered thanks to AI

ExoMiner is an AI implemented by NASA teams, capable of spotting exoplanets in our galaxy. His first search in the Kuiper Space Telescope archives was astounding.

We know today that there are many planets outside our solar system, we speak of exoplanets, in the same way that any form of life coming from outside the Earth would be called extraterrestrial. The Kepler space telescope has made itself during its 10 years of service, an expert on this question of exoplanets.

He spotted thousands of them and if his mission ended in 2018, for lack of sufficient fuel, many astronomers around the world are still looking in the surveys for traces of additional exoplanets.

With the use of a new deep neural network, scientists have succeeded in revealing the existence of more than 350 exoplanets in our galaxy. Thanks to this new research model, called ExoMiner, scientists ensure that they are now able to sort between real exoplanets and “False positives” still quite numerous in the results.

An AI with stunning results?

Very confident about the capabilities of their AI, scientists assure that “when ExoMiner says something is a planet, you can be sure it’s a planet ”. A statement that we owe to the head of this project Hamed Valizadegan. The latter does not hesitate to make the comparison between man and machine, ensuring that his artificial neural network is “in some cases more precise than human experts ”.

With regard to the 366 planets discovered, if their number can impress this harvest of size did not finally make it possible to find planets similar to the Earth. None are in fact in the habitable zone of its orbit. An announcement that is not surprising, this area of ​​the systems is the first that scientists observe and they give it special attention. It would have been more than astonishing if they had passed by a planet in these orbits.

But ExoMiner is far from having said its last word and the AI ​​intends to develop its knowledge about planets in order to attack data from other telescopes such as TESS or even PLATO, a European space telescope whose launch is scheduled for 2026.
