On 14 December, NASA has discovered two new exoplanets seeking little help from Google. The researchers used artificial intelligence for exoplanet discovery to analyze the data from Kepler-a telescope placed in space.
Exoplanet Discovery in Space:
Kepler-80g was discovered in the planetary system around Kepler-80. Kepler 80 assigned as a star which forms the distance of about 1364 light years. However, this planet already has five exoplanets – 80b, 80c, 80d, 80e, and 80f around it. 80g now named as an outermost planet in the system.
Indeed, the new planet named as Kepler-90i. It was found while orbiting Kepler 90. Kepler-90 star forms a distance of about 2722 light years. Previously, it had seven planets around it – Kepler-90b, 90c, 90d, 90e, 90f, 90g, 90h. 90i discovered in between c & d.
Why Kepler-90i Becoming Interesting Discussion?
The new discovery of Kepler-90i has matched Kepler-90 of our solar system. It now became the first star to have many planets as our solar system has.
Any Features Resembling our Solar System?
According to NASA website, Kepler-90 have a similar configuration to our solar system. Larger planets found a quite distance from the planet while smaller planets found orbiting close to the planet. The exoplanet discovery has shown that the outer planets formed in the cooler zone of the solar system.
Hand of Artificial Intelligence in Exoplanet Discovery:
“From the millions of data received from Kepler, the programmers trained the computer to pick up specific clues regarding orbit calculation, sense change in brightness when a planet passes across etc., and apply certain algorithms for detection of exoplanets. When all the clues matched the machine was able to interpret and give a positive result. Using machine learning techniques, we can detect even weaker signals that can be missed when done manually,” explains Prof. Sengupta Sujan K., Professor at Indian Institute of Astrophysics, Bengaluru.
