Through the use of an Artificial Intelligence from the Google search engine, the National Aeronautics and Space Administration (NASA) managed to identify an eighth planet orbiting Kepler-90, a sun-like star located 2,545 light-years from Earth. The discovery shows that “there is another star system similar to our solar system with the same number of planets orbiting a single star,” the space agency said in a statement. However, the Kepler telescope had already picked up the signal, from this newly discovered and extremely hot planet, which they have dubbed Kepler-90i, but it was so weak that it had gone unnoticed by astrophysicists.
“The Kepler-90 star system is a miniature version of our solar system with small planets inside and large planets on the outside, but these are much tighter,” explains Andrew Vanderburg, an astronomer at the University of Texas at Austin. . According to The Verge, the Kepler Space Telescope has been searching the galactic sky for exoplanets, or planets outside our own Solar System, since it was launched in 2009. To examine all the information that has been captured since that launch, scientists they usually look at the strongest signals first. About 30% larger than Earth, it is so close to its star – it gives a full turn in 14.4 days – that the average temperature on its surface exceeds 426 degrees Celsius, as in the case of Mercury.
