A team of scientists reviewing information from the Kepler Space Telescope came across evidence of the existence of 20 previously unknown exoplanets.
For analysis, the device used is Robovetter - sifting Kepler's information to find potential inhabited alien worlds. It turned out that many of the 20 candidates have long orbits (for KOI-7923.01 - 395 days) and are close to earth size. They are also cooler than our planet because of the distance from the star and its low heat. But to sustain life is enough. Unfortunately, these planets have not yet been confirmed, because the telescope was faced with the problem of recording the considered celestial territory. As a result, he followed them twice, and this is not enough to write to the official catalog. But the team is confident that they have found not only planets, but also possible habitats.
The detection is derived from photometry information from a 4-year telescope review. Earth observations will be required to validate the data.
