\n More than 4,000 exoplanets have been discovered so far by astronomers. Now, artificial intelligence has discovered an additional 50, thanks to old data from NASA.<\/p>\n

Researchers built the algorithm to comb through old data from NASA\u2019s Kepler Space Telescope, which was retired in October 2018. The AI was trained to look for signs of real exoplanets and false positives at a faster rate than previous methods. It can also be automated and improved without the researchers training it further.<\/p>\n

\u201cThe algorithm we have developed lets us take fifty candidates across the threshold for planet validation, upgrading them to real planets,\u201d the study\u2019s lead author, University of Warwick professor David Armstrong, said in a statement. \u201cWe hope to app<\/a>ly this technique to large samples of candidates from current and future missions like TESS and PLATO.\u201d<\/p>\n

\u201cIn terms of planet validation, no-one has used a machine learning technique before,\u201d Armstrong added. \u201cMachine learning has been used for ranking planetary candidates but never in a probabilistic framework, which is what you need to truly validate a planet. Rather than saying which candidates are more likely to be planets, we can now say what the precise statistical likelihood is. Where there is less than a 1% chance of a candidate being a false positive, it is considered a validated planet.\u201d<\/p>\n

This isn\u2019t the first time researchers have trained an algorithm to find data NASA researchers missed. In February, researchers from the Netherlands discovered 11 \u201cpotentially hazardous objects\u201d using advanced artificial intelligence.<\/p>\n

The 50 exoplanets vary in size and scope. Some of them are as large as Neptune, while others are smaller than Earth. Orbits also vary in length, with some approaching 200 days in length, while others orbit their star in just one day.<\/p>\n

With the AI having been trained and deemed faster than other techniques, the researchers hope that planetary scientists will use multiple methods to search for exoplanets.<\/p>\n

\u201cAlmost 30% of the known planets to date have been validated using just one method, and that\u2019s not ideal,\u201d Armstrong added. \u201cDeveloping new methods for validation is desirable for that reason alone. But machine learning also lets us do it very quickly and prioritize candidates much faster. We still have to spend time training the algorithm, but once that is done it becomes much easier to apply it to future candidates. You can also incorporate new discoveries to progressively improve it.\u201d<\/p>\n

Armstrong hopes the algorithm could be used to analyze NASA\u2019s Transiting Exoplanet Survey Satellite (TESS).<\/p>\n

\u201cA survey like TESS is predicted to have tens of thousands of planetary candidates and it is ideal to be able to analyze them all consistently,\u201d the researcher said. Fast, automated systems like this that can take us all the way to validated planets in fewer steps let us do that efficiently.\u201d<\/p>\n

The study was published in the Monthly Notices of the Royal Astronomical Society.<\/p>\n

Since its launch in April 2018, NASA\u2019s Transiting Exoplanet Survey Satellite (TESS) has found a great number of exoplanets, including a so-called \u201cmissing link\u201d and one it \u201crediscovered.\u201d<\/p>\n

In January 2020, TESS discovered its first Earth-sized planet in a star\u2019s \u201chabitable zone,\u201d an area that could allow for liquid water to be on the surface.<\/p>\n

More than 4,000 exoplanets have been discovered by NASA in total, approximately 50 of which were believed to potentially be habitable as of September 2018. They have the right size and the right orbit of their star to support surface water and, at least theoretically, to support life.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
