With every passing year, more and more extra-solar planets are discovered. To make matters more interesting, improvements in methodology and technology are allowing for the discovery of more planets within individual systems. Consider the recent announcement of a seven-planet system around the red dwarf star known as TRAPPIST-1.
At the time, this discovery established the record for most exoplanets orbiting a single star. Well move over TRAPPIST-1!
Thanks to the Kepler Space Telescope and machine learning, a team from Google AI and the Harvard-Smithsonian Center of Astrophysics (CfA) recently discovered an eighth planet in the distant star system of Kepler-90. Known as Kepler -90i, the discovery of this planet was made possible thanks to Google algorithms that detected evidence of a weak transit signal in the Kepler mission data.
The study which describes their findings, titled “Identifying Exoplanets with Deep Learning: A Five PLanet Resonant Chain Around Kepler-80 and an Eight Planet Around Kepler-90“, recently appeared online and has been accepted for publication in The Astronomical Journal. The research team consisted of Christopher Shallue of Google AI and Andrew Vanderburg of the University of Texas and the CfA. Read more from universetoday.com…
