At a press conference, the annoucement came of the first exoplanets discovered thanks to the TensorFlow machine learning engine created by Google. Researchers Christopher Shallue and Andrew Vanderburg trained this system to make it recognize exoplanets in the data collected by NASA’s Kepler space telescope. The two exoplanets announced are Kepler-90i and Kepler-80g but it’s only the beginning for a new way to look for exoplanets, especially the smaller ones that leave very weak traces.

At the annual American Geophysical Union meeting, NASA scientists presented the results of the latest research on bright spots on the dwarf planet Ceres. In particular, the activity detected over time, especially by NASA’s Dawn space probe with variations in their brightness confirm the possibility that on Ceres there’s still a geological activity that is modifying this dwarf planet’s surface.

Yesterday at the annual American Geophysical Union meeting the new discoveries concerning Jupiter’s Great Red Spot of Jupiter and a new ​​radiation area were announced. The data collected by NASA’s space probe Juno during a flyby on July 11, 2017 allowed to discover something new about that storm bigger than Earth, for example finding an answer to one of the crucial questions about it establishing that it’s about 300 kilometers (200 miles) deep.

An article published in the journal “Science” describes a precise measurement of the magnetic field of the corona of the black hole V404 Cygni. A team of researchers used the data collected in 2015 during a violent outburst of energy connected to the emission of jets from the black hole detected at many wavelengths using various space and ground-based telescopes. The result of this measurement was very surprising, being about 400 times lower than previous estimates.
