First exoplanets discovered thanks to Google’s machine learning engine

Massimo Luciani December 15, 2017 0

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.

The return of three astronauts from the International Space Station marks the end of Expedition 53

A little while ago the astronauts Randy Bresnik and Paolo Nespoli and the cosmonaut Sergey Ryazansky returned to Earth on the Soyuz MS-05 spacecraft, that landed without problems in Kazakhstan. The three of them spent almost 5 months on the International Space Station, where they arrived on July 28, 2017 as part of Expedition 52.

The bright spots on the dwarf planet Ceres suggest a geological activity

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.

New discoveries about the Great Red Spot and radiation areas on Jupiter

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.

Perhaps what looked like liquid water flows on Mars are sand flows instead

Massimo Luciani November 22, 2017 0

An article published in the journal “Nature Geoscience” describes a research in which a team of researchers argues that the signs of liquid water flows found on Mars are actually made up of dry sand. The possible existence of what are technically called RSLs (recurring slope lineae), streaks of sand washed by liquid water, was announced in September 2015 by NASA. A new study of data collected by NASA’s MRO (Mars Reconnaissance Orbiter) space probe may, however, show a different situation.
