An article published in the journal “Nature” describes the application of neural networks to gravitational lensing. A team of researchers reduced from a few weeks to a few seconds the time needed to analyze complex space distortions in images captured thanks to gravitational lenses. This could greatly facilitate this type of task with great benefits for astronomical research.

The new “Backyard Worlds: Planet 9” initiative by NASA and various American institutions along with the Zooniverse platform was announced to allow anyone connected to the Internet to participate in the search for the ninth planet of the solar system. You can connect to the project’s website, examine images captured by the WISE space telescope and report any moving objects.
An article published in “The Astrophysical Journal Letters” describes the development and the application of machine learning algorithms to verify the stability of planetary systems. A team of researchers at the University of Toronto Scarborough led by Dan Tamayo experimented this new approach to this type of astronomical research by creating a method a thousand times faster than conventional ones.
An article published in the journal “Journal of Astronomy in Culture” describes a research on the Venus Table contained in the Dresden Codex, one of the few Maya codices still existing today. According to Gerardo Aldana, a professor of anthropology at the University of California – Santa Barbara, it contains significant innovations in mathematics and astronomy, so much to compare its author to Copernicus.
An article published in the journal “Science” describes the discovery of the ancient Babylonian mathematical knowledge. Putting together the translation of various cuneiform tablets, Mathieu Ossendrijver, professor of the History of Ancient Science at Humboldt University in Berlin, concluded that the Babylonians knew the basics of calculus over 14 centuries earlier than previously thought and they used it to calculate the motion of the planet Jupiter.
