This image shows the gas disc in a computer simulation of a Milky Way-like galaxy from the Auriga suite. Colours represent the ratio of magnesium (Mg) to iron (Fe), revealing that the galactic centre (pink) is poor in Mg, while the outskirts (green) are Mg-rich. These chemical patterns provide important clues about how the galaxy formed.

Fermilab’s neutrino beam accelerator complex in Batavia, Illinois, where scientists created a beam of neutrinos by firing protons into a carbon target, producing charged particles that decay into neutrinos and other particles. The unwanted particles are absorbed by the Earth, leaving a pure neutrino beam that travels to a 14,000-ton detector 500 miles away in northern Minnesota.
