The KATRIN (Karlsruhe Tritium Neutrino Experiment) team has published the most accurate measurement to date of the upper limit of the neutrino mass in the journal Science, establishing it at 0.45 electronvolts (eV), less than a millionth of the mass of an electron. The KATRIN experiment, launched in 2018 in Germany, will finalise its neutrino mass measurement campaign this year, having reached 1,000 days of data acquisition.

An international team of researchers has captured the first image of Sagittarius A*, the supermassive black hole at the centre of the Milky Way. The results are published today in a special issue of The Astrophysical Journal Letters.
