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.

New study sheds light on the Milky Way’s mysterious chemical history

The Hubble constant describes the rate at which the universe is expanding. However, current measurements do not agree on its value, which has generated an intense scientific debate known as the “Hubble tension.”

An international team led by the UB will study the validity of the current cosmological model

Artist’s impression of a globular cluster near its birth, hosting extremely massive stars with powerful stellar winds that enrich the cluster with elements processed at extremely high temperatures (left), and an ancient globular cluster as we observe them today, where surviving low-mass stars retain traces of the winds from those extremely massive stars, which have since collapsed into intermediate-mass black holes (right).

An artist's impression of Japan’s Hayabusa2 space mission touching down on the surface of the asteroid 1998 KY26. New observations with ESO’s Very Large Telescope (VLT) have revealed that 1998 KY26 is just 11 m wide, almost three times smaller than previously thought, and is spinning once every 5 minutes, which is much faster than expected. The image above shows an updated size comparison between the asteroid and spacecraft.
