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.

Massive stars in the Small Magellanic Cloud. Of the stars studied, seventy percent (the red diamonds) appear to accelerate and decelerate. This indicates the presence of a partner. (c) ESO/Sana et al.

Massive stars in metal-poor environment often have close partners
