The Subaru Telescope in Hawaii recently used the Hyper Suprime-Cam to carry out a deep sky survey from the University of Tokyo. It reported a Sigma Eight (S8) value of 0.747, which matches earlier results from gravitational lensing studies. Sigma Eight (S8) is a key measure in cosmology that shows how matter is clustered or “clumpy” across the universe on a scale of 26 million light-years. It tells scientists how much visible and dark matter is gathered in different parts of space. This finding helps us understand how the universe evolved from a smooth early state after the Big Bang.

IXPE is a joint satellite mission by the National Aeronautics and Space Administration (NASA) and the Italian Space Agency, launched on December 9, 2021. It is the first satellite designed to measure the polarisation of X-ray light, helping scientists study extreme cosmic environments. The mission focused on blazars, which are a type of active galactic nucleus with a supermassive black hole ejecting a powerful jet of particles aimed toward Earth.
