Today, the German eROSITA consortium released the data for its share of the first all-sky survey by the soft X-ray imaging telescope eROSITA flying aboard the Spectrum-RG (SRG) satellite. With about 900,000 distinct sources, the first eROSITA All-Sky Survey (eRASS1) catalogue has yielded the largest X-ray catalogue ever published.

The Low Frequency Array (LOFAR) world’s largest and most sensitive radio telescope operating at low radio frequencies. LOFAR was previously organised as a project and is now, on 22nd January, being transformed, into an independent legal form: a consortium for a European research infrastructure.

New observations and sophisticated methods provide new and unexpected insights into the magnetic secrets of a star: the magnetic braking of a star's rotation is weakened with increasing age. This influences the habitability of exoplanets.
