Rare sighting of a luminous jet from a star-eating supermassive black hole

Scientists have observed jets coming from a star being torn apart by a supermassive black hole. The observation has led to two independent publications in Nature and Nature Astronomy.

IceCube finds evidence for neutrinos from a nearby galaxy

Scientists have for the first time found evidence of high-energy neutrino emission from a nearby galaxy, NGC 1068. The results are a new step in the development of so-called multimessenger astrophysics, the study of the universe using many different types of information carriers, from light, to elementary particles, and gravitational waves.
