A study led by Anelise Audibert, a researcher at the Instituto de Astrofísica de Canarias (IAC), reveals a process that explains the peculiar morphology of the central region of the Teacup galaxy, a massive quasar located 1.3 billion light-years away from us. This object is characterized by the presence of expanding gas bubbles produced by winds emanating from its central supermassive black hole. The study confirms that a compact jet, only visible at radio waves, is altering the shape and increasing the temperature of the surrounding gas, blowing bubbles that expand laterally. These findings

Scientists have discovered a new ring system around a dwarf planet on the edge of the Solar System. The ring system orbits much further out than is typical for other ring systems, calling into question current theories of how ring systems are formed. The discovery, published in Nature, was made possible thanks to the HiPERCAM instrument on the Gran Telescopio Canarias (GTC) at the Roque de los Muchachos Observatory in La Palma. A system of rings has been discovered around the dwarf planet Quaoar which is approximately half the size of Pluto and orbits the Sun beyond Neptune. The discovery
