A new international study, using observations from the Gran Telescopio Canarias at the Roque de los Muchachos Observatory on La Palma, has identified a plasma bubble as the source of the persistent emission observed in some of the so-called fast radio bursts (FRBs), one of the most powerful and unknown cosmic events in the Universe. The data also allow researchers to constrain the nature of the “engine” powering these mysterious sources. The results are published today in Nature. Discovered just over a decade ago, fast radio bursts (FRBs) emit millisecond-long pulses that release an immense

At the present time ground-based observatories have a wide range of instruments which can study the solar surface in the visible and infrared ranges. But it is not possible to combine these observations with those in the near ultraviolet, which cover the wavelength range from 200 to 400 nanometres, nor to maintain them for long periods due to the turbulence in the Earth’s atmosphere. In this context, the Sunrise III mission, in which the Instituto de Astrofísica de Canarias (IAC) is collaborating, “ has become the first observatory to obtain spectropolarimetric data simultaneously in the
