A researcher from Comillas participates in the findings published by Nature Astronomy on the functioning of Jupiter's auroras
According to the journal Nature Astronomy, Jupiter not only has aurorae borealis, but also has austral auroras, and both operate independently. Raquel Caro-Carretero, a Professor at the ICAI School of Engineering, has been very active in this finding, which questions the current theories on how auroras are generated on Jupiter,
Auroras are planetary phenomena that take place when the wind from particles of energy from a star collides with the magnetic field of a planet (magnetosphere). "In the case of Jupiter, which has a powerful magnetic field, it acts like a gigantic magnet that houses intense auroras, but until now these phenomena had only been observed with X-rays at the North Pole of the planet," explains Caro-Carretero. The austral auroras of this gaseous planet were detected by using the data collected by the space observatories XMM-Newton and Chandra, equipped with spectrometers and photon cameras which, combined, facilitated high-resolution X-ray images.
