An international team, in which the Instituto de Astrofísica de Canarias participates, has succeeded in mapping for the first time the three-dimensional structure of the atmosphere of an exoplanet, that is a planet beyond the Solar System. This research, published today in Nature , has been able to discover very strong winds that carry chemical elements such as iron and titanium, which create certain weather patterns through the planet's atmosphere. This mapping opens the door to more comprehensive and detailed studies of the chemical composition and climate of other planets. Enric Pallé
The solar corona—the outermost layer of the Sun’s atmosphere—is extremely hot and very low in density. One of the main challenges in solar physics is understanding why the corona reaches temperatures of over a million degrees. This heating is believed to be closely related to the Sun’s magnetic field. However, quantifying the coronal magnetic field is difficult because the light emitted by the corona is extremely faint, and its polarization signals, which encode the information on the magnetic field, are subtle. Thanks to recent advances in technology, telescopes like the Daniel K. Inouye
