Invited by Nature Astronomy, Cristina Ramos Almeida, researcher at the IAC, and Claudio Ricci, from the Institute of Astronomy of the Universidad Católica de Chile, publish in this journal a review of the most recent results on the material that obscures active galactic nuclei obtained from infrared and X-ray observations, their respective fields of research.

This picture of the Periades star cluster is the fifth photograh taken with the astrograph of the Unit of Communication and Scientific Culture (UC3) of the IAC, at the Teide Observatory, as an element of the Project “NIÉPCE: from the negative to the positive”, which will be an element of the exhibition “100 square moons”

The study, published in the Astrophysical Journal, is based on observations of the expanding remnant of Tycho’s supernova

The Cabildo of La Palma, the Town Council of Puntagorda, the Instituto de Astrofísica de Canarias and the TMT International Observatory have signed a framework agreement which indicates the principles and the areas of collaboration required to implement this scientific project on the island.

A team led by a researcher at the IAC and the University of La Laguna (ULL) has accurately measured the variation of oxygen abundance along the disc of our Galaxy.

The European Solar Telescope (EST) is a project led by the Instituto de Astrofísica de Canarias (IAC) to construct the largest solar telescope in Europe with a diameter of 4m, at one of the two observatories in the Islands. Its main purpose will be to study phenomena such as sunspots and solar flares, with unprecedented accuracy, and a resolution of a few tens of kilometres at the surface of the Sun. The EST will allow us to better understand the emission of large quantities of electrically charged material, which can cause problems with our systems of communications. The model of this
