The Instituto de Astrofísica de Canarias (IAC) has received and will appeal the sentence, which is not firm, related to the cancelling of the concession for the land which should house the Thirty Metre Telescope (TMT) in La Palma. In 2019 the Cabildo of La Palma, following approval by a full session of the Town Council of Puntagorda, and a detailed environmental study, conceded to the IAC the land on which the TMT could be built. This concession was made conditional on the decision within a few years, which have not yet expired, that the International TMT Observatory would decide to build it

In 1998, the journal Nature published a seminal letter concluding that the mysterious polarization signal that had been recently discovered in the light emitted by the sodium atoms of the solar atmosphere implies that the solar chromosphere (a very important layer of the solar atmosphere) is practically unmagnetized, in sharp contradiction with common wisdom. This paradox motivated laboratory experiments and theoretical investigations, which instead of providing a solution, raised new issues and even led some scientists to question the quantum theory of radiation-matter interaction. In an

La II edición de este proyecto de divulgación científica mostrará la belleza y riqueza del patrimonio cultural del concejo de Allande (Asturias) a través de la Astronomía, del 20 al 22 de agosto. Tras el éxito de la primera edición, el equipo multidisciplinar de “Allande Stars” volverá a subirse a su furgoneta de estrellas los días 20, 21 y 22 de agosto de 2021 para llevar la Ciencia a la zona rural. Con la misma pasión e ilusión que el año anterior, sus colaboradores recorrerán el concejo de Allande impartiendo talleres diurnos y nocturnos relacionados con la Astronomía y la Astrofísica

Under the title "Our home in the cosmic ocean", the seventh edition of the international summer course "Astronomy Education Adventure in the Canary Islands" has had 136 participants from 30 countries who have been trained in the latest discoveries about the Solar System and in the techniques and tools they can use to investigate it with their students. Several of the lectures from the course, given by researchers and science communicators, have just been published on the IAC's YouTube channel. For the seventh consecutive year, the Instituto de Astrofísica de Canarias (IAC) and NUCLIO, in
