    The first one day meeting on the protection of the sky and employment opportunities has been held
    “Future generations have the right to an unscathed, uncontaminated Earth, including the right to a clean sky”, This statement is included in UNESCO’s Declaration of the Rights of Future Generations. A message from José Domingo Fernández Herrera, Director General of the Fight against Climate Change and of the Environment of the Government of the Canaries reminded us during the opening ofthe “Ist meeting about the Protection of the Sky and Employment Opportunities” held yesterday, Tuesday in La Laguna. The meeting was organized by the Starlight Foundation, with the collaboration of the

    Red nuggets at the center of nearby galaxies
    The “Lambda Cold Dark Matter” (CDM) cosmological model is the current theory credited for reproducing the physics responsible for the formation and evolution of large-scale galactic systems in an accelerated expanding universe. In this context, the halos of CDM collapse and convert their energy reaching a state of equilibrium, allowing the formation of galaxies when the matter begins to cool. From an observational point of view, the behaviour of the luminous matter (stars and gas) is very different from that of dark matter. However, there are empirical relationships that reflect the

    Presentation of the book “Observing the Sun from Tenerife. An adventure above the sea of clouds”
    Presentation of the book “Observing the Sun from Tenerife. An adventure above the sea of clouds” “The latitude of the islands, Teide, and the trade-winds have contributed to the story of the Sun in Tenerife”. This phrase by solar physicist Manuel Vázquez Abeledo was noted during the presentation of his most recent book Observing the Sun from Tenerife. An adventure above the sea of clouds (just in Spanish) by another solar physics from the Instituto de Astrofísica de Canarias (IAC), his friend and colleague José Antonio Bonet, who gave a summary of it. The event took place last Friday at the

    Confirming new physics in space
    The interstellar medium is an excellent laboratory to test physical processes that cannot be reproduced in Earth-based laboratories. In this study several nebulae were used as a space laboratory to confirm the existence of an atomic process for which there was no previous experimental confirmation. In 2010, the existence of an atomic process that should occur frequently in astrophysical plasmas throughout the universe was theoretically proposed. The point is that this process — which is termed Rydberg Enhanced Recombination, or RER — had never before been detected, and it’s effectively

    Astronomers detect large amounts of oxygen in the atmosphere of a primitive star
    Scientists from the Instituto de Astrofísica de Canarias (IAC), in collaboration with the University of Cambridge and the University of California San Diego, detect large amounts of oxygen in the atmosphere of the "primitive star" called J0815+4729. This finding, reported in the journal The Astrophysical Journal Letters today, provides an important clue on how oxygen and other chemical elements were produced in the first generations of stars in the Universe. Oxygen is the third most abundant element in the Universe after hydrogen and helium. It is essential for all forms of life on Earth
