    Eva Villaver participa en la presentación del libro ‘Eclipses. El Sol y sus eclipses en la ciencia, la historia y las artes’
    Los seres humanos han seguido los movimientos regulares del Sol y la Luna desde las civilizaciones más remotas y a lo largo y ancho del planeta Tierra. Ocasionalmente, el Sol se oscurecía o la Luna se teñía de rojo y esto dio lugar a múltiples interpretaciones más o menos disparatadas. A menudo estos eventos se consideraron como signos de malos augurios, aunque también inspiraron mitos de carácter más lúdico e incluso amoroso. Con ocasión de los tres eclipses solares que serán visibles desde España en 2026, 2027 (totales) y 2028 (anular) y que constituyen una tríada astronómica excepcional

    A new model provides an explanation for the tiny ‘nanojets’ observed on the Sun
    An international team of researchers led by the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL), has unveiled a breakthrough explanation for the origin of tiny, jet-like plasma ejections in the solar atmosphere, known as “nanojets.” These elusive events which are recently discovered by the NASA’s solar telescopes are thought to play an important role in heating and sustaining the solar corona at temperatures above one million Kelvin. Why Study Nanojets? For decades, solar physicists have been puzzled by the so-called “coronal heating problem.” While the Sun

    The IAC takes its space technology to Space Symposium 2026 and signs a collaboration agreement with LASP at the University of Colorado
    The Instituto de Astrofísica de Canarias is taking part in the 41st edition of the leading international space forum, held in Colorado Springs from 13 to 16 April, within the Spain Pavilion organised by ICEX alongside 16 other organisations from the sector. The Instituto de Astrofísica de Canarias (IAC), through IACTEC Space, its department dedicated to the development of technology for small satellites, took part this week in Space Symposium 2026, held in Colorado Springs, Colorado, USA, from 13 to 16 April. The event, organised by the Space Foundation and now in its 41st edition, is the

    Appraising the Necklace: A post-common-envelope carbon dwarf inside an apparently carbon-poor planetary nebula
    The Necklace nebula is a bipolar, post-common-envelope planetary nebula, the central star of which has been shown to have a dwarf carbon star companion. We aim to understand the origins of the Necklace and its dwarf carbon central star. We study the carbon abundance of the nebula through far-ultraviolet spectroscopy obtained with the Hubble Space Telescope. Furthermore, through simultaneous modelling of multi-band light and velocity curves, we attempt to constrain the parameters of the central star system. Puzzlingly, we find that the region of the inner nebula observed with the Hubble Space
