    The first results of the BEARD project explain the survival of our Galaxy
    The international BEARD project, led from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), has used data from several telescopes at the Roque de los Muchachos Observatory, and computer simulations to explain how galaxies similar to the Milky Way have managed to survive the most violent stages of the history of the Universe. The present model for the evolution of the universe predicts an epoch dominated by important mergers of galaxies some ten thousand million years ago. “It’s a case of violent interactions, in which it is foreseeable that weak structures

    IAC y ULL led the identification of the longest orbital period exoplanets among those transiting young stars
    An international collaboration of astronomers led by the Universidad de La Laguna (ULL) and Instituto de Astrofísica de Canarias (IAC) has identified two intriguing, humongous but light planets orbit ing HD 114082. This star is only 15 million years old, this is, much younger than the Sun (4.6 billion years old) , spin s 15 times faster , has 28% more mass , and is about one thousand degrees hotter and almost four times more luminous. Its planets receive about 200 times more light and heat than Jupiter. The study, which involved separating the faint planetary signal from the stellar one
