El Instituto de Astrofísica de Canarias participa una vez más en la Feria de la Ciencia de La Orotava que este año cumple su XXI edición. Se trata del encuentro de divulgación más longevo de Canarias y que en esta ocasión está dedicada a nuestra estrella: el Sol. Esta edición se celebrará el próximo domingo, 10 de noviembre, en la Plaza de la Constitución de La Orotava, entre las 10:30 y las 18:30 horas. El IAC participará en esta feria con un stand donde ofrecerá actividades coordinadas por el equipo de Divulgación de la Unidad de Comunicación y Cultura Científica (UC3) del IAC junto a

The Instituto de Astrofísica de Canarias (IAC) in collaboration with the University of Geneva (Switzerland), the University of Osaka (Japan), and the University of Zhejiang (China) has made a key contribution to a more precise measurement of the expansion of the Universe. This is because they have made an improvement in the precision of the calculation of the scale of the universe in its early stages using the analisis of the distribution of gas in intergalactic space, measurements which reach back to epochs between 10,000 and 12,000 million years ago. This result comes from the análisis of

The single star nearest to the Sun is called Barnard’s star. A team of researchers led by the Instituto de Astrofísica de Canarias (IAC), has recently detected a ‘sub-Earth’ orbiting it. This exoplanet, called Barnard b has at least half the mass of Venus and orbits rapidly around its star, so that its year lasts only a little over three Earth days. This new exoplanet is sixteen times nearer to Barnard’d star than Mercury is to the Sun, and has a surface temperature close to 125oC, so it does not have liquid water on its surface. This discovery, led by the IAC in collaboration with a number
