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

La Fundación CajaCanarias organiza la octava edición de su Foro Enciende el Cosmos, que este año volverá a contar con la participación de destacados científicos e investigadores de reconocido nivel nacional e internacional. Esta iniciativa de carácter divulgativo pretende expandir, desde la exploración científica, la comprensión del Universo en su conjunto, relacionando el pasado con el presente y con una clara búsqueda de respuestas de cara al futuro. El programa se divide en tres sesiones, a celebrar los días 13 de febrero, 20 de marzo y 10 de abril, en el Espacio Cultural CajaCanarias de

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
