    The Japanese ambassador to Spain visits the IAC and the Canary Observatories
    The Japanese ambassador to Spain, Kenji Kiramatsu, yesterday visited the Instituto de Astrofísica de Canarias (IAC) and the Canary Island Observatories, together with Masahiro Aoki, secretary to the Embassy, Yoshihiro Miwa, the consul of Japan in Las Palmas de Gran Canaria, and Josep Piqué Camps, President of the Council of the Spain Japan Foundation. Yesterday, they were received by Rafael Rebolo López, the Director of the IAC and Jesús Burgos, administrator of the General Services of the IAC at its headquarters in La Laguna. After a short visit, the delegation went up to the Teide

    Press release
    A step forward to solve the mystery of ultra-diffuse galaxies
    A study by the Instituto de Astrofísica de Canarias (IAC), led by researchers Nushkia Chamba, Ignacio Trujillo and Johan H. Knapen, reveals that the enigmatic ultra-diffuse galaxies, very low-luminosity and low-density star galaxies, are similar in size to dwarf galaxies. The results, which are published in the journal Astronomy & Astrophysics, provide new clues about the number and type of galaxies in our Universe and about the nature of dark matter.

    Are ultra-diffuse galaxies Milky Way-sized?
    Now almost 70 years since its introduction, the effective or half-light radius has become a very popular choice for characterising galaxy size. However, the effective radius measures the concentration of light within galaxies and thus does not capture our intuitive definition of size which is related to the edge or boundary of objects. For this reason, we aim to demonstrate the undesirable consequence of using the effective radius to draw conclusions about the nature of faint ultra-diffuse galaxies (UDGs) when compared to dwarfs and Milky Way-like galaxies. Instead of the effective radius

    Sucessful test of new technology which should help to discover “other Earths”
    A scientific team, led by the Max Planck Institute for Quantum Optics, with participation from the Instituto de Astrofísica de Canarias, confirms the high degree of precision of the new calibration system known as a “laser frequency comb” which could be the key to the detection of planets like the Earth. The study is published in the journal Nature Astronomy.

    New edition of "Girls who broke a glass ceiling while looking at the sky"
    With the aim of motivating interest in scientific and technological (STEM) careers among the younger girls, and to publicise the work of the women astrophysicists and engineers at the IAC, in 2017 the audiovisual series "Girls who broke a glass ceiling while looking at the sky" was initiated. The series, inspired in the project "No-Nancies" by the astrophysicist Pilar Montañés is included in the project "The return of Henrietta Leavitt: from school to a research career via the theatre", an initiative of the IAC in collaboration with the Spanish Foundation for Science and Technology (FECYT)
