An international scientific team, including the Instituto de Astrofísica de Canarias (IAC), has detected distortions in the brightness of a galaxy's disc that could be explained by the gravitational effect of an unknown neighbouring galaxy. Named GTC-1, the satellite galaxy was discovered using ultra-deep images obtained with the OSIRIS camera of the Gran Telescopio Canarias, located at the Roque de los Muchachos Observatory in La Palma. The finding provides a possible explanation for a puzzle about way the light fades out at the edges of galaxy disks, a mystery that has bothered the

From 25 to 28 July, the workshop "China-Spain collaboration on astronomical high-resolution spectroscopy" will be held in Fuencaliente (La Palma). Its aim is to consolidate scientific collaboration between China and Spain in astronomy, especially in the context of the technological development of the CHORUS instrument and its applications in different fields of astrophysical research. CHORUS (Canary Hybrid Optical high-Resolution Ultra-stable Spectrograph) is a high spectral resolution ultra-stable spectrograph for the Gran Telescopio Canarias (GTC or Grantecan) being developed by the

9 institutions from 7 European countries today signed the documents for this organization, which will prepare the way towards the future construction of the European Solar Telescope (EST) One of the main aims of the EST is to improve our understanding of the Sun by observing its magnetic fields in unprecedented detail Representatives from 8 institutions in 7 European countries, among which are the Consejo Superior de Investigaciones Científicas (CSIC) and the Instituto de Astrofísica de Canarias (IAC) this morning in Santa Cruz de Tenerife, signed the founding documents of the Canary

International research led by the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has found the first evidence of a massive galaxy with no dark matter. The result is a challenge to the current standard model of cosmology. The study is published in the specialized journal Astronomy and Astrophysics. A team of scientists, led by the researcher at the IAC and the University of La Laguna (ULL) Sebastién Comerón, has found that the galaxy NGC 1277 does not contain dark matter.This is the first time that a massive galaxy (it has a mass several times that of the
