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

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

The IAC researcher Susana Iglesias-Groth has discovered the existence of tryptophan, an amino acid essential for the formation of proteins and the develoment of living organisms, within a stellar system in the Perseus Cloud. She did this using data from the Spitzer Space Observatory. The results of this finding are published in the journal Monthly Notices of the Royal Astronomical Society. Tryptophan is one of the 20 amino acids considered essential for the formation of proteins, which are key macromolecules for the development of life on Earth. This amino acid has many spectral features in
