This project, in which the Instituto de Astrofísica de Canarias (IAC) is collaborating, has made a map with 300 galaxies close to the Milky Way, which they have classified on the basis of the way the stars are moving, rather than using the morphological classification used until now.

An international team of astronomers led by Giuseppina Battaglia, researcher at the Instituto de Astrofísica de Canarias (IAC), finds signs that the outer halo of the Milky Way contains stellar remains of massive dwarf galaxies that were devoured by our own.

An international team of astronomers with participation of researchers at the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL) has revealed an ‘astonishing’ overabundance of massive stars in a neighbouring galaxy.

Several telescopes of the Canary Island Observatories are studying this controversial star in a coordinated campaign involving over a hundred professional and amateur astronomers throughout the world, among them researchers at the IAC and the ULL.

An International team with participation by researchers with close links to the Instituto de Astrofísica de Canarias and the University of La Laguna, obtains the first clear observational evidence that the mass of the supermassive central black hole in a massive galaxy affects the formation of new stars during its lifetime.

Researchers at the Instituto de Astrofísica de Canarias (IAC) have identified, using the Gran Telescopio de Canarias (GTC) a star which is a key to the formation of the first chemical elements in the Galaxy. The results of this research are published today in the scientific journal The Astrophysical Journal Letters.
