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.

At the beginning of last year, the newly released Astrograph STC (Sky Treasure Chest) of the Unit of Communication and Scientific Culture of the Canary Islands Institute of Astrophysics (IAC) captured the Andromeda Galaxy (M31). This Astrograph, located at the Teide Observatory (Izaña, Tenerife), aims to obtain astronomical images of great field and depth. Today, NASA has selected this image as Astronomy picture of the Day (APOD). Observatorio del Teide.

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. The discovery, made in a gigantic star-forming region of the Large Magellanic Cloud galaxy, has ‘far-reaching’ consequences for our understanding of how stars transformed the pristine Universe into the one we live in today. The results are published today in the journal Science.

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.
