Ultra-faint dwarf galaxies, among the tiniest and faintest galaxies known, may hold the key to understanding one of the Universe’s biggest mysteries: the true nature of dark matter. A new study reveals that even a single collision between dark matter particles every 10 billion years — roughly the age of the Universe — is enough to explain the dark matter cores observed in these small systems. These galaxies, which contain only a few thousand stars, are dominated by dark matter and have relatively simple evolutionary histories. That makes them ideal cosmic laboratories for testing theoriesAdvertised on -

During October, the Adaptive Optics System team at the Gran Telescopio Canarias (GTCAO) of the Instituto de Astrofísica de Canarias (IAC), in collaboration with the technical team at the Gran Telescopio Canarias (GTC or Grantecan), successfully completed the integration of the GRANCAIN instrument into the world's largest optical-infrared telescope. The installation was carried out at the GTCAO outlet on the telescope's Nasmyth B platform, a key step in initiating performance testing of the new adaptive optics system. This is the first scientific instrument to operate using the GTC's adaptiveAdvertised on
