SUMMARY:Entering uncharted territory: the extremely low surface brightness 
 Universe
DESCRIPTION:Entering uncharted territory: the extremely low surface brightn
 ess Universe\nDr. Ignacio Trujillo\n\nCurrent state-of-the-art imaging sur
 veys deliver images with limiting surface brightness of 26.5 mag/arcsec^2.
  This depth is around 100 times fainter than the brightness of the sky in 
 professional observatories. This view of the Universe is the basis of most
  of our visual understanding of the closest (galactic and extragalactic) o
 bjects. However, going deeper is absolutely mandatory if we want to unders
 tand a plethora of astrophysical phenomena that manifest themselves at low
 er surface brightness limits. To understand from the smallest scales of ou
 r local Galactic cirrus to the huge extensions of the intra-cluster light 
 of massive galaxy clusters I will present in this talk two important steps
  forward conducted here at the IAC.  The first one is The IAC Stripe8
 2 Legacy Project: a public survey for the astronomical community which inc
 ludes 275 square degrees in 5 optical bands reaching 28.5 mag/arcsec^2 dep
 th. The second one is the deepest ever imaging of the nearby Universe: 8h 
 of GTC time on the near UGC00180 galaxy reaching a limiting surface bright
 ness of 31.5 mag/arcsec^2 (100 times deeper than traditional surveys). A l
 arge amount of unexpected discoveries emerge in these unprecedented set of
  images.
