. In this picture, three different filters (r' i' and z') have been combined to show how the quasar (indicated by the arrow) is very red compared to stars or galaxies in the field. The intense red color is a good indicator that the object is a very distant quasar. Provided by CFHT

. Hubble's view of the Carina Nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. NASA/ESA/N. Smith/STScI/AURA

. The Canada-France-Hawaii Telescope (CHFT) is based on an equatorial mount design, with one axis of rotation set parallel to the axis of Earth's rotation. A record-breaking black hole was found from a new survey for distant quasars called the Canada-France High-z Quasar Survey (CFHQS), which uses the MegaCam imager on the MegaPrime focus of the CFHT.
