The spaceship Pentallion races towards the sun, in this gorgeous painting of a scene from the Doctor Who episode "42." A signed print of this artwork is up for auction, with the benefits going to young heart-transplant patients.
Regular Doctor Who concept artist Peter McKinstry did this artwork for Doctor Who Files Magazine, so it's not official concept art. But it's still utterly gorgeous, and there are only two bids in the auction so far. It's raising money for Art for Hearts, a project that supports the heart transplant team at Great Ormond Street Hospital. You can bid on it here, although I'm not sure if it's open to people outside the U.K. [eBay]
