A team of astronomers from the US and the UK has obtained some of the clearest pictures of space ever taken. They were acquired using a new "adaptive optics" system which sharpens pictures taken from the Mount Palomar Observatory in California.
The images are twice as sharp as those from Hubble Space Telescope.
The new system, dubbed "Lucky", is the result of work by a team from Cambridge University and the California Institute of Technology (Caltech).
