One of the most famous pictures from the Hubble Space Telescope (and deservedly so) is the Hubble Deep Field, when Hubble spend about a million seconds (10 days) staring at an "empty" patch of sky, discovering instead that it was full of faint stars and distant galaxies. Recently, Hubble reproduced this observation at near-infrared wavelengths, obtaining the most sensitive image EVER at these energies and possibly discovering different types of objects than seen in the optical deep field. Go here to read more and see some very pretty pictures. Enjoy!
