(PHYSorg.com Space & Earth)

This image was captured by the NASA/ESA Hubble Space Telescope`s Advanced Camera for Surveys (ACS), a highly efficient wide-field camera covering the optical and near-infrared parts of the spectrum. While this lovely image contains hundreds of distant stars and galaxies, one vital thing is missing-the object Hubble was actually studying at the time!
