Wide-field view of the sky around a giant space blob

This visible-light wide-field image of the region around the giant Lyman-alpha blob LAB1 was created from photographs taken through blue and red filters and forming part of the Digitized Sky Survey 2. The blob itself lies at the centre of the image but, despite being huge and very luminous, it is so distant that it is too faint to be seen clearly on this picture. The field of view is approximately 2.9 degrees across.
