Highlights include what is billed as the first photo of the Ebola virus, a Periodic Table of Elements, and the Genome Sequence Database. Hubble researchers are intrigued by the fact that the quasars studied do not appear to have obviously damaged the galaxies in which they live. The photos are of galactic objects 1.4 and 1.5 billion light years from Earth.
Photos are in black and white and color, and at various resolutions.
The photos are accompanied by an explanatory caption, background material on quasars, and an MPEG model of a quasar.
