Astronomers Find First Earth-like Planet in Habitable Zone
Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. Using the ESO 3.6-m telescope, a team of Swiss, French and Portuguese scientists discovered a super-Earth about 5 times the mass of the Earth that orbits a red dwarf, already known to harbour a Neptune-mass planet. The astronomers have also strong evidence for the presence of a third planet with a mass about 8 Earth masses. Copyright ESO www.eso.org

Hubble Deep Field: The Most Imp. Image Ever Taken (Redux)
This is the latest incarnation of the HDF video. The narration has been edited to include research from a paper in Physical Review Letters (2004) which puts the size of the universe at 46.5 billion light years, not 78 billion as I originally stated. In the video narration, I round that value up to 47 billion light years.
