Here and There
Largest Photo Map of Moon (Sky at Night Magazine)
Eleven British amateur astronomers stitched together their photos of a 9 day Moon. There are 288 panes and they have detail at 0.6 miles wide.
Channel Islands of California and Comet Impacts (U or Oregon)
Comet impacts about 13,000 years ago could have led to mass extinctions of North American life. Telltale soot and diamonds have been discovered.
Asteroid or Comet Strike on Jupiter (JPL)
Australian Anthony Wesley discovered an impact site on Jupiter. He found it on the anniversary of the Shoemaker-Levy comet smash.

Strange Hyperactive Galaxies of Long Ago (Hubblesite)
These are small galaxies but with stars moving very fast. So they are massive galaxies. They don't fit well with astronomical generalizations about the early universe. Such galaxies aren't seen in our more recent and local universe.
Bright Spot on Venus (New Scientist)
Amateur astronomer, Frank Melillo of Holtsville, NY, first found the spot. The spot may have come from extremely powerful eruptions. It may, instead, be from solar particles interacting with the Venusian atmosphere. Then, too, it could be bright concentrations of turbulence.
