Image description: Mel Parsons from the Environmental Protection Agency (EPA) dives at the Tippo Bayou sampling station in the Mississippi Delta near Philipp, MS.
In what looks like pea soup, the diver was helping to collect ‘Sediment Oxygen Demand’ information. Sediment oxygen demand refers to how much oxygen is being used by organisms and plants in the sediment. The EPA uses these measurements to better understand the overall health of the water.
The Sloan Digital Sky Survey III (SDSS-III) has released the largest-ever three-dimensional map of massive galaxies and distant black holes, which will help astronomers explain the mysterious “dark matter” and “dark energy” that scientists know makes up 96 percent of the Universe.
This video is a fly-through of the SDSS-III galaxies mapped in the latest data release.

Image description: This is one of the first images taken by NASA’s Curiosity rover, which landed on Mars the evening of Aug. 5 PDT (morning of Aug. 6 EDT). It was taken through a “fisheye” wide-angle lens. As planned, the rover’s early images are lower resolution. Larger color images from other cameras are expected later in the week.
