Landsat 5 acquired this image on July 20, 2011. Vegetation is green, bare ground is brown, water is blue, roads and buildings are light grey and snow is white. This is a true color image using bands 3, 2, and 1.
Lightning strikes over the Puyehue volcano, over 500 miles south of Santiago, Chile, Monday June 6. Authorities have evacuated about 3,500 people in the nearby area. The volcano was calm on Monday, two days after raining down ash and forcing thousands to flee, although the cloud of soot it had belched out still darkened skies as far away as Argentina.

Though the above image may resemble a new age painting straight out of an art gallery in Venice Beach, California, it is in fact a satellite image of the sands and seaweed in the Bahamas. The image was taken by the Enhanced Thematic Mapper plus (ETM+) instrument aboard the Landsat 7 satellite. Tides and ocean currents in the Bahamas sculpted the sand and seaweed beds into these multicolored, fluted patterns in much the same way that winds sculpted the vast sand dunes in the Sahara Desert.

"Supermoon": Biggest Full Moon in 18 Years Saturday
The monthly full moon always looks like a big disk, but because its orbit is egg-shaped, there are times when the moon is at perigee—its shortest distance from Earth in the roughly monthlong lunar cycle—or at apogee, its farthest distance from Earth.
Likewise, because the size of the moon’s orbit varies slightly, each perigee is not always the same distance away from Earth. Saturday’s supermoon will be just 221,566 miles (356,577 kilometers) away from Earth. The last time the full moon approached so close to Earth was in 1993, according to NASA.
An aerial photo, released by China’s Xinhua news agency on July 17, 2010, shows an oil slick floating off the coast of Dalian, China. Efforts were under way to contain and clean up a large oil slick after pipeline explosions at the northeastern Chinese port sent greasy black plumes into the ocean, state media reported.

I recorded an episode of Dangerous Encounters about sixgills, because they’re my favourite shark ever - followed by oceanic whitetips and hammerheads - and I’m barely getting through it. It’s hosted by Brady Barr, a herpetologist, who has the most annoying way of speaking.
He EMPHasizes EVERYOther word, and shouts/screams constantly. Why does this doofus have a show? Why does he get to go in a mini-sub and hand out with sixgills? Ugh.
This digitally enhanced satellite image captured by DigitalGlobe on June 15, 2010 and released June 17, 2010 shows part of the oil spill clean up effort in the Gulf of Mexico. This image leverages the different sensor bands of DigitalGlobe’s WorldView-2 satellite to highlight the oil and dispersant. (REUTERS/DigitalGlobe)
On May 24, 2010, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this false-color, high-resolution view of the very tip of the Mississippi River Delta. Ribbons and patches of oil that have leaked from the Deepwater Horizon well offshore are silver against the light blue color of the adjacent water. Vegetation is red.
