The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite took the images that make up the mosaic during various passes over the North Pole on Aug. 6, when the storm was swirling over the middle of the Arctic Ocean.

Evidence of a crash
Measuring about 15 miles (25 kilometers) across, the formation was named the Prince Albert impact crater after the peninsula where it was discovered. Researchers don't know exactly when it was created, but evidence suggests the crater is between 130 million and 350 million years old, according to a statement from the University of Saskatchewan.

Ernesto hits the Yucatan
As its center has moved over land, Ernesto has steadily weakened and now has winds of 50 mph (85 kph). But while its winds have weakened, it has still produced considerable rain.

More than a century coming
The eruption was a short-lived phreatic one, New Zealand volcano monitoring authorities said. hreatic eruptions are stream-driven eruptions that happen when water beneath or above the ground is heated up, potentially causing it to boil and "flash to steam," creating an explosion, according to the U.S. Geological Survey.

In the black-and-white photograph, the landscape is peppered with glowing lines that resemble the simple shapes of clouds one might see in a child's drawing ? the outlines of burns that officials say cover up to 90 square miles (233 square kilometers) of eastern Siberia, but that actually may be far more widespread.

Perito Moreno is perhaps the region's most famous glacier because it periodically cuts off the major southern arm (known as Brazo Rico) of Lake Argentino, by forming a natural dam with its ice tongue; this prevents water from transferring between the two bodies of water.
