KEBIRA IMPACT CRATER: Sometimes asteroids miss, and sometimes they don’t. Planetary scientist Farouk El-Baz of Boston University has just announced the discovery of a 19-mile-wide impact crater in the Sahara desert. He named it Kebira, an Arabic word meaning “large.”
Kebira is so large that it is actually difficult to see from ground level. Satellite images show it better. Using Landsat 7 data, Frank Reddy of Astronomy Magazine created this 3D anaglyph:

“Desert sands, wind, and ancient rivers have eroded the dark, 100-million-year-old sandstone, but the crater’s rings and central uplift still stand out,” says Reddy. “El-Baz thinks this is the source of a yellow-green desert glass found throughout the region.
