Gosses Bluff Impact Crater, Northern Territory, Australia

June 15, 2003
This image shows Gosses Bluff, an impact crater sandwiched between the Macdonnell Range to the north and the James Range to the south in Australia’s Northern Territory —- it is about 160 km west of Alice Springs. It is one of the most studied of the Australian impact craters. The impactor, an asteroid or comet, was probably about 1 km in diameter and crashed into the earth about 142 million years ago. The isolated circular feature within the crater consists of a central ring of hills about 4.5 km in diameter. The grayish feature surrounding the inner ring probably marks the original boundary of the outer rim.
