Resembling splotches of yellow and green paint, salt-encrusted seasonal lakes - the largest of which is Lake Teague - dot the floor of the Shoemaker impact crater in this enhanced satellite image.
Formerly known as the Teague Ring, the structure was formed about 1.7 billion years ago and is currently the oldest known impact site in Australia.
