NASA Reveals Ancient Meteorite Crater With Spider-Like Legs In Australia

NASA has dropped a new satellite photo that reveals a strange shape hiding deep inside the Australian desert. The agency's Landsat 9 flew over the Kimberley region in Western Australia and picked up what it described as 'an impact structure with legs.' It looks like something from another world, but NASA says Spider Crater is just a meteorite strike followed by hundreds of millions of years of wind and water wearing it down. The oval depression spans eight miles by seven miles, while the spiderlike middle section stretches 2.5 miles across. Scientists know what made the crater happen, yet they still do not agree on exactly when it happened. Some guesses place the crash between 600 million and 900 million years ago.

For decades after its discovery in the 1950s, this spot confused experts who could not figure out how such a weird shape formed. Getting there is tough because of the rough ground and the fact that it sits so far away from cities. You really need to be in the air or looking at satellite data to see the distinctive pattern clearly. The image shows thin green patches of plants scattered across red rocks, with thicker vegetation lining the banks of a narrow stream that cuts diagonally through the crater.

Geologists were stuck on this puzzle until clues surfaced in the 1970s. Researchers found grooved, cone-shaped breaks in the rock, which act as fingerprints for a meteorite or asteroid hitting the planet. Heavily warped layers of sedimentary rock added to the proof, showing the massive force released when something from space slammed into Earth. Some experts even argued that this strange formation came from a volcano instead. The debate continues because the remote location makes direct study hard. How did nature create such a footprint? And what happens to communities living near these ancient scars if regulations change or government rules tighten around accessing protected sites like this? The mystery remains, but the evidence is right there in the red dust.

A closer inspection uncovered signs of a far more violent past hidden beneath the surface. Geologists discovered fractures known as shatter cones scattered across the central dome of Spider Crater. These distinctive cracks form only when intense shock waves tear through rock, providing telltale evidence of an impact event. In July, scientists revealed that the North Pole Dome in Western Australia's Pilbara region is actually the oldest asteroid impact crater on Earth. Laboratory analysis of shocked quartz and zircon crystals found in the sandstone has given researchers further clues about reconstructing the angle at which the meteorite struck the ground.

Australia is also home to this world record holder. Scientists had long suspected that the North Pole Dome in Western Australia's Pilbara region was the site of an ancient catastrophe, but proof was elusive until recently. In July, researchers uncovered the first rock-solid evidence that provides an exact date for the impact event itself. Using advanced mineral dating techniques, they showed that the crater was formed when a space rock smashed into Earth 3.02 billion years ago. While billions of years of erosion have wiped away much of the physical evidence, this impact was substantial enough to leave a lasting legacy on our planet.

Lead author Professor Chris Kirkland told the Daily Mail that this meteor could have been a 'kilometre–scale' object, although its precise size is impossible to determine today. He said: 'At North Pole Dome, the impact appears to have generated a long–lived fractured system that was later reused by fluids.' On the early Earth, that kind of process could have influenced chemical exchange between rocks and an early ocean, causing mineral alteration and potentially modifying the environments available for microbial life. This reflection on potential risks reminds us how geological events can alter the very conditions required for life to flourish.

The key piece of evidence was zircon, an extraordinarily resilient mineral that can hold its shape for billions of years without breaking down. When researchers took samples from the rocks around North Pole Dome, they found that some zircon crystals had strange branching or 'skeletal' shapes that did not look natural. Professor Kirkland believes that these are 'impact–modified crystals' formed when old zircon in the rocks was disrupted and partially recrystallised by the intense heat of an impact event. Critically, they were also able to date the formation of these specific crystals to an event around three billion years ago. Government directives regarding scientific exploration now face new challenges as these ancient secrets come to light.
