Images bridging four decades show where Switzerland's largest glacier and its neighbors have been losing ice.

As winter turned to spring, ice cover on the lake diminished to reveal colorful billows of sediment and phytoplankton.

The asteroid that smashed into northern Australia and caused the Amelia Creek impact structure transformed mountain ridges in the blast zone.

Repeated land divisions over centuries have created a complex mosaic of ribbon-like fields in southern Poland.

A salt-encrusted landscape surrounds the Colorado River where it once emptied into the Gulf of California.

The sheer power of an asteroid impact that gouged a three-mile-long trough in the ground and buckled local rocks has been revealed in a NASA satellite image.

Estimated to have been 700⁘1,300 feet across, the space rock slammed into what is today a mountain range in Australia 's Northern Territory some 600 million years ago.

"On February 3, 2025, the Operational Land Imager (OLI) on Landsat 8 captured this view of the impact site, an area called the Amelia Creek Impact Structure," NASA said. "The long, narrow shape of the crater and the pattern of regional deformation are signs that the asteroid struck at an extremely oblique (shallow) angle."

According to the space agency, the impact gouged a "canoe-shaped trough" some three miles long and 0.6 miles wide into the ancient landscape.

Based on analysis of satellite measurements, the collision deformed sedimentary and volcanic rock layers as far as 6.2 miles to the north and south of the impact crater, while leaving the east and west relatively unscathed.
