A 2017 astronaut photo shows two sets of solar evaporation ponds alongside the Colorado River. The stripy structures are used to refine potassium chloride, or "potash," which is mined nearby.

China's Tianzhou-10 mission just delivered embryo-like structures made from living stem cells to the Tiangong space station. Experiments could shed light on how radiation and microgravity affect human reproduction.

A 2015 satellite photo shows a series of golden tendrils surrounding Ghana's Lake Bosumtwi, which is considered sacred to the local Asante people. The lake and its surroundings were shaped by a massive meteor impact around 1 million years ago.

Multiple videos show a rare "fireball" meteor breaking apart with a flash of emerald light over the erupting Mount Mayon. Initial reports suggested that the falling space rock hit the volcano, but this was untrue.

Researchers have uncovered an unexpected phenomenon, dubbed the Zwan-Wolf effect, squeezing plasma "like toothpaste" in Mars' upper atmosphere. This effect, which also happens on Earth, was thought to be impossible on the Red Planet.
