There’s a hexagonal storm on Saturn.
Here on Earth, we’re used to seeing long, oval hurricanes and conical tornadoes forming from the sky. But since everything is different in space, this applies to storms as well. The giant planet is dealing with a storm at its north pole for at least 40 years.
The storm is strangely shaped like a hexagon, maybe due to the planet’s turbulent gas or the ‘zonal jets’ present in that area, as recent research has shown.
Cold welding.
Combining two pieces of metal here on Earth requires heat. But when it comes to space, anything is possible. The phenomenon is called cold welding, and no heat or any action at all for that matter is required for fusing two metal pieces in space.
Cold welding happens when two (or more) metal pieces slide over each other, causing their protective oxide layers to erode, the same layer that’s stopping them from fusing here on Earth.
When the protective layer disappears, the electrons from the metal pieces combine, resulting in one.
