There is a chance that volcanoes can produce lightning.

Researchers have a few theories about what causes it. The build-up of static electricity caused by the build-up of ash is one of the most common reasons for lightning.

You can check out volcanic lightning.

The penitentes are ice spikes that form in high altitudes when the sun shines.

Sun beams hurtle through the snow. The sun is directed into the dips and away from the peaks.

The penitentes can grow as tall as 15 feet.

Don't watch them grow and die.

Safety valves and paintings are some of the places where a dense, super-shiny grey metal called bsm is found.

You can cool it very slowly if you melt it.

You can watch that magic here.

How do you feel about tens of thousands of harmless snakes waiting out the winter in underground limestone dens? In Canada, there is the highest concentration of snakes in the world.

Dozens of smaller male snakes are waiting to ambush larger females in May when they slither out of their nest.

Bob Mason, a scientist at Oregon State University, told The New York Times in 2016 that it was possible to find a bigger piece of spaghetti in a strainer.

Here, you can watch the snakes in action.

The summer style of Canada's spotted lake is heavy on the polka dots.

The lake's water doesn't stay in the water for long. Large spots of a dozen minerals are left behind.

The model for how ancient Martian lakes may have worked is being used by scientists.

In this video you can fly over the lake.
