Sky in Diamonds

Kilauea volcano in Hawaii has been active for almost two months. It turned out that besides fear and destruction, the volcano can produce something beautiful. Together with the lava, small crystals of the semiprecious stone olivine erupted onto the earth!

Olivine is a very common mineral, the most abundant in the Earth's mantle. It is the volcanic activity that usually helps the olivine, melted in the magma, to come to the surface.

In space, metal sticks together

If you put two pieces of metal together in space, they will stick together. This process is called cold welding. Atoms on the surface of metals don't "feel" the difference between their metal and their neighbor. And they form similar bonds with them.

On Earth, this is prevented by oxygen, which is found in almost every corner of our planet. And oxidation prevents them from sticking together.

Astronauts, who bring instruments from Earth, are not afraid of "sticking" anyway. After all, every instrument retains an oxide layer. Any additional layer, be it gas or dirt, prevents sticking.
