lava
The temperature of lava, depending on its composition, can range from 700 to 1,200 °C.
Beyond Earth, lava can reach even higher temperatures; the record holder is Io, Jupiter's moon, where satellites have recorded lava flows with an average temperature of 1,300 °C (2,370 °F).
Moon
The Moon has a residual atmosphere whose pressure is 3×10-15 bar.
Its entire atmosphere weighs only 10 tons.
Graphene
The publication of a groundbreaking experiment on two-dimensional graphene, as well as the description of a surprisingly easy method of obtaining it, triggered a real “graphene gold rush.”
Research has expanded and divided into many different subfields, examining various unique properties of graphene-quantum mechanics, electrical, chemical, mechanical, optical, magnetic, etc.
Nicotine
The name nicotine comes from the name of the French physician Jean Nicot, who recommended tobacco as a medicine in the 16th century.
Nicotine was first isolated in 1828, and its chemical structure was discovered in 1843. Nicotine was first obtained through a chemical process in 1904.

The largest crater in the Solar System is located on the surface of Ganymede, Jupiter’s largest moon.
The crater has a diameter of 15.600 kilometers and was discovered on 7th August 2020. So far it has not been named.
