Learning by Painting... The Moon is an astronomical body that orbits planet Earth and is Earth's only permanent natural satellite.
The Moon is thought to have formed about 4.51 billion years ago, not long after Earth. The most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body called Theia slammed into the planet, slinging large portions of its mantle out into space. In the aftermath, the gravity of Earth eventually gathered that rocky debris into the planetary body that would become the moon.
In May 2017 a new theory proposed an entirely new type of planetary object called the "synestia," which they described as "a huge, spinning, donut-shaped mass of hot, vaporized rock, formed as planet-sized objects smash into each other."
This theory is pretty similar to the impact model, but with some important differences. Instead of a glancing blow with a Mars-sized object breaking off chunks of the Earth, the impact positively vaporized our young planet, turning it into a rapidly spinning cloud of molten and vaporized rock. That's where our lunar neighbor is born. "The Moon forms inside the vaporized Earth at temperatures of four to six thousand degrees Fahrenheit and pressures of tens of atmospheres".
The physical exploration of the Moon began when Luna 2, called "the victory of the space", a space probe launched by the Soviet Union, made an impact on the surface of the Moon on September 14, 1959.
Prior to that the only available means of exploration had been observation from Earth by optical telescope invented by the italian Galileo Galilei in 1609.
The USSR pioneered the exploration of the Moon with a series of unmanned missions from 1958 to 1976.
NASA's Apollo program was the first, and to date only, mission to successfully land humans on the Moon, which it did six times.
Neil Armstrong's trail-blazing lunar jaunt is common knowledge. Since that iconic touchdown on July 20, 1969, only 11 people have dirtied their astro boots with moon dust.
The last time humanity set foot on the moon was 1972 when Pink Floyd releasing "Dark Side Of The Moon".
China will attempt the first soft landing of a spacecraft on the far side of the moon. No official date has been announced, but the mission is rumored for launch on December, with a landing in a month to lay a foundation for future lunar and deep-space exploration, including expanded missions to the lunar poles in the early 2020s by China.
But the next upcoming event is on Jan. 21, 2019 with a total lunar eclipse. In this case, the Earth will come between the sun and the moon in just the right way so that the shadow of our planet is cast entirely cast across the moon.
Waiting for the Moon, you can joint to my Master Class Lessons and paint the "Art side of the Moon" too.
