In ancient times, the moon received oxygen synthesized by earth-plants
For the past 2.4 billion years, Earth's satellite has been receiving some oxygen from the planet. The moon reached the oxygen produced by the plants in the process of photosynthesis, say experts of the mission Lunar Orbiter Kaguya.
For a long time, oxygen particles from the Earth's atmosphere reached the moon. Evidence of the existence of such gas exchange was obtained from the study of lunar rocks made by the Kaguya orbital apparatus.
The sensors of the device have detected changes in the level of oxygen ions that invade it every time the Moon passes through the plasma layer of the Earth - a leafy region of a denser plasma in the lower field of the planet's magnetosphere.
Some of the isotopes of oxygen in the satellite are brought by the solar wind, including oxygen-16, but such isotopes are also found that are products of plant life.
