It seems that the Moon once had an atmosphere


According to a new research, about 3 to 4 billion years ago, our Moon may have had an atmosphere, and according to the researchers, it would have arisen due to multiple volcanic eruptions that devastated the planet during that time, concentrating gases into the atmosphere so densely that they could not escape into space.

The surface of the Moon is studded with impact craters filled with volcanic basalt, which was formed when magma plumes from the moon’s interior erupted, creating currents of magma.

When the astronauts returned from the Apollo missions, they brought some samples of this soil of magmatic origin to Earth, and we know that in their composition, there was carbon monoxide and other gaseous components such as sulfur, and even some bases for the formation of water.

At the time our moon does not have any kind of atmosphere, due largely to the fact that it does not have a magnetic field and mass sufficiently strong to withstand an atmosphere, and due to that, any atmosphere that eventually began to form in our natural satellite, would quickly vanish into space thanks to the solar winds.

The team made this discovery after an analysis of the gas composition of the samples, through which it was possible to calculate the amount of gas that eventually rose and accumulated in the atmosphere, forming the said transition atmosphere, and found that with the peak of atmospheric activity that happened about 3.5 billion years ago, the Moon’s atmosphere reached its highest density.

The atmosphere was later maintained for about 70 million years, before it began to fade, escaping into space. During this period, the Moon was about three times closer to Earth, and probably appeared to be much larger when viewed in the Earth’s sky.

Scientists also believe that volatile gases may have been frozen in the area of the moon’s poles, and this information is extremely important in planning future missions to the moon, since poles could be a possible source of drinking water and to create plantations and may also contain volatiles that can be used as fuel for missions on the surface of the Moon, and even for missions beyond the Moon, since what is already there no longer needs to be transported from Earth, opening space for different types of cargo in the space shuttle.
