Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesIt is easy to imagine the moon as an atmosphere-less hunk of rock orbiting Earth. However, while lacking breathable air, our planet's loyal natural satellite companion does have a thin and wispy atmosphere.
Scientists first began to suspect that the space-rock assault on the moon was responsible in part for generating the exosphere whenThis led them to highlight two processes regenerating the exosphere. The first was impact vaporization, the other was"ion sputtering." This latter process occurs when high-energy charged particles from the sun, known as the"," strike the lunar surface and impart energy to atoms. This also causes those atoms to be flung into the exosphere.
"With impact vaporization, most of the atoms would stay in the lunar atmosphere, whereas with ion sputtering, a lot of atoms would be ejected into space," Nie said.
