| Video Discription | New observations of our atmosphere calculate that it extends far beyond what we thought, encompassing the moon! This means that we've actually never left Earth's atmosphere. Here's what else these observations can tell us.

The denser dayside region of hydrogen is still rather sparse, with just 70 atoms per cubic centimeter at 60 000 kilometers above Earth’s surface, and about 0.2 atoms at the Moon’s distance." The edge of space: Revisiting the Karman Line https://www.sciencedirect.com/science/article/pii/S0094576518308221?via=ihub "A number of these authors suggest that the large variations with time of atmospheric properties make it futile to locate a true boundary of space based on physical arguments. In this paper I will argue the contrary: there is a moderately-well-defined boundary of space, it coincides with the Karman line as originally defined, and that line is close to 80 km, not 100 km." Exosphere - overview https://scied.ucar.edu/shortcontent/exosphere-overview "Not all scientists agree that the exosphere is really a part of the atmosphere. Some scientists consider the thermosphere the uppermost part of Earth's atmosphere and think that the exosphere is really just part of space. However, other scientists do consider the exosphere part of our planet's atmosphere." ____________________ Elements is more than just a science show.
