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.

Earth’s Atmosphere Stretches Out To The Moon – And Beyond
“The new study revealed that sunlight compresses hydrogen atoms in the geocorona on Earth’s dayside, and also produces a region of enhanced density on the night side. 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
“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
“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.”
