EARTH'S ATMOSPHERE REACHES BEYOND THE MOON
Hey Space Placers!
Here's some big news about our home planet - our atmosphere stretches way out beyond the Moon's orbit!
What also makes this a very interesting story is that the discovery was made reviewing observations made TWO decades ago by a Sun observing spacecraft!
Apollo 16 astronauts Shepard and Mitchell photographed this region of the Earth's atmosphere called the Geocorona using the first telescope on the Moon. The picture was taken in ultraviolet light.
This really shows the power of going back over archived data to make new discoveries.
Pretty amazing.....
