Hello Avalonians & Avalonettes what do you think of this new assertion? & How will it change our understanding of our solar system?

The Moon Lies Within Earth's Atmosphere Claims Study

Published 24th February 2019



Our planet's atmosphere (the hydrogen geocorona) is much larger than first thought, extending far beyond the moon according to a new study by scientists.

Well, that's going to be so totally misunderstood by a whole bunch of silly YouTubers that we can now expect a slew of grossly misleading videos about it. And John Lear might have a field day.

Of course, we're talking about a VERY VERY VERY VERY thin scattering of hydrogen molecules, but there's something just a little tiny bit there.

It's really all about the definition of a vacuum. The rest is journalistic hype with headlines written by editors with no knowledge of science.

In fact, a little more. The RT article is a bit sensational (hence my 'editors' comment ^^ ), but the best popular articles (as one might expect) are from the ESA and NASA. They both contain the same text.

• https://sohowww.nascom.nasa.gov/hotshot/index.html

This paragraph in both articles explains the numbers:

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.

So way out at the moon, that's 1 hydrogen atom in every 5 cubic centimeters. Not quite an interstellar vacuum. But hardly an 'atmosphere' in the way most people would understand the word.

Thanks Bill,

looking forward I wonder what that will mean for terraforming/geoengineering...

Nothing at all. 1 hydrogen atom in every 5 cubic centimeters is a vacuum for all practical purposes!

I seem to think this observation came out years ago?
Hmm!

This is what click bait journalism gets you, eh?
