Hm, the Sun shines on the Moon all the time (except if Earth is in the way) and the universe around it. It is a perfect place to study the universe because there is no atmosphere filtering the light. If you are afraid of sun heat radiation, you just put a parasol/heat shield above the JWST as protection. And if you are afraid of the coldness, you fit a heater. I cannot understand why ESA/NASA chose L2 as viewing point. The Moon is much better ... if you can get there without crashing when landing.
You have no idea of the conditions required for infrared astronomy, do you?
BTW, doesn't one of your "challenges" say that it's impossible to land on the moon?
If L2 is really in the shadow of Earth/Moon,
It's not.
It is.
The L2 point is in earth's shadow. JWST's orbit around L2 is not.
Thanks for questions and comments.
No, infrared astronomy is same as visible light astronomy, as far as I see from my window, even if my eyes cannot see IR light. I don't expect that the secrets of the Universe are in the IR range. Or anywhere. The Universe is infinite with no end.
Yes, landing on the Moon will result in a crash and is not a way to visit the Moon. Nobody has won my funny €1M Challenge about it. Nobody has ever landed on the Moon and survived. But plenty fools say they have done it.
L2 is just a point in the Universe in the shadow of planet Earth. You cannot orbit around such a shady point. But plenty fools say they do it right now in the heat of the Sun and are adjusting a telescope to watch the Universe in IR color. I think it is hilarious ... and a fraud/hoax.
