The JWST is just 16 mirrors that produce one image of what is looked at, incl. planet Venus.

Heiwa is dactylly challenged and only has 4 digits on each hand and foot. That's why he can't count to 18.

Oh, yeah. He's also missing his dick.

Technically, its 3 mirrors with the primary mirror being made up of 18 segments.
What Kind of Telescope Is Webb?

Webb is what is known as a three mirror anastigmat telescope. In this configuration, the primary mirror is concave, the secondary is convex, and it works slightly off-axis. The tertiary removes the resulting astigmatism and also flattens the focal plane. This also allows for a wider field of view.

Each of those segments is a mirror. So I guess it's a 20-mirror telescope, and 18 of them just Megazord themselves.

Anyway the JWST mirrors reflect IR-light from the end of the Universe billions of light years away, when they are adjusted, and one day we will see a color picture of it. And then all is clear and explained.
It would have been easier to put the JWST on the Moon with its clear weather every day, but maybe it was too close to Earth then? No, L2 is the perfect location. ROTFL.

Why would anyone in their right mind put an infrared telescope on the moon where it would receive daylight for 2 weeks at a time?  Despite the name of the Pink Floyd album, there is no dark side of the moon.

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.

Yep. If I want to cool my beer to -370F when the overhead sun is making my mug and all the surrounding landscape >200F, then I “just put a parasol” over it as protection.

Good thing those tanker designs don’t count on you for any thermal analysis.

No, the parasol stops the telescope from heating up by direct sun radiation. Ok, heat of the Sun is also reflected from the surface of the moon, so you have to consider that too.

So you’ve just answered one aspect as to why put JWST at L2. The Moon is not an appropriate thermal environment. Neither is Earth orbit. L2 is.

Not really. If L2 is really in the shadow of Earth/Moon, it very cold there with no need for a heat shield. Solar panels are useless at L2. But you'll no doubt say that JWST orbits L2! As soon it is exposed to the Sun, a parasol is enough protection as long as you look in the other direction. Never look at the Sun, when flying in space. Your eye will melt. I know that the asstronuts had sun glasses on the Moon, even if they were hard to fit with the gloves used.

You're beginning to have the basics of comprehension, but you don't remember what you said previously. Or what others have said previously.

By "at L2" yes I meant orbiting it so that solar panels will work. Yes, a parasol works there because in the other direction is 4 degree Kelvin space that heat can be radiated to and from which no incoming heat load exists. That is not the case in your example of JWST lounging under a parasol on the surface of the Moon. Or in orbit around the Moon. Or in orbit around the Earth.

Hopefully you've learned just a little bit more today and won't be such a doofus in future. We can hope.

No, it's not.  It specifically avoids Earth's shadow to avoid thermal stress due changes in temperature.  You have been told this before.

Heiwa is playing pedantic games. L2 is in Earth's shadow; JWST (and other spacecraft) trace a halo orbit around L2 and are not in Earth's shadow.

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?

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.

Yes, you would see infrared light equally as well with your eyes looking from space as you would using them on Earth, but that's why this telescope can see different wavelengths than you can. It has better eyesight than you ever had in the visible AND infrared part if the spectrum, and a more isolated location to collect all those delicious photons.

I am sorry that I cannot go to L2 and from there watch the end and beginning of the Universe in IR using a telescope. Actually nothing can fly to L2 and watch anything from there. The JWST and it's handlers are a fraud and cannot explain anything of it.

That's OK. As luck would have it, there's a piece of equipment that can see better than you could even in your younger days that recently arrived in that vicinity. All you have to do is sit back and wait for the images to start rolling in, then you can use your eyes to see the images it was able to capture. I'm sure they'll all be shared on a very popular website that gets many visitors.

I agree. Imagine! Pictures of the end and beginning of the Universe. In IR! Taken orbiting L2.

How can Earth be at the center of the Universe if the Universe is infinite with no end therefore there is no center?
