As L has no mass you cannot orbit around L.

That statement means that you are either talking crap now, or you were lying when you said this:

But I know what a barycenter is.

In a two body system where both bodies are of similar mass, both bodies will orbit a point that has no mass itself - the barycentre of the system.

You contradict yourself, again.

Why the JWST has to lift of from Earth to fly to L2 is beyond my understanding.
Yes, quite obviously.  There are a few good reasons why L2 is a handy place to hang out.  Among other things, it requires little energy to maintain its orbit around L2.  Being a million miles further from the sun than the earth also means that it has a larger baseline for doing parallax measurements of distant stars.  JWST's orbit also far enough from the the sun, earth and moon so that the sun shield can keep the infrared instruments very cold without the need for cryogenic coolants.  The orbit around L2 also keeps JWST out of the earth's and moon's shadows so its thermally stable, which is a good thing for infrared astronomy.

Please explain what orbits what!
Quite simple.  Sun-earth Lagrange points orbit the sun.  Earth-moon Lagrange points orbit the earth.  JWST orbits a sun-earth Lagrange point commonly referred to as L2.

No, JWST took off from Earth and still orbits Earth all the time in a very elongated, variable speed/direction orbit in a certain plane around Earth that I doubt intercept any orbit of L2 around the Sun. Problem is to change the JWST orbit at L2 and dock with L2. It is very difficult as L2 moves all the time in another plane around the Sun. I think you don't know what you are talking about ... like ESA/NASA.

You keep talking about JWST docking with L2 and you think that I don't know what I'm talking about?  ROTFL

Why don't you explain to us, in detail, how and why it's so very difficult. Just stating it's difficult is like me saying, "It's very difficult to climb Mt. Everest."

Regardless, I really look forward to the pictures of the Universe taken by the JWST at L2 after all adjustments have been made. Experts will probably say the pictures are fantastic and of great values to explain something ... that I don't understand. Haven't I heard that before.

Perhaps it would help if you were to open yourself to the possibility that there is more to astronomy than just looking at the night sky from your window.

I like looking myself to verify things I am told are happening. Just because a rocket takes off doesn't mean that it arrives at L2 after a month, etc, etc, bla, bla, bla.

Take a picture of Venus from your window and show us how clear it is.

Btw, here's what it looks like from your window right now. Looks kinda blurry to me.

It is pretty cloudy right now. The Nice telescope 18 km west cannot see anything too. Anyway, JWST can only see away from the Sun protected by its Sun shield behind the mirror. JWST must be kept in the ice+ cold shade of its shield to function properly. If JWST by mistake looks at the Sun, it will melt and become useless. As Venus is between JWST and the Sun, JWST cannot observe Venus, as I do from my window.
So JWST will capture the infrared light of the early Universe seeping in from far away, we are told. I really wonder what it looks like. I cannot see it, as infrared is filtered off by the atmosphere outside my window.

And again, here we can see the result of Heiwa asking himself a question on the internet ("I wonder what a JWST picture of planet Venus will look like from L2"), googling to find an answer, and then posting that answer in a follow-up post as if he actually understood what he read. It's truly a marvel!

Yes, they have been saying that it would take a few months to adjust and calibrate the mirrors to give clear images.

Seeing as Venus is a hot planet near an even hotter sun and JWST is an infrared telescope, I would think that the pictures would be completely blank because the infrared sensors burned out.

Thanks for comments. The JWST is just 16 mirrors that produce one image of what is looked at, incl. planet Venus. It will not melt then. Only looking at the Sun isn't possible. I on the other hand can see the visible universe by looking out of my window in clear weather. No adjustments required. But let's face it - the JWST is a hoax.

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

You sound like a loser with your foul language. There is no JWST at L2! It is a hoax!

Provide one piece of evidence whose source is not you to support this claim.

I didn't say that it would melt the mirrors.  I said that it would probably burn out the very sensitive infrared sensors.

I on the other hand can see the visible universe by looking out of my window in clear weather.
Good for you.  JWST will be able to see far more of the universe that is not visible from your window.

No adjustments required. But let's face it - the JWST is a hoax.
If that's how you feel about it, then every telescope that can see beyond the visible spectrum, terrestrial or space based, must also be a hoax.  I suppose x-ray, radio and infrared astronomy must all be fake as well.

Is it, now? Fascinating. Your knack for engineering and keen attention to detail never cease to amaze!
