What the hell are you talking about? We've already gotten plenty of public pictures of JWST in the ONE year it's been in space, plenty of which has been spent calibrating.

This article is just a beautiful picture by Hubble, which is still doing a great job.

Reply to comment by websterhamster in ‘We found the Artemis-I noise level at 5 km had a crackling quality about 40 million times greater than a bowl of Rice Krispies.’ — Maximum noise measured during Artemis-I launch on 16 Nov. 2022 was higher than predicted by marketrent

So if you're at postion, and you change position, we call that velocity. If you change between two velocities we call that acceleration. If you learned this in school you would call these derivatives. Well when you take the derivative of acceleration, you get something called jerk. And the derivative of jerk is called jounce.

But jounce is a horrible name, so they started calling it "snap". Naturally this lead to the next two derivatives being called "crackle" and "pop".

These aren't the official names, but they don't have official names so "position, velocity, acceleration, jerk, snap, crackle, pop" is officially unofficial

>When two galaxies come close to each other...

I thought this was going to be The Talk about when the Mommy galaxy and the Daddy galaxy give each other a very special hug. Was disappoint.

THAT SAID, when galaxies collide, how does it effect what's happening on a any given planet or solar system in the colliding galaxies? Because for the most part everything just zips right past everything else, right? There's very little matter actually colliding

Until you're reminded of the fact that your planet might never rejoin the galaxy which keeps pushing further away from the stranded tail.
