Astronomy James Webb Space Telescope

It is not false color per se, they are just adjusted to the visible spectrum, or we'd be looking at nothing.

The JWST uses reference data from it's different cams that work in different infrared spectrums
here an easy illustration
instrumentranges.jpg


what they do to make these pictures contain any data for us is move it from the infrared spectrum to the visible spectrum,
but keep the dimensions the same, making the data usuable.

The picture you're looking at is a composite image from two cams NIRcam(near infrared) and MIRIcam (mid infrared), first of all
Revealing_details_of_the_Cartwheel_Galaxy_pillars.jpg


what you're looking at is a galaxy which has been rammed right in its center, several hundred million years ago, by a smaller galaxy,
and in reaction has formed this outer ring, which has turned into a birthing chamber powerhouse for stars,
it's the remnant of the smaller galaxy which has been absolutely obliterated by the larger one, and created this violent outburst of star-birth
it's super nova upon super nova making more and more stars, as star death, if the star was big enough = star birth

before the collision it must have looked very similar to Andromeda or the Milky way.
In the center you can see the dust is much more evenly distributed, speaking for the fact that it's much older than the outer ring that has formed after the collision,
and of course for the fact that there are much older stars inside the inner ring, among newer ones, while the outer ring should almost entirely be baby stars and super novas.

The reason why it looks so stylish is the freakish amount of hot dust twirling inside, which ofc was also created by the collision,
and the subsequent collision of at least several billion stars.

Pretty cool, huh?

edit: there are dozens and dozens upon publications about JWST findings,
I listen to them all day at work(well.."vacation" from my first job for 16 hour work-days..), presented by my favourite astrophysics professor (sadly a German, sorry)

but in English there are even more publications, so it would be easy to find something

edit no 2: the whole thing isn't too rare, although they were once considered the rarest galaxies in the universe.
Ring galaxies like this one have been found often by Hubble, like this beauty, which actually has two

Carrying the beautiful name NGC 1512

or Hoags object found in the 50s

Galaxies collide or should I say collided all the time in the spacetime we can observe.
It's one of the not too many scenarios of how new stars can form.
Second to last pic look eerily like an eye
 
You’re incredible wrong.

If it weren’t in orbit, it would be on its way out of the solar system.

"You're incredibly wrong.", I said, having no idea what he was talking about whatsoever...
but I knew he was wrong, since my mind wasn't able to process the information

humans :rolleyes:

don't tell me i'm wrong if you're not even ready to do a scintilla of research.
nobody in the scientific community needs your opinion if that's how you do science,
by guesses and off-the-cuff arguments, and stuff. especially incredibly wrong?! screw you, no offense

rofl, even if it left Earth's orbit without the ability to maneuver to its own orbit around the sun,
it would still start orbitting the sun, not leave our solar system, cuz that only works with enough momentum, like they did for the voyagers,
and you need a fucking shitload of momentum for that

if you were to try and shoot a rocket in the opposite direction of earth's orbit around the sun at the same speed the earth is orbiting the sun, and reached 0 velocity relative to the sun, it would still either crash into the sun, or depending on earth's gravitational influence, start orbiting the sun and eventually "fall in"

also nobody cares if stuff drifts out of the solar system, voyager 1 is 160 AU away from the sun, 160 times our distance to the sun.
to put this in relation, our solar system is about 80 AU in diameter, so 39 AU is enough to leave it,
still sends data, just takes longer to receive, 22.13 hours if you wanna do the math. does anyone care? absolutely not in the fucking slightest

space is so empty that data just travels through it unchecked (see distant galaxies)

if anyone is interested, here JWST's spectroscopy data of the gas composition around an active black hole in this recording

especially the outflow of ionized gases is super interesting, underlining once again(this time with permanent marker) what a crucial role black holes play for their galaxies, and how ridiculous the idea is that we're the only (intelligent) life out there

black hole farts in detail
i absolutely love this telescope 💘
 
Means it’s in orbit around the sun.

If it weren’t in some sort of orbit it would be flying out of the solar system.
Uh, yeah what i said is it's not a satellite because it's not orbitting a planet. Satellites orbit planets duh, that's their whole deal.

What you said was that if it's not orbitting earth it will just plop out of the solar system, which is wrong on every level, even if you want to talk semantics about what's a satellite and what isn't. Forgetting about sun's gravity means you didnt pay that much attention in astronomy 101

However the definition of satellites is that they orbit planets, one could argue how planets are satellites of the sun, that wasn't my point
my point was that it's most certainly not earth's satellite as you suggested, and neither do things fall out of the solar system if they're not attached to earth (can't believe i have to spell this out :rolleyes:)

And before you try to counter this
not a satellite because not orbiting earth,
the word comes from Latin and means "follower" or "attendant"

I never said it wasn't orbiting anything,
just not earth

If I took you by the word, which I did, because it's kind of my thing, I would have to assume that it's your understanding that things not orbiting earth fall out of the solar system, which ofc, sounds incredibly wrong.

How you came to read into me stating that it's not orbiting earth meaning it's not orbiting anything (which is ridiculously hard in space) I will likely never understand, so will just write it off as a brain fart.

Except you’re still wrong. I even used Bing.


Says it right there. It’s a satellite.

I even got a warning for that reply.

I already argued that the word could be construed to an object orbiting a star, since it just means "follower", but then that would make planets satellites too, in fact that would make the solar system itself a satellite of the milky way, and you could just go on calling everything a satellite, if that helps you navigate the sky.

One might note that you used Bing, because Google uses the Oxford definition of the word, which does not include stars, and the NASA definition does include stars. As I said, semantics, shut the fuck up about them already

What you cannot argue about is that I said "it doesn't orbit earth", and you said "but then it would drift out of the solar system", entirely forgetting that the sun has a much higher gravitational force than earth.

Anyhow i'm done with you, good bye

Yes, and that’s why I have no friends.

Use up and tell me to fuck off

:rolleyes: maybe don't tell people they're incredibly wrong when they just want to explain stuff to you

I like explaining stuff, but when my explanations meet someone who doesn't give a fuck about the subject and is one of those "hey let's call everything a satellite so it's easier what to call stuff, our home satellite has a natural satellite and 200 manmade satellites and is itself a satellite to a bigger satellite that is a satellite to a bigger satellite which might also be a satellite to an even bigger satellite" people, im going to lose my patience and yes, would prefer if you fucked off 👍

These pictures give me the same emotions I'd imagine religious people experience when they witness a miracle.

Both a deep sense of awe and a bewildering feeling of the unimaginable mystery of the universe.
I find the idea that we've been spinning around the sun at thousands of miles a hour terrifying. Black holes that move!! Ahhh what! Also I think the entire world should get together to start working on bringing a astroid back to mine. I mean if we could pick the perfect one we could stop harvesting minerals from are earth .. right? My friend thinks there no way to do it but couldn't we just smack them into the moon and mine them... I think China is going to try and aim one at us eventually. Hope the James Webb is watching for that! But I do find space to be amazing I just think it's all to perfect and it doesn't add up to me why were so small and stupid and space is so mighty and vast. I wish we could find live else where.. it's just confusing why we live so short of lives..
