It doesn't refute anything. The point is rather; what matters to you is part of your personal journey. Ultimately it still doesn't matter in the grander scheme, but that isn't the point of enjoying your adventure while you're around. Does the cosmos care if I give my Mother a birthday present or not? Unlikely it does. Do I? Yes, I send one every year. Does it matter then? Not really, but I like doing it because I lik…

I think we nearly agree, but I’d say you’re throwing the baby out with the bathwater. The bathwater is the notion of a subjective cosmos, some overarching supreme being to whom specific events ought to matter somehow. I’m very happy to throw out that bathwater, along with other theocratic sophistries that still influence our thinking too much. The baby is meaning itself, all of which takes place within the cosmos, an…

"to matter" means "to be of importance".

And to me, sure, those things matter. But I also acknowledge that this isn't an objective thing the cosmos put into the world but a personal feeling. My argument is essentially that you've got to do that. Acknowledge that what matters to you is something personal. And to cherish that because the journey is important. I see it as a pathway to positive nihilism.

I'm convinced we are receiving "Wobbly Photons" Meaning that no matter waht, when we speak of gravitational lenses, we could, usting JWST account for the "wobble" of a photon, nased on the accurate knowledge of where a body was, via measuring through multiples of JSWT observations... (ideally through actually multiple JWSTs, in differnt locations) The idea being that if we can triangulate a more precice location betw…

We already calculated the gravity and mapped it out. Here is a paper on some of the research: https://www.kiss.caltech.edu/papers/darkmatter/papers/the_da... What i think is pretty cool is that the gravity lens actually allowed hubble to see galaxies it may have not ever seen had there not been a gravity lens and now that we have JWST we see many more distant galaxies (and more of the same galaxy reflected in more po…

Why have we not seen results of these scopes pointing at near bodies?

What does jupiter, PLUTO look like from these lenses???

THE FUCKING MOON

WE SPENT *BILLIONS* -- Why dont we have live streams?

GO FUCK YOUR NSA

WHO PAID FOR IT.

The data should be global. define a SINGLE national defense trope. and back it up.

Thanks! I worded that poorly ; Wouldn't one be able to adjust the perceived path of the photon after time, to adjust for re-normalizing the path of the photon based on the understanding of the gravitational arc imposed on such -- meaning the astro equivalent of "ZOOM. ENHANCE!" :-)

Ah right, good question yes it seems like it could be possible..

The normalization I was thinking of was :

Lets assume you have a 'straight' vector of line of sight pointing your Earthly-Bound-Lens [hubble/jswt/whatever] at the object of interest.

you also have an idea through previous observations of gallaxies on the line of sight, which will have gravitational impact on the trajectory of the photons of interest...

the arrival photon's wiggle represents a wobble in time to get to earth. Meaning it changed phase multiple times between our sensor receiving it, and its origin.

If one could look at the path and the grav-lenses it went through, one may be able to extrapolate a more clear picture at various distances(times)....??? /r/NoStupidQuestions

( I am picturing a straight shot - but the photon traveled between many other celstials - and those

These are Webb's first science images, so published papers will come out of them. Of course, those papers will have additional data and analysis to go alongside it, but they absolutely are looking at details resolved in these specific images, processed in this specific way. So I'm not sure where the sentiment that these are just images for the public is coming from. That's certainly part of why these observations wer…

"but they absolutely are looking at details resolved in these specific images, processed in this specific way." I don't think you're correct. PR images from telescopes aren't new, so if you are correct then surely you'll be able to find papers based on older photoshopped images from Hubble. Are you able to find any?

There are countless examples. The reason they composite the sensor layers in the first place is because they are trying to color code gases and dust for use by scientists. In some cases they are trying to highlight features that would be too dim otherwise.

Here is an example of color-coded images from Hubble being used - https://iopscience.iop.org/article/10.1086/345911/pdf - The same beautiful image used to get the public excited about space is used in Fig2 to locate where helium, nitrogen, and oxygen are in a planetary nebula. Even the 'Pillars of Creation' image was used for this sort of analysis, though it was less interesting than most images.

"Beautiful" just happens to overlap with "highest contrast and most useful for study". JWST has more sensors than ever before, so it will be more colorful than ever before.

Thanks, but how is the sausage made then? Guess, that’s my main question. I get that the aquired data needs to be transformed in a way so we get an image that depicts a reality we can visually process. I honestly thought there’s some tools in Nasa’s imaging group that, based on scientific rules, pumps out an image that is correct - seeing Photoshop in use left me wonder… I get that the investment needs to be “sold” t…

Photoshop is literally just a matrix transformation engine for data that is highly optimized for ease of use, extensibility, and making visual representations of that data.

Would be awesome to see if anyone can do machine learning using photoshop

I know nothing about optics. What is the effect that causes the 6 or 8 points of light of come off of bright objects? Does it have to do with the hex-shaped mirrors on JWT?

The simple answer is simply because of the physics of the scope, the support arms cause diffraction spikes. The hubble has them too but is a smaller mirror and different support arrangement. Super common on consumer scopes such as RCs, Newts and big tube scopes that aren't RASAs

> “Cosmic Cliffs” in the Carina Nebula (NIRCam Image): > https://stsci-opo.org/STScI-01G7ETPF7DVBJAC42JR5N6EQRH.png Is this for real?! It looks like it came right out of a Sci-Fi movie/book. Could anyone explain how much of this is post-editing magic?

I'm waiting for https://en.wikipedia.org/wiki/Pillars_of_Creation made by Webb. It's not the same object, but similarly awesome. Maybe the article gives you an useful overview of how different telescopes 'see', and how that is translated into pictures for us.

The difference between 'actual science' and 'some touched up version of objects in our universe' is smaller than you might think: no matter how good your eyes, if there was no frequency shift involved you would not be able to perceive the image, other than as an array of numbers. To facilitate your consumption of the data it has to be frequency shifted and the easiest way to do this is to map the IR intensity to a ra…
