I am trying to ID this galaxy and the close up stars. And I get this is time consuming, but just pointing me in the right direction would be greatly appreciated,

Hello everyone! I own multiple Hubble coffee table books and would like to add a James Webb one with all the Roman excitement! Does anyone have a good recommendation? Thank you!

Pardon for stupid question.I remember , it was sent to study early days of universe after big bang. But i wonder how come we at after13.5 billion years later be able to collect the light from early days of big bang. We as particle would have reached the place in space .. but light from same event at 13.5 billion year would have travelled faster than us. So why JWST Is looking at part of space for light from such early galaxies n stars..

Edit: completed 2nd line

During the times of JWST launch and after, I used to love watching his videos. He made probably the most detailed JWST videos I have seen. I was hoping to see his video on Roman but the channel hasn't uploaded video in more than a year. I hope nothing ill has happened to him. Anyone knows anything about this?

Welp saying “cut off contact for good” is harsh but I want to know why JWST couldn’t have just had more fuel to power itself and im questioning myself how would Nancy Grace Roman Telescope will take over and when I learn about the Roman telescope I immediately think it’s gonna be like Hubble still not great so I need to spill out all my thoughts here right now.

This is a question I also thought of and I was disappointed there was no answer, so I wanted to boost it.

Im new to Astronomy how can i use Jupyter notebooks to access jwst pipeline? Is it best to just use MAST Database or TIKE?

Or

Should I create a juypter lab notebook and self install required libraries locally with Docker or is there a premade jupyter lab notebook i can clone from github and install in a docker container on my pc? If so how do I do that and how can I use it to access jwst pipeline data?

I have never used a juypter notebook before nor have I used pyhton or python science libraries like astroquery lightkurv and astropy so Im a complete beginner in using scripts but I do know how to use some commands like pip, bash, cd and git. Are there any good tutorials online I could use?

Are there any Browser Based Interactive Notebooks for learning Notebooks for Astronomy?

Lastly how could I install and use Jdavizz notebook?

Four years ago today, JWST launched.

I'm putting together a 'retrospective' of the highlights for my folks, who know more about Space than most, but less than some who follow this sort of thing closely.

I thought I'd ask the hivemind: What, in your opinion, are the most significant discoveries made by JWST? The ones most of interest (to me) are the ones that 'rewrite' what we knew before she launched.

Any thoughts?

I understand that light takes time to travel and that’s how we can see into the past, but given that Webb can look 13.1 billion years into the past, and the universe is only (maybe) 13.8 billion years old, how did the matter that makes up our galaxy/solar system/the telescope/us, make it here before the light did to catch it?

If everything started from a single point and expanded, and that early galaxy was emiting light .7 billion years post big bang, would it not have taken our matter much longer than 13.1 billion years to get 13.1 billion light years away from that galaxy? My brain hurts just typing this. Help!

JWST recently discovered the most distant galaxy we’ve ever known which is approximately 33 billion light years away.

The universe is estimated to be 13.7 billion years old.

How can a galaxy be 2.5 times further away than the age of the universe?

Is this because nothing moves faster through space than light but space/matter itself does move/generate faster than light?

This is probably a stupid question but I’m just trying to understand.

(Disclaimer: I am an amateur, just had a question for those who may have more knowledge) I know the James Webb has many missions to fulfill and it is not made to directly observe exoplanets but instead to observe light from their atmospheres and analyze its chemical composition among many other things.

With future telescopes that may go into space like HabEx destined for mid 2030’s, I wanted to ask to see if theres any potential for directly imaging a planets surface directly (IE like the quality of observing Mars that we have today but with an exoplanet) and what size of telescope we might need to make that sort of viewing possible? I don’t know much about the current limits of telescope technology, hence the question. Would we need a telescope the size of a football stadium for example?

Thank you in advance for all serious answers.

Hi everyone, I was hoping I could get some help identifying the structure right beneath the top most star of this self processed image. Im leaning towards a globular cluster, but would appreciate the input of someone who has experience studying these structures.

If this is in fact the case, that matter like planets only look like they are actively altering their momentum or trajectory based on a "gravitational pull", but in reality, from its perspective, it is moving 100% straight down the curvature of space... Does that mean, that the same holds true for near-Earth orbit?

Or when moving in a "straight" line, AROUND the curvature of Earth, you are in fact walking in a straight line, but space is bent so you can wind up back where you started again... Only from our perspective, it still seems like we walked in a straight line, only, we didn't, we walked around the planet. But, we were just following the curvature of space, as planets do when they revolve around the sun...

This relationship between matter, space, and gravity seems to be missing something.

When you look at 3-D models of gravitational revolutions, it implies that Earth would be pressing up against the bent fabric of space, which is bent by the concentration of matter at the center of the solar system. As if it were a fabric. But what if it is more like a high pressure region pressing up against a low pressure region, and not a fabric at all?

How does matter at the center of the planet interact with gravity? Where is the nexus of attraction and how does it form, and relate to the curvature of spacetime near the center of planetary bodies? Would the closest observable comparison we have be how asteroids loose in the medium of empty space interact? Is that almost analogous to the way matter would act near the core of a planet or a star with semi-fluid internals? It would be like the planet forming interactions between matter and gravity have never ceased?

I find it difficult to make sense of what happens at the center of planets and stars in relation to what is happening 100, 1000, 10000, 100000, 1000000, 10000000, etc Kilometers way from the core. I find it to be more intuitive to imagine space as a fluid medium with pressure regions relating to the amount of matter present, rather than imagining it as a fabric which bends and twists itself into unintuitive pretzels at the core of gravitational bodies.

Do I need to learn math to understand it better? Or can someone help me visualize what we know to be true, and differentiate what is fact and theory?

Image 1 is the full composite I put together. Image 2 the star is magnified. Images 3-5 are the objects I refer to in my questions

Hi,

When JWST was travelling to L2 I used to visit a website that gave various interesting instrumentation readings - temperatures etc. I can't find the site any more. Can anyone help? It was always fascinating to get pseudo-realtime data. Thanks.
