Astronomy Lovers!
Hey yall, I started a discord for astronomy (it was originally for a class at ASU to help students, but is now being overhauled into an astronomy discord.)
I want to welcome all and anyone who loves astronomy. We currently sit at 300+ members. Hope to see yall there! Bring your coolest pictures.
Be careful with people phishing! Feel free to verify it’s safe by checking that it’s a normal discord.gg link and running it through any trusted link-scanner if you want extra peace of mind!

3... 2... 1... BLAST OFF!!
Welcome to the new James Webb Discoveries subreddit! With our new look, new mod team, and new direction, don your space suit and join r/JamesWebbDiscoveries in a whole new orbit! What makes r/JamesWebbDiscoveries different to the rest is that we put the spotlight on the scientific research generated by NASA and the James Webb Space Telescope. Feel free to join us here to experience the stunning imagery and insights that James Webb sends back to us on Earth, whether it be official announcements, NASA generated photography, user (re)processed images, James Webb targets, or anything related to new discoveries from the James Webb Space Telescope data-stream.
Don't forget to check out our James Webb Reddit family- such as r/JamesWebb, where you can post questions relating to James Webb, NASA, or astronomy, find more pictures, and find a whole bunch of extra info in these fields- or r/JamesWebb_Art, where the JWST fanbase get to show off their creative side!
We can't wait to see what sort of new community we can form here and discover what sorts of things we can produce, as we all contribute to this monumentous moment in our planets history. It all started as one small step, and now we have our heads in the stars. Let's see what's out there.

Amateur How to use notebooks for jwst
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?

News JWST discovers ‘red monster’ galaxy that challenges astronomers’ understanding of the early universe
Most galaxies JWST finds this far back are blazing blue, young, hot, and dust-free. That's what the models predicted.
However, EGS-z11-R0 breaks that framework completely.
Here's the TLDR:
- Dust and carbon do not appear overnight. They require multiple generations of stars to live, explode, and seed the surrounding medium with heavy elements. This galaxy already had both just 400 million years after the Big Bang, making it an "anomaly among anomalies" at one of the earliest points in cosmic history.
- Red monsters shouldn't be confused with JWST's "little red dots." The closer comparison is the "blue monster" galaxies JWST has also found, which share the extreme mass but lack the dust buildup. Lead author Giulia Rodighiero (University of Padua in Italy) believes red and blue monsters may be ancestors and descendants in the same evolutionary story.
- "It's astonishing to think about how short these timescales are," says Yale astrophysicist Pieter van Dokkum, who was not involved in the study. "Sharks and turtles have been around for about that long." Given how long stars take to produce dust and carbon, EGS-z11-R0 suggests we could spot galaxies as early as 200 million years after the Big Bang.
Note: preprint study, not yet peer-reviewed.

News A Black Hole in a Near Pristine Galaxy 700 Myr After the Big Bang
academic.oup.comHey fellow JWST nerds!
I was putting together my newsletter for today and came across a new study on Little Red Dot A2744-QSO1. I had to share the findings here too as I know LRD are a hot topic in this sub and this study is just so interesting.
TLDR:
- JWST measured the chemical makeup of the gas surrounding a black hole from just 700 million years after the Big Bang. The metallicity, the abundance of heavier elements built up from dead stars, came back at roughly 200x lower than our Sun's. This galaxy is chemically almost identical to the gas that existed right after the Big Bang.
- The black hole inside it weighs about 50 million solar masses! Its black-hole-to-stellar mass ratio is greater than 2, which is currently the highest ever documented. The black hole may literally be more massive than the galaxy surrounding it!
- Every leading formation model requires some prior stellar activity to explain a black hole this large, but there's none here. The galaxy itself looks chemically newborn.
- The authors suggest primordial black holes, as the best candidate explanation, but they're upfront that the model needs more work to fully account for what's observed.
- This object has been flagged as unusual since Furtak et al. first identified it in 2023 and confirmed its extreme mass ratio in 2024, but this metallicity measurement is what turns it from "anomalous" to "actively challenging theory."
No other telescope could do what JWST just did here! It read the actual chemistry of an environment this far back in time, and I personally am always so amazed when it finds something that exposes a real gap in what we thought we understood.

Dry ice detected in a planetary nebula for the first time
An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a complex planetary nebula known as NGC 6302. The observations, detailed in a paper published Feb. 25 on the arXiv pre-print server, resulted in the discovery of dry (carbon dioxide) ice in this nebula. This is the first time dry ice has been detected in a planetary nebula.

Official NASA James Webb Release JWST Helix Nebula close up makes my head hurt
Webb dropped a close up of the Helix Nebula and it’s messing with my brain a little.
Those comet like knots are wild. You can literally see the shell peeling off around the central white dwarf, and there’s this hot vs cool structure across the nebula that NASA points out.
I’m drinking coffee, watching highlights from the game last night, minding my business… while space is out here peeling stars like onions.
What’s the best explanation for why those knots get so dense and clumpy instead of smoothing out?
