Okay, whose idea was it to make the COSMOS field so big?!
Every time I go through the catalog, my tiny brain is convinced I've done something wrong because there are just SO MANY GALAXIES 🤯😱🤩

NEW PAPER: I have discovered that up to half of all black holes that shred a star "burp" material years after the initial event and turn on in radio!!! No one was expecting this, and we don't really understand why this might be! 🤩🔭🧪

This is so COOL!!

Appropriate that this overview of JWST's first year of science by Joel Achenbach ends with me crying over galaxies 🔭🧪

NASA is marking the first anniversary of the James Webb Space Telescope’s scientific debut with the release of a new image, demonstrating the telescope’s ability to re-envision the universe.

Here’s Joel Achenbach for the Washington Post on JWST’s first year with nice quotes from @janerigby.bsky.social, @jeyhan.bsky.social, @saturnswings.bsky.social and many more! https://www.washingtonpost.com/science/2023/07/12/jwst-new-picture-first-year/

Second galaxy to the right and straight on until cosmic dawn! This video takes you on a journey through our CEERS JWST images and cosmic history. Every second we travel 200 Million lightyears into the past on our way to Maisie's Galaxy which existed ~13.4 Billion years ago!

Can I start the fight over which emoji we use?! For no biased reasons we should use this one: 🪐

And, of course, I wouldn't be me if I didn't shout about just HOW MANY GALAXIES THERE ARE in our newly-released FULL CEERS field image!! Download the high-resolution image (NOT on your phone) and get lost in space with us!

And it's not just black holes we've been finding in our CEERS JWST spectra, but we're also able to measure the distances to galaxies first discovered in our JWST NIRCam images. The papers, led by Seiji Fujimoto and Pablo Arabal Haro, are seeing even further back!

The press release also highlights two other AGNs (active black holes) identified in Dale Kocevski's paper. These two are smaller and not the dominant source of light we detect, speaking to the power of JWST's resolution.

Why is this so interesting? Well, it's the first (of many to come, I hope!) black hole we've detected so early in the Universe. This is possible due to JWST's wavelength coverage (it can see further objects) and sensitivity (it can see fainter ones too)!

Here's a highlight about the black hole, CEERS 1019 that shows the emission from both the host galaxy (purple) and the black hole (yellow) in our CEERS JWST NIRSpec data. Plus, an image from NIRCam where you can make out the multiple physical components!

😎 Love that you centered the image on it! 😁
More info here too 🧪

We found the most distant (to-date) active black hole at the center of a galaxy ~570 Myrs after the Big Bang (>13.2B yrs ago)!! 🧪

Now with an official press release and fancy graphics from the fine people at Space Telescope Science Institute and NASA 😍

First post! Let's kick things off with our #JWST NASA press release today on high redshift galaxies in the CEERS Survey, and highlighting work from @saturnswings.bsky.social
