Before you see a Webb image released by NASA, the data stop at STScI—home of Webb’s Mission Operations Center. Tomorrow, on the anniversary of the start of Webb’s science operations, we’ll release a new image that you won’t want to miss! Credit: D. Kirshenblat (STScI).

Fly to Maisie's Galaxy in this 3D visualization of a small portion of the CEERS (Cosmic Evolution Early Release Science) Survey from #JWST.

We travel about 200 million light-years into the data set each second and see 200 million years further into the past.

The video ends at a galaxy, named in honor of the Principal Investigator's daughter, which we see as it was 390 million years after the Big Bang, or about 13.4 billion years ago.

A video that displays thousands of galaxies. The video begins with an image of several thousand galaxies. The words “Cosmic Evolution Early Release Science” are overlaid on the image before the words are reduced to their initials, C E E R S, and a second set of words appear next to it that say “Flight to Maisie’s Galaxy.” These labels disappear and the video begins, zooming in and moving the field of view toward the right for several seconds to reveal even more galaxies shaped like fuzzy ovals and streaks. The video then pans left for several seconds, revealing galaxies of different shapes that are mostly yellow and red. As the video moves to the right again, there is a noticeably lower distribution of galaxies. These galaxies are also fuzzier with less defined shapes. Lastly, the video zooms into the center, revealing a single, fuzzy red galaxy, Maisie’s Galaxy. The video ends with labels for the credits, which are listed lower in the caption.

Ever wonder how #JWST images go from raw telescope data to the beautiful press release images you on social media?

Check out this video series from @spacetelescope. I was on the team that put these together.

In this first video, we show you what the raw data looks like and how you can download it yourself.

Learn more about the process here: https://webbtelescope.org/contents/articles/how-are-webbs-full-color-images-made

How does this [image: black screen with a few dots] become this [image: JWST pillars of creation]? Joseph and Alyssa stand in front of the Mission Operations Center for JWST at STScI.

As a science communicator, I was interested to explore #threads.

So far, it feels like everyone is shouting everything all at once with no organization or order. There are no hashtags to help discover topics, for example. I mainly see a lot of celebs & influencers I don’t follow.

I’m not sure it can become a place to exchange meaningful ideas. But that’s probably not the point.

I’m happy at #Mastodon & there really is no comparison. It will be interesting to see how it all evolves over time.

Went on a tour of the NASA Goddard Space Flight Center with a group of students today. It was fun!

We got to see parts from the Nancy Grace Roman Space Telescope being tested in the clean room.

Equipment sits in the NASA Goddard clean room, a large, 4-story white room. In the room are several metal tables, testing equipment, and parts of the telescope bus. In the back corner is a large hexagon-shaped ring with panels coming out of it. This will form part of the telescope. On the right wall are rows of orange squares, which are a wall of air filters

This galaxy CEERS 1019, which looks like three blobs, houses the most distant active supermassive black hole found to date.

We see signs of the black hole in the galaxy's spectrum from #JWST. The yellow model fits gas swirling in the black hole’s accretion disk. The purple model with a high peak fits slower gas in the galaxy.

Let's take a peek into the Orion Bar, a portion of the star-forming Orion Nebula, with #JWST.

Just out of frame are the young, massive stars of the Trapezium Cluster, which shine brightly in energetic, ultraviolet light. Light from these stars interacts with the cold, dense, dusty gas of the Orion Bar.

The pullout at the bottom right shows a young star system with a planet-forming disk, which is being blasted with ultraviolet light, causing its extended shape.

Hello new users, or folks coming back for a second try! If you are turned off by the UI, and you don’t mind paying for an app, give @Ivory or one of the other 3rd Parth clients a try. They make a world of difference.

New image of Saturn, as seen by #JWST.

This image was taken through a single filter (at 3.23 microns), so we are seeing a greyscale image that has been tinted orange.

The planet appears extremely dark in this infrared filter since methane gas absorbs almost all of the sunlight that hits the atmosphere. However, the icy rings stay relatively bright. We also see the moons Dione, Enceladus, and Tethys.

Check out this new visualization from Universe of Learning — Stephan's Quintet: A Multi-wavelength Exploration.

Based on data from Hubble, Spitzer, Chandra, and JWST, take a 3D journey through the galaxies in Stephan's Quintet. See the stretched-out features from the gravitational interactions between the galaxies, the shocks created as they run into one another, and the secret supermassive black hole obscured by dust.

Scientists, teachers, amateur astronomers, informal educators:

Do you plan on giving a presentation about #JWST? Did you know STScI has full slide decks available, geared towards a general audience, with extensive speaker notes and links to resources?

Check out the new slide deck celebrating one year of JWST science:

I'm at the American Astronomical Society's summer meeting this week in beautiful Albuquerque, New Mexico.

If you are at #aas242 come by the STScI booth and say hi!

We just updated the FAQs on WebbTelescope.org. Find answers to questions like:

• What is redshift? How can we tell the difference between an intrinsically red galaxy and one that has been redshifted?

•Has JWST taken deep field images? Will it observe the same deep fields as Hubble?

• Why does JWST’s mirror look like that?

• Why do stars in JWST’s images have spikes?

• Why do I see JWST images online that aren’t on your official site?

Researchers using #JWST were able to catch an enormous water plume from Saturn’s icy moon Enceladus. The plume is more than 20 times the size of the moon. Enceladus orbits Saturn every 33 hours, spraying water and leaving behind a torus—or “donut”—of material in its wake.

So movie aliens, if you’re considering invading Earth to steal our precious water, I would suggest taking a detour to Saturn 😉

Animation of the Saturn system and its moons, Mimas, Enceladus, Tethys, Dione, Rhea and Titan, with arcs showing the orbits of the Moons. A blue ring surrounds the second moon Enceladus. Zoom into Enceladus. A large plume, much larger than the moon itself, is seen coming from the moon’s south pole. Next, a real JWST image is superimposed on the animation, titled “Water Pulme and Torus Model”. The image appears pixelated. A single, white pixel is labeled “Enceladus.” The dark background is labeled “Water Torus.” Below the pixel representing Enceladus is a roughly triangular-shaped area of brighter blue pixels, which is narrower near the moon and gets wider as it extends to the bottom of the image. This is labeled “Plume” near the moon and “Extended Plume” near the bottom. The JWST image fades out, and we zoom into a 3D model of Enceladus based on Casini images. A light grey moon with a few craters has four bright spots, plumes, just below its south pole. This shows us a detailed view of the area that is a single, bright pixel in the JWST image, and the source of the large plume seen by JWST.
