This is a new image from #JWST. The bright points with spikes are stars in the Milky Way. Everything else is a galaxy. Everything. Else. Is. A. Galaxy.

🧵 This breathtaking image from #JWST, published last April 29, depicts a cosmic field filled with thousands of galaxies. THOUSANDS OF GALAXIES! Stars, marked by diffraction spikes, are within the Milky Way. Reference➡️ esawebb.org/images/potm2... 🔭 🧪 #stellarastro #cosmology #Universe #Webb

The image shows an area of deep space teeming with thousands of galaxies, like a bright mosaic on a deep black background. In the center, slightly lower, stands out a group of gold-white galaxies that shine brightly, like a cluster of gems. Around them, galaxies of various shapes dot the scene: some are spirals with curved arms, others are elliptical and smooth, still others have distorted shapes. The colors vary from white and blue for nearby galaxies to red for distant ones. Stars of the Milky Way appear as bright points with thin rays radiating outward, like small sparkling spikes. The overall effect is a dense and vibrant cosmic carpet, full of light and movement.

Did you know Jupiter has rings? You can see them, faintly, in this infrared image from #JWST. The giant planet's aurorae (at both poles) are also clearly visible, as are a few of its irregular, inner moons (the largest of which, Amalthea, is at the far left).

🧵 1/ For those who missed it, this recent image from Webb's NIRCam features a part of the Leo P dwarf galaxy (the blue stars at lower right) along with countless other galaxies in the background. Reference➡️ esawebb.org/images/LeoP/ A team's research, done 🔭 🧪 #extragalactic #Webb #JWST

Hello new Bluesky friends! Very happy to be here. For my first post, here's my favorite (still!) #jwst image - the Cosmic Cliffs of Carina 🤩 This image made me cry the first time I saw it. It's just so beautiful, and this is a good time to appreciate the beauty around and above us ✨

In a historic first, the James Webb Space Telescope has performed a direct mass measurement of a black hole in the early Universe. Located 13 billion light-years away, this black hole weighs in at a massive 50 million times the mass of the Sun. #JWST #SpaceNews #Astronomy 1/4

Image description: Image showing hundreds of bright objects of different size, colour, and shape on the black background of space. Colours range from white to deep red. Shapes include elliptical, spiral, dot-like, dash-like, and arcuate.Three objects in the central part of the image are called out with small white boxes that contain images of the three objects. From top to bottom these are labeled QSO1A, QSO1B, and QSO1C. At the centre of each box is a tiny, circular red dot. QSO1A (top) is notably larger, brighter, and clearer than the other two. QSO1B, in the middle, is the smallest and fuzziest, and is somewhat washed out by the light of a larger white object next to it.]

1/6 #JWST captured a cloud of gas and dust having an unusual and fascinating shape. 🔭 Located 7,500 light-years away, in the Carina Nebula, it is a cometary globule called the Treasure Chest.🧪 esawebb.org/images/potm2... #galactic #astronomy #stars ⚛️

This patch of space holds plenty of bright stars mixed in with thick gas and dust. The densest stuff sits dead center and looks just like a treasure chest with the lid thrown open. Light glows out from inside it. At its base it breaks into long, thick pillars of gas. In the background many small dark-orange globules sit among larger, softer pale hazes. A handful of vivid foreground stars stand out, the largest and brightest positioned just in front of the chest’s open lid.

🧵 This intriguing NIRCam (Near-Infrared Camera) image from #JWST shows, in incredible detail, a view of remnant supernova Cassiopeia A (Cas A), including the expanding shell of material flapping into the gas shed by the star before its explosion. ➡️ nasa.gov/missions/web... 🔭 🧪 #galactic
