Amazing James Webb image looks like a wormhole to another dimension

Early data from the James Webb Space Telescope is already starting to come in, with exciting finds like views of Jupiter and a potential sighting of the most distant galaxy ever observed. But there’s a lot more Webb data being shared, and much of it is publicly available through the Space Telescope Science Institute’s MAST archive. That means enterprising astronomers are already digging through James Webb data to perform their own analyses, and have created some amazing visuals.

Gabriel Brammer, an associate professor at the University of Copenhagen, composed and shared this incredible and faintly terrifying image on Twitter. It shows the galaxy Messier 74, captured in the mid-infrared range by Webb’s MIRI instrument as part of the PHANGS-JWST project.

A composite of 3 monochromatic images from the MIRI instrument at wavelengths 7.7, 10, and 11 µm. The striking purple filamentary structures are emission from interstellar dust and polycyclic aromatic hydrocarbon (PAH) molecules.

“Let’s just see what JWST observed yesterday …” Brammer wrote on Twitter. Then, echoing all of our sentiments, “Oh, good god.”

The image is this striking purple color because of the way the data is processed, in order to show off the structures of dust and hydrocarbons which swirl around the galaxy. The data used was taken on July 17 2022 at three different wavelengths in the mid-infrared: 7.7 µm, 10 µm, and 11 µm.

The galaxy looks very different in visible light wavelengths, as shown in this image of Messier 74 captured by the European Southern Observatory’s New Technology Telescope:

The James Webb data was collected as part of the PHANGS project, or Physics at High Angular resolution in Nearby GalaxieS, which is a survey that uses multiple different instruments including Hubble and ground-based telescopes to study how stars form from clouds of dust. The project will also work with Webb in order to peer through the clouds of dust which can otherwise obscure galaxies and get a clearer look at the star formation going on within.

The leader of the Webb part of the PHANGS research, Janice Lee of the National Science Foundation’s NOIRLab, said before the observations began that Webb could provide vital insights into understanding the life of stars: “JWST touches on so many different phases of the stellar life cycle – all in tremendous resolution,” Lee said in a statement. “Webb will reveal star formation at its very earliest stages, right when gas collapses to form stars and heats up the surrounding dust.”

James Webb captures a unique view of Uranus’s ring system
This image of Uranus from NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope shows the planet and its rings in new clarity. The Webb image exquisitely captures Uranus’s seasonal north polar cap, including the bright, white, inner cap and the dark lane in the bottom of the polar cap. Uranus’ dim inner and outer rings are also visible in this image, including the elusive Zeta ring—the extremely faint and diffuse ring closest to the planet.

A festive new image from the James Webb Space Telescope has been released, showing the stunning rings of Uranus. Although these rings are hard to see in the visible light wavelength -- which is why you probably don't think of Uranus as having rings like Saturn -- these rings shine out brightly in the infrared wavelength that Webb's instruments operate in.

The image was taken using Webb's NIRCam instrument and shows the rings in even more detail than a previous Webb image of Uranus, which was released earlier this year.

James Webb spots tiniest known brown dwarf in stunning star cluster
The central portion of the star cluster IC 348. Astronomers combed the cluster in search of tiny, free-floating brown dwarfs.

A new image from the James Webb Space Telescope shows a stunning view of a star cluster that contains some of the smallest brown dwarfs ever identified. A brown dwarf, also sometimes known as a failed star, is an object halfway between a star and a planet -- too big to be a planet but not large enough to sustain the nuclear fusion that defines a star.

It may sound surprising, but the definition of when something stops being a planet and starts being a star is, in fact, a little unclear. Brown dwarfs differ from planets in that they form like stars do, collapsing due to gravity, but they don't sustain fusion, and their size can be comparable to large planets. Researchers study brown dwarfs to learn about what makes the difference between these two classes of objects.

James Webb provides a second view of an exploded star
A new high-definition image from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) unveils intricate details of supernova remnant Cassiopeia A (Cas A), and shows the expanding shell of material slamming into the gas shed by the star before it exploded. The most noticeable colors in Webb’s newest image are clumps of bright orange and light pink that make up the inner shell of the supernova remnant. These tiny knots of gas, comprised of sulfur, oxygen, argon, and neon from the star itself, are only detectable by NIRCam’s exquisite resolution, and give researchers a hint at how the dying star shattered like glass when it exploded.

When massive stars run out of fuel and come to the ends of their lives, their final phase can be a massive explosion called a supernova. Although the bright flash of light from these events quickly fades, other effects are longer-lasting. As the shockwaves from these explosions travel out into space and interact with nearby dust and gas, they can sculpt beautiful objects called supernova remnants.

One such supernova remnant, Cassiopeia A, or Cas A, was recently imaged using the James Webb Space Telescope's NIRCam instrument. Located 11,000 light-years away in the constellation of Cassiopeia, it is thought to be a star that exploded 340 years ago (as seen from Earth) and it is now one of the brightest radio objects in the sky. This view shows the shell of material thrown out by the explosion interacting with the gas that the massive star gave off in its last phases of life.
