New JWST image just dropped.

This object is called Herbig-Haro 49/50. It's the outflow of a still-forming star hidden from view to the lower right of the orangish cone of material oriented diagonally in this image.

As stars form they eject excess matter in the direction of their poles of rotation. That material encounters the interstellar medium in the vicinity and lights up in response. "Like the wake of a speeding boat, the bow shocks in this image have an arc-like appearance as the fast-moving jet from the young star slams into the surrounding dust and gas."

Purely by coincidence, the outflow lines up with a distant background galaxy, which is the circular pinkish/blue object at upper left.

NASA’s James Webb Space Telescope observed Herbig-Haro 49/50, an outflow from a nearby still-forming star, in high-resolution near- and mid-infrared light. The intricate features of the outflow, represented in reddish-orange color, provide detailed clues about how young stars form and how their jet activity affects the environment around them. Like the wake of a speeding boat, the bow shocks in this image have an arc-like appearance as the fast-moving jet from the young star slams into the surrounding dust and gas. A chance alignment in this direction of the sky provides a beautiful juxtaposition of this nearby Herbig-Haro object with a more distant spiral galaxy in the background. Herbig-Haro 49/50 gives researchers insights into the early phases of the formation of low-mass stars similar to our own Sun. In this Webb image, blue represents light at 2.0-microns (F200W), cyan represents light at 3.3-microns (F335M), green is 4.4-microns (F444W), orange is 4.7-microns (F470N), and red is 7.7-microns (F770W).

You ever hear a fact that utterly blows your mind? That would be impossible to believe if there weren't photographic evidence?

Saturn's rings can be counted like rings on a treestump. They tell the story of the entire Saturn system's history.

What's more, they aren't rings, they are spirals. The gravitational mechanics of Saturn's rings work similarly to galactic arms, only wound more tightly.

The density waves that are formed by "shepherd moons" aren't one-directional, either. In one of the pics attached, the gravitational wake of the moon Daphnis can be seen throwing up waves perpendicular to the plane of the rings.

This image shows the different types of rings on saturn. Additional details for this image are found here: https://science.nasa.gov/resource/two-kinds-of-wave/
The bottom third of the image is filled with darkness. The top two thirds show the rings of saturn, forming patterned density waves vertically. In the center of the image there is a gap in the rings, and the moon Daphnis can be seen sweeping out a path. Both in front of and behind the moon, waves of ring dust are being created in a plane perpendicular to the camera and the rest of the ring structures.
A tilted, near-side on view of saturn's rings. Density waves can be seen in the ring spirals, with different densities corresponding to historic gravitational changes in the Saturn system
