There's something almost haunting about seeing our planet through the window of a spacecraft. Such as this view, from the Artemis II Crew in April.
A crescent Earth hangs in the darkness. Part of the frame of the Orion capsule can be seen at upper right. Various imperfections, lens flares, and reflections from the cabin are seen on the glass.

This is a photo of some rocks and sand. It was taken earlier today, with a camera 247,000,000 km away. It was taken on Mars. And now you're looking at it on your screen.
Dusty, red rocks, and red soil. Darker soil in the middle of the image marks where one of the rocks has been displaced.

This is a photograph of the edge of one of Saturn's rings, looking down from above. Those spiky dark shapes are shadows. Shadows of giant towers of ice and dust grains clumped together that rise up to three *kilometres* above the 10-m thick rings.
A series of bands cross the image from left to right, brighter at the bottom and darkening towards the top. A band of empty space is at the top of the image. About a quarter down from the top is a complex pattern of jagged, spiky shadows cast onto the rings. The icy towers casting the shadows are seen here at a highly oblique angle.

This is gravitational lensing. Where the a bunch of galaxies are so, so massive they distort the fabric of spacetime itself, and bend the light from background galaxies billions of lightyears more distant.
From the source: "A massive galaxy cluster, made of many golden elliptical galaxies with the largest, brightest one in the centre. Heavily distorted orange galaxies appear all around the cluster, the largest concentrated in a large arc around the cluster's centre; these are images of very distant galaxies, created by gravitational lensing. A few galaxies are large and bluish-white in colour; bright, nearby stars are the same colour."

A complex, swirling pattern of lighter and darker clouds. One large system, angled to the upper left in this scene, is a tawny brown colour and is elongate. Another, more circular storm system is at lower centre, and is a grey–greenish colour. The background swirls are various shades of grey to blue; small, white features dot the scene.

The @stsci.edu posted this JWST image from 2023 earlier today—and I had to do the same. This is only a portion (about 50 lightyears across) of the Milky Way's centre. In this view, there's an estimated half-million stars. In our night sky, at a dark site, humans can see ~2,000 stars unaided.
From the source: "In a field crowded with stars, a funnel-shaped region of space appears darker than its surroundings with fewer stars. It is wider at the top edge of the image, narrowing towards the bottom. Toward the narrow end of this dark region a small clump of red and white appears to shoot out streamers upward and left. A large, bright cyan-colored area surrounds the lower portion of the funnel-shaped dark area, forming a rough U shape. The cyan-coloured area has needle-like, linear structures and becomes more diffuse in the center of the image. The right side of the image is dominated by clouds of orange and red, with a purple haze."

This is a SMALL version of the largest JWST image released so far—of IC 348, a star-forming region about 1,000 lightyears away. Open up the image and marvel in the incredible beauty even in our galactic neighbourhood. This is what it looks like when stars are born.
From the source: "A star-forming region. It is blanketed in thick clouds of gas and dust, millions of kilometres across, that form swirling patterns. Bright stars are scattered throughout the clouds, with the densest cluster situated in the centre of the scene. Each is crowned with six long points created by the optics of the telescope’s mirrors. In the upper right, a couple of hidden stars blast out long, glowing jets of material."

Another stunner from JWST—this time part of a *much* larger scene I'll post later. This portion is made up of stars and protostars in a cluster about 1,000 lightyears from Earth. The bright, multi-point features are nearby stars. The smaller features in the background are other galaxies.
From the source: "A star-forming nebula that contains young stars called protostars. Two of these protostars are shooting out long jets that are colliding with the nebula, creating glowing, colourful outflows. A few other protostars create orange and red areas in the nebula. Most of the image is covered by blue gas, with brighter areas, denser clouds and dark gaps; the bottom-left corner contains greenish-yellow gas."
