This will never stop blowing my mind. A 12-year sequence of real telescope images of a star 133 lightyears away. And around it, four planets slowly orbiting. Four real exoplanets, each more massive than Jupiter, imaged as they move around their host star.

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."

These are what the clouds on Jupiter look up close. The small patches of white are cloud tops, soaring above the main, colourful cloud layer. Image from NASA's Juno spacecraft during its 38th close approach to Jupiter on 29 November 2021, processed by Kevin Gill (@kevinmgill.bsky.social)

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.
