Abell 2744 - From NASA Marshall Space Flight Center - https://flic.kr/p/2jEgvxh
Galaxy clusters are the largest objects in the universe held together by gravity. They contain enormous amounts of superheated gas, with temperatures of tens of millions of degrees, which glows brightly in X-rays, and can be observed across millions of light years between the galaxies. This image of the Abell 2744 galaxy cluster combines X-rays from Chandra (diffuse blue emission) with optical light data from Hubble (red, green, and blue).

Je trouve ça sympa les objets lointains :-) mais la c’est un peu limite pour capturer les détails…

It did take a while, but I looked at the JWST data of the survey SLICE and created these images.

SLICE = Strong LensIng and Cluster Evolution

Gravitational lenses seen by JWST. #gravity #galaxycluster #lens #jwst #nasa #esa #canadianspaceagency

5 different lenses are shown here. The upper left is a large blue arc. The upper right is a brown arc that looks like a hill. The lower left and lower right are shaped like the letter S. The lower middle looks like an alien face.

A high-resolution telescopic image of Messier 109, a barred spiral galaxy seen face-on with a distinct central bar and tightly wound spiral arms. The galaxy glows with a soft bluish hue and appears near the lower center of the frame. Bright foreground stars with diffraction spikes dot the scene. In the upper right, the glare from the nearby bright star Phecda is visible. Three smaller, faint bluish galaxies — UGC 6969, UGC 6940, and UGC 6923 — appear scattered around the frame and may be satellite galaxies of M109.

A breathtaking image of the Coma Cluster, one of the densest galaxy clusters known. Thousands of galaxies, each containing billions of stars, are densely packed in this cosmic tapestry. Light from this cluster takes hundreds of millions of years to reach Earth, showcasing the immense scale of the universe. The image reveals the diverse shapes and sizes of these galaxies, mostly ellipticals, a characteristic of galaxy clusters. The mysterious nature of Coma's X-ray emission is a subject of ongoing research.
