In imagine se disting doua tipuri de galaxii: unele portocalii-rosii deformate de lentila gravitationala, si unele colorate "normal". Cine stie, cele din prima categorie poate vin din negura timpului si au ajuns atat de deformate incat asa le vedem. Din cate am inteles una din ele apare de doua ori, probabil apar reflexii interne intre lentilele gravitationale...
Cele din a doua categorie apar distribuite normal, adica fara o aranjare anume.

Arata ca un astigmatism sagital. Explicatii de la NASA:

Other features include the prominent arcs in this field. The powerful gravitational field of a galaxy cluster can bend the light rays from more distant galaxies behind it, just as a magnifying glass bends and warps images.

The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions, as Webb seeks the earliest galaxies in the universe.

Am senzația că în spate ar mai fi o lentilă gravitațională .
Poate suntem martorii unei lunete gravitaționale !.

Intrebare de sah mat : luneta Kepler sau Galilei ?
Ca de asta depinde unde se afla in realitate fiecare galaxie din imagine.

Ma rog ... unde era, inainte de 1900 toamna sau 1000 toamna ... sau ...

Adaug si doua poze. Arata mai decent decat primele.
