"Galaxy clusters make my ape brain hurt.
A galaxy is an immense thing, a vast collection of billions —
hundreds of
billions — of stars, as well as gas, dust, and dark matter. They are thousands
of light-years across, with our own Milky Way a soul-crushing 120,000
light-year diameter.
Yet, there are bigger structures. Galaxy clusters are themselves collections of
galaxies, some with hundreds, some with
over a thousand. They can stretch for
millions of light-years and dominate all of space around them.
Abell S1063 is one such cluster. It’s a long way off, about 4.5 billion
light-years, so the light we see from it left the cluster when the cosmos
itself was about 2/3rd its present age. It is colossal, with at least 1,234
member galaxies.
Hubble observed it in 2016, and the image was amazing. But now JWST has taken a
peek at it, and the image is jaw-dropping. Prepare your brain, but you cannot.
You
cannot."
