Here's a way to explore something that is far out. *Way* far out!
I've been zooming in and exploring the interactive web viewer for the James Webb telescope's new deep field view. According to Anton Petrov's new video on this, there's about 800,000 galaxies(!) in this view, which is a tiny fraction of the whole night sky.
Our universe is insanely HUGE!
It's also incredible that everyone can explore these massive images on our browsers. Thanks to the astonomers that made this possible.

Hot new James Webb Space Telescope image just dropped. And this one's a banger.
Meet the galaxy cluster Abell S1063.
"This behemoth collection of galaxies, lying 4.5 billion light-years from Earth in the constellation Grus (the Crane), dominates the scene. Looking more closely, this dense collection of heavy galaxies is surrounded by glowing streaks of light, and these warped arcs are the true object of scientists’ interest: faint galaxies from the Universe’s distant past."
"With 9 separate snapshots of different near-infrared wavelengths of light, totalling around 120 hours of observing time and aided by the magnifying effect of gravitational lensing, this is Webb’s deepest gaze on a single target to date."
Incredible new #JWST deep field (120 hours!) released by folks from ESA/NASA Webb teams.
Not only is nearly everything in this image a galaxy (the two spiky stars are not), but those curved arcs are images of galaxies beyond this cluster, which are projected and warped into our view thanks to the power of gravity!
It's called a gravitational lens. To visualise what's happening, take a look at this diagram.
There are distant galaxies that we can't normally see. There's also a galaxies between them and us, with lots of mass.
This mass warps space-time and bends the distant galaxy light towards us so we see them.
I am amazed. You should be amazed. This is a really epic image.

A single clear night break in the clouds. So I took the opportunity to break out the telescope!
Despite the light pollution from Vivid, city lights from Sydney and my laptop charging cord dropping out — got four okish Astro images tonight.
1. Triffid Nebula
2. M83 face on spiral galaxy
3. NGC 3627, tilted spiral galaxy
4. The M4 globular cluster
Nice to have a clear night!
Quand les galaxies n’étaient que lumière : le mystère de la jeunesse cosmique sans poussière
How the oldest science in the world flourished in Toledo 1,000 years ago.
An international conference on the origins of galaxies pays tribute to the pioneering scientific cooperation between Muslims, Jews, and Christians that took place in Spain at the end of the Middle Ages.
