Webb Observes Tiny Galaxies From The Early Universe

This is a picture of Abell 2744, nicknamed Pandora’s cluster, a giant galaxy cluster at a distance of 4 billion light years. Pandora’s cluster is the product of a merger of at least four smaller galaxy clusters. With its large mass, it is a gravitational lens. It allows the James Webb Space Telescope to observe objects from the early universe that are much further away. The white symbols show the position of 20 of the 83 newly discovered young galaxies. These 20 galaxies were selected for deeper study.
This image shows the position of three of the tiny galaxies, called "green peas", when the universe was 790 million years old. The green glow comes from doubly ionized oxygen that was shifted into the infrared as it traversed the expanding universe.
The spectra taken with the James Webb Space Telescope’s NIRSpec instrument show strong signals of doubly ionized oxygen. This indicates a high star formation rate.
The oval green object at the center is the tiny galaxy 41028 with an estimated mass of just 2 million solar masses. On the right side there is a white blob. 41028 was formed during the period of reionization 150 million to 1 billion years after the Big Bang. The first generation of small galaxies provided enough UV radiation to ionize all the neutral hydrogen in the universe.
The Webb telescope captured this beautiful image of Pandora's cluster. Astronomers found about
50,000 sources of near-infrared light. Every white object surrounded by a hazy glow is a galaxy of Pandora’s Cluster.

Here's a section of the sky that Hubble focussed on a few years ago. Every dot is a galaxy, each containing billions of stars. Then it zooms out to show you that section in the night sky next to the Moon..

This needs more upvotes .. ALL your posts do :(

Thank you very much. :)

if you were on a planet in Abell 2744, nicknamed Pandora’s cluster, and you pointed a webb-type telescope to the same direction/degrees that the webb telescope is pointed, would you see an even earlier part of the universe, another 790 million light years away? did I just blow your mind? /s
Oktay74tn
If you were somewhere in Pandora's cluster, you would see the galaxy 41028 as it was 4 billion years later.

There's no green stars, but there is green galaxies? Wow, they must be seriously hot to be able to cook that much gas to make it look green to us. Wow!

And there are still people that think we are anything more than the current dominate species on one tiny planet that is part of what appears to be an ever evolving and expanding Universe .

That’s great. But can it see why kids love the taste of Cinnamon Toast Crunch??

The biggest news currently is Dark Matter is no more when the missing mass has been found as normal super heated extremely dispersed gas which is found in the void between galaxies. Early days though so it requires independent confirmation.

It’s amazing that scientists can learn so much from a single photo of things billions of miles away. Like I know alot of it is stuff we learn in high school but still, it’ll like to stop and appreciate these sorts of things.

"Green peas." So why isn't the cluster called The Pod?

Quote of Renato Dupke from https://esahubble.org/news/heic1111/ : “We nicknamed it Pandora’s Cluster because so many different and strange phenomena were unleashed by the collision. Some of these phenomena had never been seen before."

Those green blobs aren't galaxies, they're Borg Cubes just waiting to assimilate us.
Oktay74tn
Or species 8472, which is worse :)

I listened yo "there is a white blob" like six times. Quacks me up.
Oktay74tn
Sorry, it reminded me of the movie "The blob". :)

A 'tiny galaxy' with an estimated mass of just 2 million solar masses. I can't get my head around how big 2 million solar masses would be.
Oktay74tn
Some of the tiny satellite galaxies of the Milky Way have also masses in the order of million solar masses. The Milky Way has a mass of 200 billion solar masses. Andromeda has a mass of 1 to 2 trillion solar masses. Sagittarius A*, Milky Way's central supermassive black hole has a mass of 4.3 million solar masses.

Stop it! You're making my brain hurt.
ItHappenedInThe20thCentury
To be fair, I can't get my head around what 1 solar mass actually is, when I think of it. You know, about 99% of the mass of the entire solar system. Heck, I can't really fathom Jupiter already.

Have you ever looked at a mountain and wondered how much it weighs? What we're both describing is what Emmanuel Kant described as the sublime. Things in nature so immense in concept, if not size, that you simply can't comprehend it.
