Is anybody else hella hype for the launch of the James Webb?
I’ve been following it for so long it feels like my kid is going away to college or something. 🤣

Totally! Instruments like the Webb come along once per generation. The Hubble Repair mission was the last time we got such a big boost in our ability to see deeper into the universe. And with the Webb out at L2, there won't ever be a chance for repair.

[quote]"These are among the lowest mass galaxies ever directly observed in the early universe," says Nor Pirzkal of the Space Telescope Science Institute and the European Space Agency in Baltimore, Md.
The conventional model for galaxy evolution predicts that small galaxies in the early universe evolved into the massive galaxies of today by coalescing. These nine Lego-like "building block" galaxies initially detected by Hubble likely contributed to the construction of the universe as we know it.
Pirzkal was surprised to find that the galaxies' estimated masses were so small. Hubble's cousin observatory, NASA's Spitzer Space Telescope was called upon to make precise determinations of their masses. The Spitzer observations confirmed that these galaxies are some of the smallest building blocks of the universe.
These young galaxies offer important new insights into the universe's formative years, just one billion years after the Big Bang. Hubble detected sapphire blue stars residing within the nine pristine galaxies. The youthful stars are just a few million years old and are in the process of turning Big Bang elements (primarily hydrogen and helium) into heavier elements. The stars have probably not yet begun to pollute the surrounding space with elemental products forged within their cores.[/quote]

And the Webb will look even [b]further[/b] back into the early universe! 100 million to 200 million years after the Big Bang!!

@MalteseFalconPunch I can't wait.
