Over the last two years, scientists have used NASA’s James Webb Space Telescope (also called Webb or JWST) to explore what astronomers refer to as Cosmic Dawn – the period in the first few hundred million years after the big bang where the first galaxies were born. These galaxies provide vital insight into the ways in which the gas, stars, and black holes were changing when the universe was very young. In October 2023 and January 2024, an international team of astronomers used Webb to observe galaxies as part of the JWST Advanced Deep Extragalactic Survey (JADES) program. Using Webb’s NIRSpec (Near-Infrared Spectrograph), they obtained a spectrum of a record-breaking galaxy observed only two hundred and ninety million years after the big bang. This corresponds to a redshift of about 14, which is a measure of how much a galaxy’s light is stretched by the expansion of the universe
Existential crisis about how every narrow image shows 100,000x the amount of matter and bodies that I already can’t conceptualize from just our own galaxy
They really expect us to believe this shit!? Those are definitely large alien spiders that are coming to the surface to mate and multiply as they prepare to attack Earth. I need to join up with United Citizen Federation, quick. I suggest you all do the same…
I know that's not how the phrase is meant to be read, but I can't unsee it as it flying separately by the earth and the moon and deciding to buzz one of the two a bit closer.
Pictures turned out ok! I should have done a dry run for my totality setup, as I wanted to do some bracketed exposures and assumed my DSLR would let me do that the same way in live display mode as it does in optical viewfinder mode, and it… didn’t. But the pictures I did get are a reasonable, if insufficient facsimile of the experience.
As for the real deal… I’ll have to update everyone once I’ve processed it. It was clear as crystal, and a perfect day. I was totally unprepared in every way that mattered. I don’t yet have words.
