This isn’t the farthest back we’ve observed. Non-infrared missions like COBE & WMAP saw the universe closer to the Big Bang (~380,000 years after), when there was only microwave background radiation, but no stars or galaxies. Webb sees a few 100 million years after the Big Bang.
@NASA@esa@csa_asc@SpaceTelescope Yesterday, we shared the first image from Webb: galaxy cluster SMACS 0723. See the same target, viewed by @NASAHubble in 2017. Webb was able to capture this image in less than one day, while similar deep field images from Hubble can take multiple weeks.
@NASA@esa@csa_asc@SpaceTelescope@NASAHubble Compare Webb’s Mid-Infrared (L) & Near-Infrared (R) views. Lens flares? Nope, the spikes you see are when light from bright objects like stars is bent by the edges of the telescope. They’re less prominent in mid-infrared.

The “Cosmic Cliffs” build on the legacy of Hubble’s imagery of the Carina Nebula, seen here. Webb’s new view gives us a rare peek into stars in their earliest, rapid stages of formation. For an individual star, this period only lasts about 50,000 to 100,000 years.
🌟 A star is born!
Behind the curtain of dust and gas in these “Cosmic Cliffs” are previously hidden baby stars, now uncovered by Webb. We know — this is a show-stopper. Just take a second to admire the Carina Nebula in all its glory: https://t.co/tlougFWg8B #UnfoldTheUniverse
Two cameras are better than one, as seen in this combined view from Webb’s NIRCam & MIRI! In the near-infrared, we see hundreds of stars and background galaxies. Meanwhile, the mid-infrared shows us dusty planet-forming disks (in red and pink) around young stars.
It's time. #UnfoldTheUniverse with us, and join the global watch party for the first full-color images from the world's most powerful space telescope, @NASAWebb. https://t.co/iLDER3c8k6 https://t.co/iLDER3c8k6
👀 Sneak a peek at the deepest & sharpest infrared image of the early universe ever taken — all in a day’s work for the Webb telescope. (Literally, capturing it took less than a day!) This is Webb’s first image released as we begin to #UnfoldTheUniverse: https://t.co/tlougFWg8B
UPDATE: One image from @NASAWebb will be previewed today by President Biden at 5:30pm ET (21:30 UTC) ahead of the full set of full-color images & data to be revealed July 12 at 10:30am ET (14:30 UTC): https://t.co/GQefRcrO9e
Images will be posted at: https://t.co/63zxpNDi4I
“Go all the way.
Despite rejection and the worst odds.
And it will be better than anything else you can imagine.
If you’re going to try, go all the way.
There is no other feeling like that.
You will be alone with the gods and the nights will flame with fire.”
-C. Bukowski
I’ve been very anxious about the Match, so here are some of the drawings I have made these last couple of weeks. It helps distract me a lot and boosts my creativity, so win-win. Wishing the best of luck to everyone!
