This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks.
The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago.
Unimaginable how “nothing” we really are… just mind boggling.
Earth formed 4.5 billion years ago so we're seeing something that existed while there wasn't even this planet. Talk about completely mind-blowing.
Yes i think 13.5 billion or somethingSome details here:
NASA’s Webb Delivers Deepest Infrared Image of Universe Yet - NASA
NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of the distant universe to date. Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.www.nasa.gov
In addition to what @MJ DeMarco said about the grain of sand:

I've extracted the JW Telescope pics and conversation (out of Random Chat) to its own thread.
I get the feeling we're going to be talking about a TON of these pictures ... it deserves its own thread.
That “mountainous” looking picture is just unbelievable… I thought it was a book cover or a “fantasy” image created to compare to the actual photos.James Webb's first images:

"This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.
Called the Cosmic Cliffs, Webb’s seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peaks” in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image."
"Stephan’s Quintet, a visual grouping of five galaxies, is best known for being prominently featured in the holiday classic film, “It’s a Wonderful Life.” Today, NASA’s James Webb Space Telescope reveals Stephan’s Quintet in a new light. This enormous mosaic is Webb’s largest image to date, covering about one-fifth of the Moon’s diameter. It contains over 150 million pixels and is constructed from almost 1,000 separate image files. The information from Webb provides new insights into how galactic interactions may have driven galaxy evolution in the early universe."
"The dimmer star at the center of this scene has been sending out rings of gas and dust for thousands of years in all directions, and NASA’s James Webb Space Telescope has revealed for the first time that this star is cloaked in dust.
Two cameras aboard Webb captured the latest image of this planetary nebula, cataloged as NGC 3132, and known informally as the Southern Ring Nebula. It is approximately 2,500 light-years away.
Webb will allow astronomers to dig into many more specifics about planetary nebulae like this one – clouds of gas and dust expelled by dying stars. Understanding which molecules are present, and where they lie throughout the shells of gas and dust will help researchers refine their knowledge of these objects."
"NASA’s James Webb Space Telescope has captured the distinct signature of water, along with evidence for clouds and haze, in the atmosphere surrounding a hot, puffy gas giant planet orbiting a distant Sun-like star.
The observation, which reveals the presence of specific gas molecules based on tiny decreases in the brightness of precise colors of light, is the most detailed of its kind to date, demonstrating Webb’s unprecedented ability to analyze atmospheres hundreds of light-years away.
While the Hubble Space Telescope has analyzed numerous exoplanet atmospheres over the past two decades, capturing the first clear detection of water in 2013, Webb’s immediate and more detailed observation marks a giant leap forward in the quest to characterize potentially habitable planets beyond Earth.
WASP-96 b is one of more than 5,000 confirmed exoplanets in the Milky Way. Located roughly 1,150 light-years away in the southern-sky constellation Phoenix, it represents a type of gas giant that has no direct analog in our solar system. With a mass less than half that of Jupiter and a diameter 1.2 times greater, WASP-96 b is much puffier than any planet orbiting our Sun. And with a temperature greater than 1000°F, it is significantly hotter. WASP-96 b orbits extremely close to its Sun-like star, just one-ninth of the distance between Mercury and the Sun, completing one circuit every 3½ Earth-days."

Thanks, I somehow missed this thread.
Despite having studied space science for almost a year now this still boggles my mind. Only one word can describe this: Beautiful.
If they could get decent images of an exoplanet 1,000+ ly, what would Proxima Centauri b look like!? ('only' 4 ly, closest known exoplanet). Possibly view it's surface?Thanks, I somehow missed this thread.
These first images are.. mind-blowing, to say the least.
Oh, and about that last image that shows the atmosphere composition of the WASP-96 B exoplanet...
Well, let's just say that NASA managed to figure out - in great detail - what the atmosphere of a planet 1,150+ light-years away from Earth consists of.
For reference:
1 light-year = 6 trillion miles
1,150 light-years = about 6.8 quadrillion miles
If they could get decent images of an exoplanet 1,000+ ly, what would Proxima Centauri b look like!? ('only' 4 ly, closest known exoplanet). Possibly view it's surface?
I hope so too, this is certainly very exciting.They're probably doing that shit as we speak. Hopefully, they'll throw us a bone as well soon...
but who needs a granite countertop when you could buy a 1/1 reflection of the universe?Y'all are really buying this NASA propaganda?
Reminder that each galaxy in that image has a few billion/a few trillion stars
Would love to read more about the limits of the JW Telescope. I think I remember that (years ago) people were complaining about the range of the wavelength coverage.If they could get decent images of an exoplanet 1,000+ ly, what would Proxima Centauri b look like!?

Yes, basically the more distant the object the further back in time it appears, having to do with the way light travels.Would love to read more about the limits of the JW Telescope. I think I remember that (years ago) people were complaining about the range of the wavelength coverage.
I suppose interesting wavelengths could be missing that are relevant for the use case.
Not sure I understand that correctly, but it seems to be optimized for looking further back into the past because hubble could not pick up important information due to the cosmological redshift.
There might be other optimizations that render the JW Telescope suboptimal for looking at younger and closer objects, but this is just speculation.
I am always trying to understand next steps and appreciate that we get a glimpse in the longer term plans of some people. But I think the warp drive is mostly a thought experiment for now, which I will worry about if Elon manages to speedrun Factorio in real life ;-). Would love to read more about how a space industry and economy could develop. Feels like we have to turn to 80s literature to rediscover the state of the art ... which worries me a little.Yes, basically the more distant the object the further back in time it appears, having to do with the way light travels.
Due to the hypothetical expansion of the universe, galaxies are moving further and further away from each other (the most common example it dots on a balloon - while deflated the dots are close, but as the balloon expands the dots separate - the dots being galaxies. Because JW uses infrared I think can pick up objects that are normally out of reach. According to NASA, "Infrared energy can also reveal objects in the universe that cannot be seen in visible light using optical telescopes" and "have longer wavelengths than visible light and can pass through dense regions of gas and dust in space with less scattering and absorption". Pretty cool stuff.
This means that we can detect much more faint and distant objects: for instance, this image of a nebula directly imaged vs infrared; Notice you can see stars and galaxies in the background of the 2nd one rather than the first.
I heard that they are developing more space observatories for finding distant exoplanets, and high speed lightweight spacecrafts to fly between star systems!
In fact, this will sound crazy but NASA is also working on a warp drive - Yes, like the ones in Star Wars! (probably won't happen for a long long time but they've started with some concepts)
I'm not sure how exactly it will work (I'm not a rocket scientist) but from what I understand it creates some kind of bubble in space time to ignore the universal speed limit of light.
I look forward to seeing what comes next!
Luckily, our galaxy's starlight will probably always be there for us to see, as all the stars we see when we look up with the bare eye are confined to our own galaxy. However, what will disappear is the light of stars from other, distant galaxies. But an even scarier thought is that the universe is thought to stop expanding one day and begin retracting back to singularity!It's eerie to think that given the rate at which the universe is continuing to expand, objects in space will be so far apart, there will be no light from other stars. You will look up at the sky, and it will just be emptiness.
I first learned about it while listening to a space documentary and did a bit more research - the warp drive seems to be entirely a concept at the moment, however there is science behind it and I want to see Star Wars tech IRL one day!I am always trying to understand next steps and appreciate that we get a glimpse in the longer term plans of some people.

Quite the ups and downs in the news. Damage more severe than initially expected, announced right after they celebrated that there is enough fuel for 20 years. Now we have to hope that it was inital bad luck and not an indicator for what is to come. Otherwise the JW Telescope might be rendered more and more useless faster than expected.
F*cking outstanding..........
F*ck Mars.........until it's terra formed you'll be living in a bubble...or underground....and have to wear a suit whenever you go outside. Put on some scuba gear and go visit a desert to see what it would be like......lol.......I first learned about it while listening to a space documentary and did a bit more research - the warp drive seems to be entirely a concept at the moment, however there is science behind it and I want to see Star Wars tech IRL one day!
Intergalactic space, here we come!
I do hope we can colonize Mars one day though - it would be so cool to see Mars in the sky knowing there's a civilization on there!
I DO love the idea of a warp drive...........FTL is the future.............ZI first learned about it while listening to a space documentary and did a bit more research - the warp drive seems to be entirely a concept at the moment, however there is science behind it and I want to see Star Wars tech IRL one day!
