Webb Deep Field. If you hold a grain of sand on your finger tip and stretch your arm out, that's the area looked at in this image, unbelievable.

NASA’s James Webb Space Telescope has delivered the deepest and sharpest infrared image of the distant universe so far. Webb’s First Deep Field is galaxy cluster SMACS 0723, and it is teeming with thousands of galaxies – including the faintest objects ever observed in the infrared.

Webb’s image is approximately the size of a grain of sand held at arm’s length, a tiny sliver of the vast universe. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying more distant galaxies, including some seen when the universe was less than a billion years old.

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. This is now my lock screen.

Southern Ring Nebula previous out of sight of astronomers.
Some stars save the best for last.

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 colours of light, is the most detailed of its kind to date, demonstrating Webb’s unprecedented ability to analyse atmospheres hundreds of light-years away.

While the Hubble Space Telescope has analysed 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.

Possible sign of life on Venus stirs up heated debate

“Something weird is happening” in the clouds of the planet next door—but some experts are raising doubts about the quality of the data.

Just watched a recording of the story of the James Webb, right up to date, including latest images. Excellent. The teams of scientists and engineers who devised each tiny step of the build should be honoured with a commemorative (something) to each and every one of them for their sterling work. And a special prize for the thermal engineer who solved a mystery 5 days into the mission.
I printed off the Carina Neb and am going to frame it

Last night watched the story of Pathfinder, 60 mins long. How they struggled to get a team together from a hoard of sceptics who said you cant land a robot on mars. Right the way through. Love the quote from team Boss Tony Sharp; "if a member of the team knows what he is doing, I stay away, let them get on with it." The triumphant scenes when pathfinder sent that famous signal back is highly charged emotion. The boss of JPL was crying with emotion. Everyone said they would fail, Tony Sharp said we can (and did) do it.

excellent, so excellent -

James Webb Space Telescope discovers candidates for most distant galaxies yet

The two galaxies, if confirmed, existed 300 to 400 million years after the Big Bang.

China have been throwing sats up like there's no tomorrow. They have been 'typical vague' about it, but their orbital angles cover the whole planet. SPYing. 27 this year to date. How Long (pun intended) before crashes occur. 500 miles up on a 35 deg orbit.
