Two pictures of Jupiter leaked by James Webb Telescope team

The composite shows a short-wavelength image of Jupiter on the left, and a long-wavelength image on the right, revealing the kinds of dramatically different atmospheric conditions that the JWST is able to spot.

The additional images of Jupiter were included in a commissioning document

What's amazing is you can see the rings of Jupiter.

The small meteoroid collision incident in May is making its rounds again, can be ignored.

Yes, a tiny rock particle hit the Webb telescope. No, the mission isn't nearly doomed.

You may have read misleading headlines emphasizing that the James Webb Space Telescope — the most powerful such observatory ever built — has incurred some permanent damage. That's a cherry-picked bit from a new 55-page report describing the instrument's excellent scientific performance over the past six months, as engineers prepped and tested its unprecedented cosmic-viewing abilities.

The Webb telescope, overall, is in great shape.

It's not a calamity.

How to Follow Webb’s Next Steps​

More images are coming. Webb has already captured more images beyond the ones you saw on July 12, and the Cartwheel Galaxy is just one example. Hold onto your intergalactic hats — we’ll be rolling those out in the coming weeks at nasa.gov/webb and on the NASAWebb social media channels. Some of those images give a first look at Webb’s capabilities, but are not part of science programs.

NASA’s Webb Takes Its First-Ever Direct Image of Distant World​

Editor’s Note: This post highlights images from Webb science in progress, which has not yet been through the peer-review process.

For the first time, astronomers have used NASA’s James Webb Space Telescope to take a direct image of a planet outside our solar system. The exoplanet is a gas giant, meaning it has no rocky surface and could not be habitable.

The image, as seen through four different light filters, shows how Webb’s powerful infrared gaze can easily capture worlds beyond our solar system, pointing the way to future observations that will reveal more information than ever before about exoplanets.

This image shows the exoplanet HIP 65426 b in different bands of infrared light, as seen from the James Webb Space Telescope: purple shows the NIRCam instrument’s view at 3.00 micrometers, blue shows the NIRCam instrument’s view at 4.44 micrometers, yellow shows the MIRI instrument’s view at 11.4 micrometers, and red shows the MIRI instrument’s view at 15.5 micrometers. These images look different because of the ways the different Webb instruments capture light. A set of masks within each instrument, called a coronagraph, blocks out the host star’s light so that the planet can be seen. The small white star in each image marks the location of the host star HIP 65426, which has been subtracted using the coronagraphs and image processing. The bar shapes in the NIRCam images are artifacts of the telescope’s optics, not objects in the scene. (Unlabeled version.) Credit: NASA/ESA/CSA, A Carter (UCSC), the ERS 1386 team, and A. Pagan (STScI).

“This is a transformative moment, not only for Webb but also for astronomy generally,” said Sasha Hinkley, associate professor of physics and astronomy at the University of Exeter in the United Kingdom, who led these observations with a large international collaboration...

The exoplanet in Webb’s image, called HIP 65426 b, is about six to 12 times the mass of Jupiter, and these observations could help narrow that down even further. It is young as planets go — about 15 to 20 million years old, compared to our 4.5-billion-year-old Earth...

with the image above,^^^
what if were looking at a world that has long ago vanished and its "light" has only just reached us.

and for my conspiracy nut job question of the day,
how do we know were actually seeing everything unfiltered from Webb?
there isn't some algorithms and subroutines filtering out Dyson spheres and Alien constructs.

So what if that was the case?
But I strongly doubt it, they will first be examining closer (and larger) opportunities to see how much Webb can reveal of exoplanets.
Just google its name for further info if you want.

The star HIP 65426 is located about 356.2 light-years (109.2 pc) away from our Solar System.

And as the article above mentions it's a very young star, so zero chance of it being dead

Further (see orig. article for these details) , they picked a planet that's very far from its star to make it initially easy to use the coronagraph starlight-blocking technology - about 100 times further away than Earth is from the sun.

again, you haven't answered my question,
what if the star itself is long ago dead, and its Light "shows" its very young age right now,

I mean were talking about light years and extremely distant and far off places,
almost as if were standing in Shanghai, and trying to see if somebody in Bloemfontein is having Chinese Food or Pizza for Lunch.

I suggest learn the science, understand why it's reliable, then come back if need be...

Quite possible with Webb btw, they even mentioned that it can see a single candle on one of Jupiter's moons..

For those who still don't know, there's a new worry going on;

Mid-Infrared Instrument Operations Update​

The James Webb Space Telescope’s Mid-Infrared Instrument (MIRI) has four observing modes. On Aug. 24, a mechanism that supports one of these modes, known as medium-resolution spectroscopy (MRS), exhibited what appears to be increased friction during setup for a science observation. This mechanism is a grating wheel that allows scientists to select between short, medium, and longer wavelengths when making observations using the MRS mode. Following preliminary health checks and investigations into the issue, an anomaly review board was convened Sept. 6 to assess the best path forward.

The Webb team has paused in scheduling observations using this particular observing mode while they continue to analyze its behavior and are currently developing strategies to resume MRS observations as soon as possible. The observatory is in good health, and MIRI’s other three observing modes – imaging, low-resolution spectroscopy, and coronagraphy – are operating normally and remain available for science observations.

I guess these are the risks of complex systems, something could well give in :- (

Re above post - they think they've figured it out and that it's okay longer term, taking it slow though;

With JWST Fully Operational Again, we get Images Like This: Saturn’s Moon Titan​

On August 24th, a vital instrument aboard the James Webb Space Telescope (JWST) experienced a malfunction that prompted the mission team to take it offline. The problem occurred when the Mid-Infrared Instrument (MIRI) experienced increased friction in one of its wheels while in Medium-Resolution Spectroscopy (MRS) mode. The mission team took MIRI offline while they attempted to diagnose the problem, leaving the observatory to continue making observations in other modes.


This came shortly after Webb was hit by a large micrometeoroid in late May that caused damage to one of its primary mirror segments. Luckily, the damage this caused will not alter the telescope’s performance, and the mission team announced earlier this month that they had restored the MIRI to operational status. With everything in the green, Webb has once again turned its infrared optics to the cosmos and acquired some breathtaking images. This includes a new image of Saturn’s largest moon Titan, which recently appeared online.

James Webb Space Telescope Operations Update​

The James Webb Space Telescope resumed science operations Dec. 20, after Webb’s instruments intermittently went into safe mode beginning Dec. 7 due to a software fault triggered in the attitude control system, which controls the pointing of the observatory. During a safe mode, the observatory’s nonessential systems are automatically turned off, placing it in a protected state until the problem can be fixed. This event resulted in several pauses to science operations totaling a few days over that time period. Science proceeded otherwise during that time. The Webb team adjusted the commanding system, and science has now fully resumed.

The observatory and instruments are all in good health, and were not in any danger while Webb’s onboard fault management system worked as expected to keep the hardware safe. The team is working to reschedule the affected observations.

James Webb space telescope brings insight into birth of stars at ‘cosmic noon’ with image of NGC 346 cluster

Scientists have been given an unprecedented glimpse into the birth of stars and the early stages of the universe, after a new image showing a cluster more than 10bn years ago was released by the James Webb space telescope.

The image shows a young cluster of stars, known as NGC 346, which is more than 200,000 light years from Earth.
