The James Webb Space Telescope may have just found its first supernova

https://www.inverse.com/science/the-web … -supernova

Webb observed the galaxy, called SDSS.J141930.11+5251593, twice, five days apart; the object dimmed, just slightly, over those five days — classic supernova behavior.

Webb Captures Stellar Gymnastics in The Cartwheel Galaxy

https://www.nasa.gov/feature/goddard/20 … eel-galaxy

For everyone like me who's excited for JWST to observe the 7 planet system TRAPPIST-1 - it did so yesterday morning for over 5 hours

https://twitter.com/drbecky_/status/1548982149231132674

Here's what we learn when looking at the active galactic nucleus – a supermassive black hole – of the topmost galaxy in Stephan's Quintet with Webb's NIRSpec instrument

https://twitter.com/ESA_Webb/status/1549671992009302017

Here’s that galaxy again, as seen just through Webb’s MIRI instrument. While Webb’s NIRCam reveals previously unseen young stars, MIRI reveals regions rich in hydrocarbons and chemical compounds, such as silicate dust — similar to dust on Earth!

Yep.  Not a photo.  No telescope can do that much magnification.  Not in any band.

I'm surprised and disappointed to see something that misleading.

Turns out this was a French scientist posting a joke on Twitter.  It's really a closeup of a slice of sausage.

Snapshot: JWST captures psychedelic swirl of 'Phantom Galaxy'
https://astronomy.com/news/2022/08/snap … ime-stream

Get ready for a journey through space. In this short video, we zoom through space to the Cartwheel Galaxy, 500 million light-years away. At the end of the clip, you can see this new composite image by Webb's NIRCam and MIRI.
https://twitter.com/ESA_Webb/status/1557009138500210689

Time to reinvent the wheel.
Here’s the Cartwheel Galaxy in a whole new light — as a composite image from 2 instruments on the Webb telescope. Webb uniquely offers not just a snapshot of the galaxy’s current state, but also a peek into its past & future

In a single month, the James Webb Space Telescope has seen the oldest galaxies, messy cosmic collisions, and a hot gas planet's atmosphere
