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

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!

Re: James Webb Space Telescope (JWST) - 6.5m mirror, L2 orbit

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.

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

NASA’s Webb Detects Carbon Dioxide in Exoplanet Atmosphere

https://www.nasa.gov/feature/goddard/20 … atmosphere

Trans-Neptunian object minor-planet studies, Eris, Haumea, Makemake, Gonggong, Quaoar, Sedna, Orcus, Salacia? In astronomy, the Hills cloud (also called the inner Oort cloud and inner cloud) is a vast theoretical circumstellar disc, interior to the Oort cloud, whose outer border would be located at around 20,000 to 30,000 astronomical units (AU) from the Sun, and whose inner border, less well defined, is hypothetically located at 250–1500 AU, well beyond planetary and Kuiper Belt object orbits—but distances might be much greater. If it exists, the Hills cloud contains roughly 5 times as many comets as the Oort cloud. Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravitational effects could explain the peculiar clustering of orbits for a group of Extreme trans-Neptunian objects (ETNOs). In the 1980s, astronomers realized that the main cloud could have an internal section that would start at about 3,000 AU from the Sun and continue up to the classic cloud at 20,000 AU. Most estimates place the population of the Hills cloud at about 20 trillion (about five to ten times that of the outer cloud), although the number could be ten times greater than that. The main model of an "inner cloud" was proposed in 1981 by the astronomer Jack G. Hills, from the Los Alamos Laboratory, who gave the region its name. A sednoid is a trans-Neptunian object with a perihelion well beyond the Kuiper cliff at 47.8 AU.  Some astronomers, such as Scott Sheppard, consider the sednoids to be inner Oort cloud objects (OCOs), though the inner Oort cloud, or Hills cloud, was originally predicted to lie beyond 2,000 AU, beyond the aphelia of the three known sednoids.

Observing the DARTMission impact with Webb was a unique challenge. The target moved over at a speed over 3 times faster than the original speed limit Webb was designed to track! In the weeks leading up to the impact, teams carefully tested for success.
