"James Webb telescope takes emergency look at 'city-killer' asteroid 2024 YR4 ahead of close encounter in 2032" by @LiveScience - #NASA #JWST observations confirm #asteroid #2024YR4 will not impact Earth on the Dec 22, 2032 fly-by. An impact on the #Moon🌒 is still not ruled out. Another JWST observation is scheduled for May before the rock disappears into the dark outer solar system for several years. livescience.com/space/asteroid #astronomy #PlanetaryDefense #PlanetaryDefence #LowFlyingRocks #space

“We really shouldn’t have found a galaxy like this, given our current understanding of how the universe evolved. Imagine the early universe wrapped in a thick fog, making it extremely hard to detect strong beacons shining through it. Yet here we see this galaxy’s beam piercing through the veil.”

Since this morning, the NASA/ESA/CSA #JWST has been taking near-IR images of Sharpless 305, a star-forming region in the outer reaches of the Milky Way ✨

Below is an image taken with the ESO VLT many years ago in poor weather – the JWST images should be better 😉

When finished in a couple of hours, that'll be the last of my Guaranteed Time Observations, granted when I was selected as a member of the JWST Science Working Group in 2002 👴

It has been a privilege 🙇‍♂️

A picture of space showing a cluster of stars in the top-right corner surrounded by nebulosity, and a deeply-embedded protostar in the lower-left corner, also with nebulosity. The image has browns and purples against a black background, with horizontal streaks due to cloud and bright sources.

Herbig-Haro 49/50 (Spitzer and Webb Images Side-by-Side)

This side-by-side comparison shows a Spitzer Space Telescope Infrared Array Camera image of HH 49/50 (left) versus a Webb image of the same object (right) using the NIRCam (Near-infrared Camera) instrument and MIRI (Mid-infrared Instrument).

The Webb image shows intricate details of the heated gas and dust as the protostellar jet slams into the material. Webb also resolves the “fuzzy” object located at the tip of the outflow into a distant spiral galaxy. The Spitzer image shows 3.6-micron light in blue, the 4.5-micron in green, and the 8.0-micron in red (IRAC1, IRAC2, IRAC4). In the Webb image, blue represents light at 2.0-microns (F200W), cyan represents light at 3.3-microns (F335M), green is 4.4-microns (F444W), orange is 4.7-microns (F470N), and red is 7.7-microns (F770W).

Updated diagram version for #SciComm usage!

Have stitched together the annotated image, along with that excellent diagram from The Planetary Society.

Someone said to me last night that this looks like a half-cut avocado, and now I cannot unsee it lolololol

Such a great image, and another fine example of how physics allows us to see around corners!

Three tile image with two images in top row. Top row: In the centre is an elliptical galaxy, seen as an oval-shaped glow around a small bright core. Around this is wrapped a broad band of light, appearing like a spiral galaxy stretched and warped into a ring, with bright blue lines drawn through it where the spiral arms have been stretched into circles. A few distant objects are visible around the ring on a black background. The image has been annotated to point out the foreground galaxy as well as the background spiral. In the bottom row: Diagram showing the JWST on one side with light being focused into it from a distant galaxy, via an intermediate galaxy. The Galaxy appears as a ring as light scattered in all directions is delivered to the focal point.

Wow, a stunning image by JWST of an Einstein ring, a more distant galaxy's light being bent by gravitational lensing around a much closer galaxy. The closer galaxy is an elliptical and the much more distant galaxy, which in this case is perfectly aligned behind the foreground elliptical thereby forming the ring, is a spiral galaxy. I think this beautiful image is going to be my desktop for awhile. Just stunning!
