Webb takes an infrared look at the mane of the Horsehead Nebula

The cool infrared image to the right, cropped, reduced, and sharpened to post here, was taken by the Webb Space Telescope and released today. The three pictures above provide the context, with the rectangle inside the rightmost image indicated the area covered by the close-up to the right.
Webb’s new images show part of the sky in the constellation Orion (The Hunter), in the western side of a dense region known as the Orion B molecular cloud. Rising from turbulent waves of dust and gas is the Horsehead Nebula, otherwise known as Barnard 33, which resides roughly 1,300 light-years away.
The nebula formed from a collapsing interstellar cloud of material, and glows because it is illuminated by a nearby hot star. The gas clouds surrounding the Horsehead have already dissipated, but the jutting pillar is made of thick clumps of material and therefore is harder to erode. Astronomers estimate that the Horsehead has about five million years left before it too disintegrates. Webb’s new view focuses on the illuminated edge of the top of the nebula’s distinctive dust and gas structure.
In the close-up, note the many distant tiny galaxies, both above the mane as well as glowing throught it.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Humbling beauty, especially upon the realization that many of the “stars” are not stars at all but are, in fact, galaxies.
Just humbling!
I recently saw the Webb Telescope documentary “Deep Sky” in IMAX. It was good. But it lacked faith that its depiction of astronomical wonders would sufficiently move the audience. When I see a deep sky depiction of the universe from the Webb that has stars moving in the foreground, like Star Trek, I would like to ask if those are real stars or just CGI inserts? Are their positions correct? Could you name those stars if required?
I don’t know. I bet not. But I don’t know. The reality of what we are accomplishing as a species at the L2 point is not interesting enough for modern audiences so it needs CGI to augment it.
At least Behind the Black lets the wonders speak for themselves.
