Readers! A November fund-raising drive!

 

It is unfortunately time for another November fund-raising campaign to support my work here at Behind the Black. I really dislike doing these, but 2025 is so far turning out to be a very poor year for donations and subscriptions, the worst since 2020. I very much need your support for this webpage to survive.

 

And I think I provide real value. Fifteen years ago I said SLS was garbage and should be cancelled. Almost a decade ago I said Orion was a lie and a bad idea. As early as 1998, long before almost anyone else, I predicted in my first book, Genesis: The Story of Apollo 8, that private enterprise and freedom would conquer the solar system, not government. Very early in the COVID panic and continuing throughout I noted that every policy put forth by the government (masks, social distancing, lockdowns, jab mandates) was wrong, misguided, and did more harm than good. In planetary science, while everyone else in the media still thinks Mars has no water, I have been reporting the real results from the orbiters now for more than five years, that Mars is in fact a planet largely covered with ice.

 

I could continue with numerous other examples. If you want to know what others will discover a decade hence, read what I write here at Behind the Black. And if you read my most recent book, Conscious Choice, you will find out what is going to happen in space in the next century.

 

 

This last claim might sound like hubris on my part, but I base it on my overall track record.

 

So please consider donating or subscribing to Behind the Black, either by giving a one-time contribution or a regular subscription. I could really use the support at this time. There are five ways of doing so:

 

1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.

 

2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation. Takes about a 10% cut.
 

3. A Paypal Donation or subscription, which takes about a 15% cut:

 

4. Donate by check. I get whatever you donate. Make the check payable to Robert Zimmerman and mail it to

Astronomers discover a well-developed spiral galaxy too soon after the Big Bang

The early spiral galaxy
Click for original image.

Using the Webb Space Telescope, astronomers have discovered the earliest known well-developed spiral galaxy, dubbed Zhúlóng (meaning torch dragon in Chinese), that exists only about one billion years after the Big Bang and much too soon for such a spiral galaxy to have formed.

The false-color infrared Webb image to the right, cropped to post here, shows clearly the galaxy’s spiral structure.

Zhúlóng has a surprisingly mature structure that is unique among distant galaxies, which are typically clumpy and irregular. It resembles galaxies found in the nearby Universe and has a mass and size similar to those of the Milky Way. Its structure shows a compact bulge in the center with old stars, surrounded by a large disk of younger stars that concentrate in spiral arms.

This is a surprising discovery on several fronts. First, it shows that mature galaxies that resemble those in our neighborhood can develop much earlier in the Universe than was previously thought possible. Second, it has long been theorized that spiral arms in galaxies take many billions of years to form, but this galaxy demonstrates that spiral arms can also develop on shorter timescales. There is no other galaxy like Zhúlóng that astronomers know of during this early era of the Universe.

You can read the peer-review research paper here. The scientists posit a number of theories to explain this spiral galaxy, none of which have much merit at this time because so little data exists from that time period. That only one such spiral galaxy is presently known does not mean such galaxies were rare at that time. It merely means our census of galaxy populations in the early universe remains woefully incomplete.

Genesis cover

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 print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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

    “ dubbed Zhúlóng”

    The political correctness makes my teeth hurt. If the Chinese want to name discoveries, they can put up their own telescopes.

    again, timescape theory predicts this

    the galaxy is probably a few billion years old, rather than one billion

    timescape says observers in voids experience ~30% faster passage of time

    the upshot is that our distance/time measurements based on the flat FLRW equations need to be adjusted for inhomogeneities

    these adjustments were small enough in the pre-Webb era that they could not be distinguished from LCDM

    but at high redshift the oddities start to crop up in galaxies that appear mature right after reionization, with oxygen and mature formations

    last year the PANTHEON database provided a pretty good fit to timescape predictions… the Euclid results are sufficiently detailed to either rule it out or make timescape the new standard model, hopefully within the next year or two (QR1 might not be enough but the first full release is 30x larger)

    Yeah, when did they start naming galaxies with chinese-communist names?
