Colliding galaxies!
Click here and here to see full images.
Cool images from Hubble! The two photos to the right, cropped and reduced to post here, shows two different galaxies undergoing a collision with another galaxy. Both images are from of a montage of six galaxy merger images from the Hubble Space Telescope, released yesterday.
To celebrate a new year, the NASA/ESA Hubble Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy.
It is during rare merging events that galaxies undergo dramatic changes in their appearance and in their stellar content. These systems are excellent laboratories to trace the formation of star clusters under extreme physical conditions.
The first galaxy merger to the right is dubbed NGC 6052, and is located in the constellation of Hercules about 230 million light-years away. This pair of colliding galaxies, according to the caption, “were first discovered in 1784 by William Herschel and were originally classified as a single irregular galaxy because of their odd shape. However, we now know that NGC 6052 actually consists of two galaxies that are in the process of colliding.”
The second image shows two galaxies, IC 694 and NGC 3690, about 700 millions after they had completed a close pass of each other. From the caption: “As a result of this interaction, the system underwent a fierce burst of star formation. In the last fifteen years or so six supernovae have popped off in the outer reaches of the galaxy, making this system a distinguished supernova factory.”
You can see all six merger images here, though to my eye these two are the most impressive.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

“It is during rare merging events that galaxies undergo dramatic changes in their appearance and in their stellar content. ”
Well, that’s a *bit* of an understatement. The first image is a galactic train wreck. Although, if you could survive the radiation, some truly spectacular night skies. What legends and stories might be born there?
I think it’s interesting to note after reading their entire site including the mechanics/forces of two galaxies colliding and the aftermath that “dark matter” is not mentioned. Although they do go into considerable mount of evidence for the interaction of gravity. (both galaxies, as they come close, are elongated and stretched out in a consistent and predictable way using only gravity as a model)
I am enjoying it while I can, the Galaxy model needs dark matter… The uncertainty of what we know and what is possible mixing fantasy/Science fiction with reality so “politics” can have a foothold in everything we are certain of, so that it only becomes a belief. Faith in a belief can be molded into any form they desire for a particular outcome regardless of the truth or facts.
Why?
Can you imagine how much money would be involved in grants from the government to find what doesn’t exist? Like “hot fusion” temperatures exceeding millions of degrees inside containers that melt at 10,000° with super cold magnets inches away… Like what is going to occur to us shortly with the “green new deal” claming carbon dioxide, the source of all life on planet earth, is pollution? That everyone must be vaccinated to sterilize the population? That all farms must be heavily regulated eliminating meat because food is bad for you? That all homes, businesses, high-rise buildings must be torn down and rebuilt to save energy?
I’m going to enjoy this moment before the nonsense of the dark age begins…
