Jets from baby stars
Click for full image.
Cool image time! The picture to the right, rotated and reduced to post here, was taken across multiple wavelengths by the Hubble Space Telescope and shows two different Herbig–Haro objects (HH 1 at the top and HH 2 on the bottom). Herbig-Haro objects are the bright cloud clumps found near newly formed baby stars. These particular clouds are about 1,250 light years away. The jets flowing away from HH 1 are speeding away at about 250 miles per second.
Note that the baby stars themselves are not visible, buried in the dust that surrounds them. The bright star in the upper right is an unrelated foreground star.
In the case of HH 1/2, two groups of astronomers requested Hubble observations for two different studies. The first delved into the structure and motion of the Herbig–Haro objects visible in this image, giving astronomers a better understanding of the physical processes occurring when outflows from young stars collide with surrounding gas and dust. The second study instead investigated the outflows themselves to lay the groundwork for future observations with the NASA/ESA/CSA James Webb Space Telescope. Webb, with its ability to peer past the clouds of dust enveloping young stars, will revolutionise the study of outflows from young stars.
There is a lot of complexity here that this image only hints at. Note for example the smaller cloud objects near HH1, the shape of which suggest a shaping by some interstellar wind.

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.
All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

Again, an absurd although beautiful picture.
That is where we come from.
And just like everyone who will read this will someday die so will our sun and our planet “Die” and be no more.
What does that make us all?
“What does that make us all?”
‘Dust, Dust in the Wind
All We are is Dust in the Wind.’
Blair:
You aren’t wrong: https://youtu.be/tH2w6Oxx0kQ
But there is a logic break that occurs when you attempt to rationalize the dust with the flesh and blood observation of the dust and attempting to understand how the one becomes the other.
And now we are on a whole nother subject.
Human beings must have answers to questions.
But some questions human beings may not have the capacity to answer.
Just like a cat chasing a red laser spot or a gorilla unexpectedly running into a mirror in the jungle.
Cat V laser: https://youtu.be/Vo4yZ_bM8io
Gorilla V Mirror: https://youtu.be/tz0avWZoqjg
They just do not have the capacity to understand. Is that in fact the condition we find ourselves in in our “advanced” state?
We cannot even understand and explain what this is and where it comes from: https://youtu.be/rO_M0hLlJ-Q
Things may not be what we think they are.
250 miles per second is 8,000,000,000 miles per year (rounded). A light year is 6,000,000,000,000 miles (rounded). So (super rounding), that’s about 1/1000th of a light year per year and it’s about 1000 light years away. Math shown for corrections.
Can we detect that movement? How big is a pixel at that distance in that image?
This might be a place where the ridiculous “parsec” unit becomes useful, since the size of a pixel depends on distance.
BTW: “google it” is not a bad answer to that question, but google what?. “Size of pixel from Hubble at 1000 light years” is not helpful.
