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.
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

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.

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.
