Hey all, over the years I have added some really cool photos that were all taken from space and they are all mixed in somewhere, deep, deep in the abyss of the Post a Picture thread.
Some new photos of Jupiter came out today and instead of them getting lost in the abyss? I decided that we will actually have a dedicated thread for nothing but articles, photos and some of the really cool stuff that Space has to offer.

Looks like an angry planet. Very cool pictures.

Here are some of the other recent ones posted in the other thread....
The Nile River taken from the ISS.
The Horsehead Nebula.
The Sombrero galaxy m104. This galaxy is challenging to shoot and process, this image took 48hrs of exposure time total, and the final result blew me away. This might be the most detailed image of the galaxy captured from the northern hemisphere by an amateur. I should mention btw this image uses zero noise reduction or AI processing (excluding color noise reduction), it is just good quality data. This galaxy is 30 million light years away in the constellation Virgo. This was captured of course from SRO, with several nights of sub-arcsecond seeing.

I thought that Bob Ross encouraged us to make all of our planets happy little planets.

Except for Mars, right?

These pictures are amazing.
Of course they are all cgi and the earth is flat 😝- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit. -

So, these are excellent and I don't want to pollute this thread (well, at least not too much!) -- but I am a pretty down-to-earth guy, so I get my space from the ground up.
The streak of light in the image above is the ISS passing overhead.
Hmm... maybe I should start a gofundme page to buy myself a motorized equatorial mount
On the bright side
a picture like this does show 1) that the earth does turn on an axis and 2) the stars really are different colors!
-
NASA pictures are in black and white, I never looked into how they add color.
-
They may use spectral data on the light emitting objects in their images... or they might take multiple monochrome exposures through R, B, and G filters. The results can be used to regenerate a true color image. IIRC, the early Mars landers used that latter approach.
I do know on the Viking landers, they had a color wheel in at least some of the photographs. Since they knew exactly the colors on the wheel, they could recalibrate photographs from Mars to true color.
That said, I also remember -- vividly! -- the first color photos from the Martian surface, showing a beautiful blue sky. "They" walked that back pretty quickly and re-released images with the soon-to-be familiar russet/salmon sky color.
Not that I am suspicious of any funny business goin' on at the time...

They had a hell of a magnifying glass.. -
He's a great, GREAT Photographer.
Outstanding compositions!Most people just listen to music and watch movies. I EXPERIENCE them. -
No doubt! Thanks for sharing Ryan. I would love to set up camp where he did to take those photos....or here.

Those are, indeed, great images.
I love that kind of stuff.

I was walking/hitchhiking home from school around noon one day. I didn't want to wait 4 hours for the bus and it was a glorious day. A 10 to 15 mile trip/hike to get home.
Half way home, a barn about the size of this one decided to give up the ghost. It was 25ft. from the road I estimate. As I was walking beside it, the ground shook and the barn made groans from hell. Then the loud low-toned cracking and snapping happened. 15 seconds or more and it was over. The roof sat on the ground now.
The barn collapsed straight down though. Not like in the picture but it really resembled it in size and structure comparisons.
I was freaking out the whole 15+ seconds!
A hundred years or more and it's exact moment it couldn't hold it's own weight, I was walking by it.
What a coincidence!
It was soul moving for real.
The memory is still so vivid, I feel like it could've happened yesterday.Most people just listen to music and watch movies. I EXPERIENCE them. -

For those that are interested....Mark your calendar for June 24th @4:20am. For the first time in 100 years, you may get a glimpse of the unusual sky occurrence on that morning when all five planets (Mercury, Venus, Mars, Jupiter, and Saturn) and the moon will be visibly lined up simultaneously.

Also, a most interesting article about something I thought impossible - It was written/announced on December 28, 2021.....thought that this would be bigger news. This is the first I have heard of this. Looks like we need to re-write some textbooks now....

A guy who bought some stereo stuff from me mailed me this CD and another one. He saw that I was listening to relaxation music for my neck pain. It was pretty cool of him to do that.
I fell asleep to this CD more times than I can remember. Most people just listen to music and watch movies. I EXPERIENCE them. -
Here is another shot of the Sombrero galaxy, this time taken by NASA's Hubble Telescope. Pretty good detail for 30 million light years away....

This one is an interesting one. It's commonly referred to as the "Fighting Dragons of Ara". The colors may not be what you see in other captures because it completely depends on how many hours each of Hydrogen Alpha, Sulphur II and Oxygen III gases are exposed through dedicated filters.
NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there – some are only a few million years old. This spark of formation was probably caused when the last batch of stars went supernova. About 4K light years away.

My feeble brain hurts when I try to comprehend that by the time the light from some of these stars reaches us, they will no longer be there.
Or that the stars we see in tonight's sky are already long gone. Hnngghhhhhh. -
I still think when we look through a powerful telescope, we're seeing WHAT IS THERE AT THAT MOMENT.
Just a belief I have personally.
Does a photon of light travel "forever" in a straight line?
Why are stars seen as pinpoint spots of light?
Shouldn't the star's light be spread out in all directions making the light diffused?Most people just listen to music and watch movies. I EXPERIENCE them. -

Does a photon of light travel "forever" in a straight line? Light can be bent by the gravitational force of another object (such as a black hole)
Why are stars seen as pinpoint spots of light? Distance determines the size of the pinpoint and none of them are close other than our own sun.
Shouldn't the star's light be spread out in all directions making the light diffused? If space was as filthy dirty as the air in downtown LA, yes, but it's not. For the most part

Those questions touch on what's known as the "Night Sky Paradox"
https://en.wikipedia.org/wiki/Olbers'_paradox
It's actually pretty fundamental to current thinking on the expanding nature of the universe.
As to what photons do, they will travel forever at the speed of light (in whatever medium they're traveling through) until and unless something happens to them. Stuff happens to photons all the time.
The inviolable nature of c (the speed of light "in a vacuum") leads to some interesting effects all by itself. The speed of light is an upper limit, but it depends on the medium through which light passes (which is also true of the speed of sound... but I digress). The speed of light in a vacuum is different than the speed of light through glass, or water.
One very real consequence of this is the blue light seen in water tanks in certain nuclear reactors. This
glow is called Cherenkov Radiation and is a direct result of what happens when something traveling "at the speed of light" in one medium crosses a transition into another medium in which the
speed of light is lower. Something's gotta give! And something does -- the excess velocity 'bleeds off' in the form of energy -- in the case of Cherenkov Radiation, in the form of "blue light" photons.

We are. However, 'THAT MOMENT' occurred at some point in our past.

Viewed from the perspective of a light beam/photon particle, there is no time.
Has to be that way, because the speed of light is an "inviolable" constant. For example, suppose you were on a train going 75% of the speed of light in one direction. Another train moving at 75% of the speed of light passes you going the other direction. What's the speed of the other train from your observation point? 150% of the speed of light, right? Wrong-o-rama, since it can't be.
No problem -- as long as the rate of time passage decreases with increasing velocity.
At the speed of light, "It's always five o'clock" is absolutely true, not just "somewhere".
This effect (time moving slower as the speed of light is approached), known as time dilation, was nicely explained by astrophysicist Dr. Brian May, albeit in his side hustle.
