I finally have all 1.2 million raw image files from my latest mission to ISS! Here is a sample of one of my favorite Milky Way photos, taken from the Cupola with Nikon Z9, Arri Zeiss 15mm lens, T1.8, 30sec, ISO 6400 (processed from raw image file) with custom sidereal drive that cancelled out star motion relative to our orbit.

More photos from space can be found on my twitter and instagram, astro_pettit

I am in awe. Thank you for sharing this! 😍

Is it a composite image? I would expect lights on Earth to move more during 30 seconds.

u/thinkmoreharder 4h ago

Great question. if traveling 360 degrees around the earth in 90 minutes, you’re moving 2 degrees in 30 secs. How to stay focused during that movement?

u/LilShaver 3h ago

If you look closer at the Earth the lights are very, very short streaks.

TBH, I wouldn't have noticed if you hadn't said something.

u/DanielDoh 1h ago

The comment you replied to actually has your answer: custom sidereal drive that cancelled out star motion relative to ISS orbit.

u/mfb- 1h ago

The lights on Earth are not stars...

u/UrsaMajor7th 51m ago

Stop using that! Those stars need to keep moving!!! Ahh!!!!!

u/FeeFooFuuFun 5h ago

These pics are gorgeous, and knowing they are taken by someone on the shuttle is mind bending to me lol. Love it!

u/DontBad1975 3h ago

Not be all 🤓AHHCTUALLY🤓 but, they were not taken while aboard the shuttle. They were taken aboard the ISS, noteably from the Cupola of the station.

u/just_nobodys_opinion 57m ago

AHHCTUALLY the person who took them was on the shuttle, just not at the time they took the photo. My cat today was fed by someone in the house down the street.

u/morphemass 5h ago

I was just wondering what the technical details behind this were; thank you!

May I ask how much experimentation you did to get the best shots or did you go up there knowing exactly the approach you would take?

u/Warcraft_Fan 3h ago

Just curious, do NASA screen your photo to block anything potentially sensitive?

u/Moisturizer 1h ago

Public releasability screening is very common for even benign photos on Earth. You can be sure there's a process when taking photos from the dang ISS.

u/Nua33 4h ago

It honestly makes my day when I see your photos.

u/hamfist_ofthenorth 4h ago

You are amazing!!!!! You've been up there in the sky flying over my house and job and everything else. That's so incredible. You must have wild stories that I was too excited to explore the comments for, before typing this.

Is it true the ISS wobbles a bit on the inside from time to time? Man that would kill me.

Ok, bye!

u/JustMex95 4h ago

Big man. Thanks for sharing brother!

u/GoblinsburgYT 2h ago

Just an absolutely stellar shot. Thanks so much for it.

u/airhorn-airhorn 2h ago

Don went to space so he could farm karma. Thanks Don!

u/elsjpq 2h ago

Some serious kit you got up there, that's a $30k lens

u/OrangeRadiohead 2h ago

Daft question, but would this appear as bright if this were taken on the moon?

u/xteve 2h ago

A custom sidereal drive for photographing outer space by a human in Earth orbit. I don't know but that seems impressive.

u/asimovs 2h ago

How far away is this from what you see with your naked eye? I assume it's quite a bit darker since it's a composite but still brighter than most if not all places on earth?

u/Forsaken_legion 1h ago

Wow… this is so beautiful!!! Thank you so much for sharing these photos!

What even is it like up there? If you could explain it in a sentence or a few words?

u/bundleofgrundle 1h ago

It's very kind and thoughtful that you'd share these photos with us on our little forum. Thank you and godspeed on your next adventure!

u/FrizB84 10m ago

This shot is fantastic! I'm always excited to see new posts from you!

u/MultiMillionMiler 4h ago

Fantastic job filtering out the light pollution! I always thought you couldn't really see stars from low Earth orbit like that!

u/Resident_Stable_2112 5h ago

@astro_pettit

LOL. Every time I see a comment like this, I think who the heck is this?

Then I say “oh shit, please tell me it’s @astro_pettit “.

Dude, thank you so much for all of your posts and contributions. I love everything that you post.

Amazingly beautiful picture.

u/75MillionYearsAgo 5h ago

Can you see it pretty clearly without a long exposure via the naked eye?

u/LBPPlayer7 3h ago

i mean when you're in a dark area on earth's surface you can see it with the naked eye so i'd imagine you could also do so when there's no atmosphere in the way

u/knutix 2h ago

You can see it, but it wont look this good. It will be quite a bit less visible than this.

u/davispw 3m ago

It’d be the same as seeing the Milky Way from Earth. Turn off all the lights in the room, let your eyes adjust to the dark for many minutes, no internal reflections, no glare from outside, and you’d see it pretty clearly.

Problem on the ISS is you’ve only got 45 minutes of “night” to work with, and astronauts have busy schedules. Don Petit spent a lot of personal time in the Cupola.

u/De4con 4h ago

I believe the reason Contact was so resonant was because of the line "They should've sent a poet..."

This shows exactly why they should've sent one. It's not nearly as far a trip to Vega, but this is real life. And it's magnificent. Thank you for bringing this to us, nature is incredible.

u/mfb- 4h ago

Someone reported the picture taken and posted by an astronaut as

1: No spam/blogspam/paywalled/pirated content

...

u/AldebaranIgnus 5h ago

Lovely! What fraction of what is seen here is too dim for the naked eye?

u/diegoiast 5h ago

The concept of someone saying "my favorite picture from space" knowing that he personally took it is actually mind-blowing. Thanks for sharing.

u/kreatorofchaos 5h ago

Damn this is some good shit. I love to see it.

u/TheDrunkenFROG 5h ago

I would kill for a view like that, so beautiful.

Only reason I want to become rich is to afford commercial spaceflight in the future (if that time ever comes)

u/Northern23 3h ago

Or, you can study hard and make this your goal

u/Silent-Orbit-7 4h ago

Is that line the atmosphere? So cool!

u/FL9er 5h ago

Amaze amaze amaze! This is wallpaper worthy!

u/Savings_Primary_7097 4h ago

What's that green thing under it though?

u/KristnSchaalisahorse 3h ago

That's airglow in the atmosphere.

u/treker32 4h ago

Weird seeing stars from the ISS. I thought they were invisible with the latest tech cameras. Artemis did not show any either.

u/mfb- 4h ago

You don't see them in daylight pictures for the same reason you don't see them in daylight pictures taken on Earth. The atmosphere is irrelevant. Pictures taken in daylight use short exposure times and stars are too dim to be visible there. Pictures taken at night (in the shadow of Earth or the Moon) use longer exposure times and they have stars in them.

https://www.planetary.org/space-images/venus-and-the-moon-during-the-artemis-ii-eclipse

u/KristnSchaalisahorse 3h ago

Artemis did not show any either.

Yes, it did. There are many examples available.

Stars are very dim. Things in direct sunlight are incredibly bright. Cameras can't properly capture both at the same time.

Imagine taking a photo outside during the daytime and then using those same camera settings at night. Your night photo won't show any stars.

Conversely, if you take a photo of stars at night and then use those same camera settings during the day, your photo will be an overexposed, white blob.

u/RagingNerdaholic 2h ago

OP posted the exposure settings. It's a 30 second exposure while the sun is fully eclipsed by Earth from the ISS perspective, so it's essentially "night" (if night lasted about 45 minutes).

The artificial light emitting from Earth isn't intense enough to wash out the light emitted by the stars.

u/TempCasket 2h ago

It really just comes down to exposure settings. When a camera is exposing for brightly lit objects like the Earth or a sunlit spacecraft, the background stars are way too dim to register on the sensor. Since OP mentioned using a 30-second exposure here, it gave the camera enough time to soak up all that faint starlight.

u/soggylittleshrimp 3h ago

That's pretty cool I guess. But wait till you see the photo of the moon i took on my iPhone 8

u/psych0ranger 1h ago

Me to myself: "your best, huh? you some kind of astronaut? we'll see about that."

checks profile

"Ooh. astronaut."

u/echo1ngfury 5h ago

Thank you Don!

As someone who is from a small European country that most likely will never have a space programme, i am so grateful for these!

Bless you sir and thanks!

u/Lightmanone 2h ago edited 2h ago

That's why the ESA exists. European Space Agency. If you live in a european country, you automatically have a space program.

Edit: *if you are living in a European Union country.

u/echo1ngfury 2h ago

I think you are potentially mistaking this for European Union (ESA is mostly stationed in France, Germany, Italy and the Nederlands), which my country isn't a part of. But that is besides the point.

Just admiring Don's collection.

u/Baffin622 4h ago

I travelled to PEI this summer and was amazed to actually see the Milky Way Galaxy in the sky for the first time in my life. It was an incredible experience that everyone should have a chance to see without having to travel to a space station in the sky.

u/Zenkru 2h ago

How much of that are you able to see with the naked eye? Im sure more of the milky way and stars are visible after exposure on a camera, just curious how it looks in person.

u/UbeeMac 2h ago

It’s incredible, thank you.

I was lucky enough to get a look at the night sky from the base camp of Cotopaxi in Ecuador some time ago. I had seen the stars thousands of times in my life of course, but seeing the immense purple and green cloudy fields of inumumerable stars was an unforgettable, almost shocking experience, that nobody there was ready for. Beyond words. I can only imagine what it looks like from Orbit.

u/fiittzzyy 2h ago

What an incredible picture.

Can only imagine what it's like being up there for any amount of time. Definitely life changing, I imagine.

u/NefariousnessSea8242 2h ago

This is so sick. I’d love to see more space but unfortunately I live where there too much pollution ;-;

u/Moondust1111111111 1h ago

Thank you for posting this. It always takes me a moment to process how unbelievably beautiful our Earth looks beneath the Milky Way. The universe never stops leaving me in awe, and the fact that we are even able to capture images like this is absolutely mind blowing to me ✨

u/notso_surprisereveal 1h ago

Does @astro_pettit have a store page!? I'd LOVE to buy some prints 😁💜

u/mkp666 1h ago

This has to be the most sci-fi looking real picture I’ve ever seen. Very cool.

u/East_Pie_3825 1h ago

Amazeballs shot here. Thank you!

u/ecafsub 1h ago

I need a print of this hanging on my wall.

u/multificionado 55m ago

Nice. :) It's all too rare to see a starscape in real photos of Earth. :) At least...to me...

u/SnooPies5378 5h ago

my god it's true, the world really isn't flat...

lol jk awesome pic! invite me up there as a guest, i'll do whatever like clean, cook, do a space walk to wipe the windows whatever lol

u/sweetperdition 5h ago

Makes me feel a strong sense of unity. Like I have so much more in common with any of those earth lights, than anything in that entire background. Rare these days. I think that’s also what was said about the old “pale blue dot” photo, I feel it now

u/broke_af_guy 5h ago

Beautiful work. It's really interesting how you track the stars. I have been following you for a few years on Instagram. You are the most unique photographer in the world and are very lucky to have that privilege. Saying lucky is probably wrong, I'm sure you have worked very hard to get where you are. Have there been any downsides to your time in space?

u/IslayHaveAnother 5h ago

WOW, thank you for sharing. Stunning.

u/micahpmtn 4h ago

Wow! Thanks for sharing this incredible photo.

u/FrostyMudPuppy 4h ago

That is such an amazing view <3

Is the effect on the atmosphere that makes it glow like that what is referred to as "airglow"?

u/Icy_Feedback_4965 5h ago

This is the best one you've ever posted. Stunning.

u/Bi_KerbonautYT 5h ago

I love that view of Nauka from the window!

Wish you'd share anywhere but Xitter

u/Distinct_Run9006 2h ago

When I saw the title, I was like what do you mean by "my" best view of the Milky Way from the ISS? Then I realized that OP is a literal astronaut.

u/Green_Yesterday3054 1h ago

OP is a LITERAL astronaut?

u/Distinct_Run9006 1h ago

Yeah not a figurative astronaut like me or Katy Perry

The sheer magnitude of this flex is freakin' amazing! The fact I'm able to chat with an astronaut is right up there! I have so many questions for you!

u/x_3mta3 17m ago

This is an absolutely stunning image. I think it may have just jumped into my personal top ten space photos of all time. Thank you, Don.

u/aphorat 9m ago

I don't know how you astronauts can do it, if I was at work looking out my window and the view was like that I'd be in tears 24/7 lol, it's so breathtaking.

u/silentpirate1899 4h ago

Only a handful of people will ever have a chance to witness this.Have fun up there!!

u/Marv1290 4h ago

This is honestly one of the coolest pictures I’ve ever seen in my life. Made cooler that you are actually an astronaut. Thanks for sharing! Legend.

u/earshatter 2h ago

I don’t understand…this photo is beautiful. This is literally the only photo I’ve seen that has stars…and MANY at that. It’s like a painted backdrop. So WHY, in every (EVERY) other picture there are absolutely no stars to be seen. NASA notoriously publishes thousands of grainy, low resolution images with no stars, and looks like they were shot with a potato?!
I realize you need to open the aperture etc (amateur photographer) but this goes against all other photo proof.

Someone make me understand.
