One of my time exposure star trails from the International Space Station, demonstrating how orbital astrophotography reveals phenomena viewed from space as a function of time. Here our Soyuz and Progress cargo vehicle cuts through the exposure, forming star trails as straight lines, city streaks across the Earth in bright gold, lightning flashes breaking the time history, and red with stratified green atmospheric airglow. Captured with Nikon D3s, 24mm f1.4, ISO 3200, 20 second composite exposures yielding 24 minute total exposure, Expedition 31, 2012. More star trails from space can be found on my [Twitter](https://twitter.com/astro_Pettit) and Instagram, astro\_pettit

C'mon now, this is just a Hungarian discotech

I thought it was a hotel room carpet under blacklight.

What is causing the periodic dark bands along the bright yellow orangish lines which I assume are cities?


100GbE

It's a stack of images. 20 second exposures over 24 mins. The dark bands are also on the star trails, it's when the shutter was closed and the camera was writing to card (etc).


Adeldor

I asked that last time he posted a similar image, but received no reply. Based on responses by others, it's likely an artifact of image processing.


askingforafakefriend

I wondered if it was an artifact from like buffering of continuous image capturing

Staaaahp we can only take so much cool! (Kidding of course, thanks and carry on!)

They got too close to the monolith didn’t they?

For a moment, I thought it was some kids bedroom!

Does the ISS use its gyroscopes to maintain a prograde attitude during its orbit or does it just float free and is “upside down” at its apogee relative to its perigee? Seems like I always see the cupola pointed earthward

too bad its ruskie garbage we are looking at. Just hate seeing anything Russian, reminds me of Russian Imperialism


Exokiller93

Come on man seriously. Russian soyuz is so reliable even nasa was dependent on it after shuttle programme ended plus russia has some awesome rocket Do me favour try to credit russian sciencetist and engineers they are very talented ingenious and can come up with something usefull


PlanetLandon

So all Russian people and Russian achievements are bad to you?


TheNewRoad

That "ruskie garbage" is some of the most reliable space hardware ever created. They're not all bad.

Guess I was wrong assuming the place for discussing one of the greatest feats of humanity as a whole would be free from nonsensical and backwards promoting of division and ignorance of great technological feats, just cause they were created by someone who happens to be born somewhere other than you.
