Photographer and energetic NASA astronaut Don Pettit has captured an extended publicity photograph of two satellite tv for pc galaxies that neighbor the Milky Way from his vantage spot onboard the International Space Station (ISS).
The Large Magellanic Cloud and Small Magellanic Cloud are some 200,000 light-years away however orbit the Milky Way Galaxy, residence to Earth’s photo voltaic system.
To seize the photographs, Pettit introduced a home made monitoring system that permits him to take long-exposure images. The ISS strikes at 17,500 miles per hour, which means a monitoring system is required to lock onto a celestial goal.
During his first mission to the ISS in 2002, Pettit invented a barn door tracker from “stuff laying round” which is a tool that counteracts orbital movement in area permitting photographers to seize sharp photographs of cities at evening.
“Before I made this barn door tracker on the station you’ll do a handheld image of cities at evening with perhaps a one-second publicity they usually’d at all times be blurry significantly in the event that they have been accomplished with a telephoto lens,” Pettit advised PetaPixel in an interview final yr. “This was the primary time it allowed anyone to get sharp photographs of cities at evening.”
Capturing neighboring galaxies isn’t the one epic area shot Pettit has been taking. On December 3, he shared a star path photograph on his X web page.
“I believe these [star trail photos] are a mix of each science and artwork,” he writes on the platform previously often called Twitter.
“This one reveals atmospheric airglow, yellow-green at 120km and the fainter higher pink at 400km, star trails shifting in arcs on the left and straight strains on the proper, Starlink satellites flashing daylight off their photo voltaic panel, the Cygnus cargo automobile (left), my Soyuz automobile (heart), and the Russian laboratory module MLM (proper).”
Pettit additionally captured a novel view of Starlink satellites orbiting Earth as they flash daylight towards the ISS, a picture that may solely be captured in an orbital surroundings.

Pettit, 68, is the second-oldest NASA astronaut to ever go into orbit and is the area company’s oldest energetic astronaut.
