Astronaut Captures Stunning Galaxy Views from ISS with Homemade Star Tracker

NASA astronaut Don Pettit, currently aboard the International Space Station, has captured a stunning deep space photograph using a homemade star tracker. This device compensates for the ISS's rapid movement, allowing for long-exposure shots that keep stars in perfect focus while the Earth's surface appears blurred. Pettit's ingenuity in creating this tool highlights his engineering prowess, similar to his previous invention of a zero-G coffee cup. The star tracker enables the capture of vastly more stars than typical short-exposure images.
