They&#8217;re often scientists, engineers, or pilots. And in the case of NASA astronaut Don Pettit, he&#8217;s also an astrophotographer.<\/p>\n<p>Pettit is currently on his third stay on the <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.space.com\/16748-international-space-station.html\" data-before-rewrite-localise=\"https:\/\/www.space.com\/16748-international-space-station.html\">International Space Station<\/a> (ISS), and he&#8217;s continuing his long-running tradition of taking <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.space.com\/space-exploration\/international-space-station\/nasa-astronaut-captures-city-lights-streaking-below-iss-in-stunning-new-photos\" data-before-rewrite-localise=\"https:\/\/www.space.com\/space-exploration\/international-space-station\/nasa-astronaut-captures-city-lights-streaking-below-iss-in-stunning-new-photos\">out-of-this-world photos<\/a> (pun intended). His latest shot, an image of the stars and several <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.space.com\/15680-galaxies.html\" data-before-rewrite-localise=\"https:\/\/www.space.com\/15680-galaxies.html\">galaxies<\/a>, showcases not only his visual prowess, but also his engineering skills \u2014 he used a self-designed tool to accomplish this photo.<\/p>\n<aside class=\"hawk-nest\" data-block-type=\"embed\" data-render-type=\"fte\" data-skip=\"dealsy\" data-widget-type=\"seasonal\"\/>\n<p>At first glance, the image might look like a rather typical shot from the ISS: You see <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.space.com\/57-stars-formation-classification-and-constellations.html\" data-before-rewrite-localise=\"https:\/\/www.space.com\/57-stars-formation-classification-and-constellations.html\">stars<\/a> and the curvature of <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.space.com\/54-earth-history-composition-and-atmosphere.html\" data-before-rewrite-localise=\"https:\/\/www.space.com\/54-earth-history-composition-and-atmosphere.html\">Earth<\/a>, with a distinct orange glow above our planet&#8217;s surface. But there&#8217;s something strange about the photo: The surface of Earth is blurred, yet hundreds if not thousands of stars are in perfect focus.<\/p>\n<p>Under normal circumstances, long-exposure photographs such as this should show the stars as streaks across the sky, since the ISS is moving at about 17,500 miles per hour (28,000 km per hour).<\/p>\n<p>But therein lies Pettit&#8217;s genius. He&#8217;s brought with him to space a homemade <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.space.com\/best-star-trackers-for-astrophotography\" data-before-rewrite-localise=\"https:\/\/www.space.com\/best-star-trackers-for-astrophotography\">star tracker<\/a>, a device that rotates a camera to compensate for the ISS&#8217;s movement. It&#8217;s a variation on a tool used by <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.space.com\/astrophotography-for-beginners-guide\" data-before-rewrite-localise=\"https:\/\/www.space.com\/astrophotography-for-beginners-guide\">astrophotographers<\/a> on Earth to take long exposures of the stars as the planet rotates beneath the night sky, compensating for that rotation to keep the stars from becoming streaks in the image.<\/p>\n<p>&#8220;This tracker rotates at 90 min [sic] period to match the pitch rate of ISS. Without this tracker, you can not take photo longer than 1\/2 sec [sic] without star blur due to the rate of orbital motion,&#8221; <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.reddit.com\/r\/astrophotography\/comments\/1h9dovl\/comment\/m1024vl\/\" target=\"_blank\" data-url=\"https:\/\/www.reddit.com\/r\/astrophotography\/comments\/1h9dovl\/comment\/m1024vl\/\" referrerpolicy=\"no-referrer-when-downgrade\" data-hl-processed=\"none\" rel=\"noopener\">wrote Pettit on Reddit<\/a>.<\/p>\n<p>The result is an unbelievably clear image of the night sky, showing vastly more stars than is possible with a shorter exposure.
