HR 8799 Image Animated With Hot Jupiters January 28, 2017Posted by stuffilikenet in Awesome, Geek Stuff, Photography, Science.
Scientists have detected thousands of exoplanets in recent years, by watching varying brightness as they occlude their stars. This animation comes from direct imaging methods (not radio telescopes), meaning that the telescopes saw the Jupiter-sized planets directly (hot Jupiters are young planets that still glow in the infrared portion of the spectrum).
Jason Wang at the University of California, Berkeley has combined several observations of HR 8799 into the delightful GIF below. This is years of optical data, folks. “In this video you’re seeing real data,” he told Gizmodo1 of the video above. “I smoothed out the orbits so that it’s as if we’re watching [the planets] constantly in real time.”
1 I stole the picture from Giz. I feel no shame at all. Follow that link, though; there’s much more!
