1 00:00:00,000 --> 00:00:00,600 [Music throughout] 2 00:00:00,600 --> 00:00:04,270 This groundbreaking detector isn't measured in megapixels. 3 00:00:04,270 --> 00:00:07,540 It's a six-by-six grid of 36 pixels, 4 00:00:07,540 --> 00:00:11,144 but they're unlike any others. 5 00:00:11,511 --> 00:00:13,813 Although this detector, called Resolve, 6 00:00:13,813 --> 00:00:16,383 can create low-resolution X-ray images, 7 00:00:16,483 --> 00:00:19,052 that is not what makes it unique. 8 00:00:19,052 --> 00:00:22,489 Each pixel in Resolve can measure tiny amounts of heat. 9 00:00:22,722 --> 00:00:26,292 This allows Resolve to measure how much a pixel warms 10 00:00:26,292 --> 00:00:28,461 when it absorbs a single X-ray, 11 00:00:29,229 --> 00:00:30,230 As a result, 12 00:00:30,563 --> 00:00:33,833 our newest X-ray telescope in space, XRISM, 13 00:00:34,300 --> 00:00:37,237 can create the most detailed X-ray spectrum ever 14 00:00:37,237 --> 00:00:38,772 for distant objects. 15 00:00:39,272 --> 00:00:41,474 This would be a revolutionary achievement 16 00:00:41,474 --> 00:00:43,743 for a detector with a single pixel. 17 00:00:43,977 --> 00:00:46,046 But Resolve has 36. 18 00:00:46,579 --> 00:00:48,181 The Resolve detector on XRISM 19 00:00:48,181 --> 00:00:50,016 will be revolutionizing our understanding 20 00:00:50,216 --> 00:00:51,818 of the large-scale, 21 00:00:51,818 --> 00:00:53,119 high-energy universe. 22 00:00:53,553 --> 00:00:54,921 And that’s pretty amazing 23 00:00:54,921 --> 00:00:57,590 for a “mere” three dozen pixels. 24 00:01:19,345 --> 00:01:21,981 and built at NASA’s Goddard Space Flight Center. 25 00:01:22,615 --> 00:01:24,551 The detector’s success in XRISM 26 00:01:24,784 --> 00:01:27,120 will enable Goddard to further the design 27 00:01:27,120 --> 00:01:30,056 an follow up with X-ray microcalorimeters 28 00:01:30,123 --> 00:01:33,059 with hundreds or even thousands of pixels. 29 00:01:33,860 --> 00:01:37,397 So, while it may not sound as impressive as 4k 30 00:01:37,397 --> 00:01:39,332 or 50 megapixels, 31 00:01:39,332 --> 00:01:41,167 the Resolve detector on XRISM 32 00:01:51,578 --> 00:01:56,449 [NASA] |
