2021-01-17 15:00:00 UTC As you'd probably expect from the space agency, NASA has always been at the forefront of visual technology. Back in 2017, NASA astronauts Peggy Whitson and Jack Fischer live-streamed a broadcast from the International Space Station using 4K ultra-high-definition technology â the next-gen standard for video â for the first time. Using 4K makes for incredibly sharp image quality, with a horizontal screen resolution of up to 4,000 pixels (the previous 1080P high-def standard's horizontal pixel count was 1,920). The ISS' high-def 4K camera has the ability to record up to 300 frames per second â compare that to a high-end smartphone's 60 frames per second â while the Hubble Telescope's primary mirror, which is what the Telescope uses to capture space imagery and beam it back down to Earth, can collect about 40,000 times more light than the human eye. Using these technologies, plus ultra-high-definition equipment on other spacecraft, NASA has gone on to capture hours and hours of 4K footage, offering a fascinating video gallery of immersive imagery, as well as generating recreations of past events in high-definition renderings.Â
