Scientists predict one of the major surveys by NASA’s upcoming Nancy Grace Roman Space Telescope may reveal around 100,000 celestial blasts, ranging from exploding stars to feeding black holes. Roman may even find evidence of some of the universe’s first stars, which are thought to completely self-destruct without leaving any remnant behind. This simulation showcases [...]

NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute/Alex Parker This image, taken by NASA’s New Horizons spacecraft on July 14, 2015, is the most accurate natural color image of Pluto. This natural-color image results from refined calibration of data gathered by New Horizons’ color Multispectral Visible Imaging Camera (MVIC). The processing creates images that would approximate [...]
Teresa Sindelar always knew she wanted to be a part of human spaceflight, but she was unsure how to make that dream a reality until a chance encounter with former NASA astronaut Tom Stafford when she was 11 years old. The pair met in a local jewelry shop near Sindelar’s Nebraska home, where Gen. Stafford [...]
6 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s Mariner 4 captured the first-ever close-up image of Mars on July 14, 1965. While waiting for the data to be processed into the image (inset at right), team members hand-colored strips of paper that the data was printed on, assigning hues to value [...]
