An international team of astronomers has uncovered new evidence to explain how pulsing remnants of exploded stars interact with surrounding matter deep in the cosmos, using observations from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) and other telescopes. Scientists based in the U.S., Italy, and Spain, set their sights on a mysterious cosmic duo called PSR J1023+0038, […]
Two Stars in Solar Science It takes a lot of work to make space missions happen. Hundreds or even thousands of experts work as a team to put together the spacecraft. Then it has to be tested in conditions similar to space, to be sure that it can survive out there once it is launched. […]
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. Cosmic explosions offer […]
The NASA-supported fourth private astronaut mission to the International Space Station, Axiom Mission 4, completed its flight as part of the agency’s efforts to demonstrate demand and build operational knowledge for future commercial space stations. The four-person crew safely returned to Earth, splashing down off the coast of California at 5:31 a.m. EDT on Tuesday, […]

Written by Ashley Stroupe, Mission Operations Engineer at NASA’s Jet Propulsion Laboratory Earth planning date: Wednesday, July 9, 2025 In today’s plan, we have a little bit of everything. With it being winter still, we are taking advantage of the ability to let the rover sleep in, doing most of the activities in the afternoon […]

Seasonal snow plays a significant role in global water and energy cycles, and billions of people worldwide rely on snowmelt for water resources needs, including water supply, hydropower, agriculture, and more. Monitoring snow water equivalent (SWE) is critical for supporting these applications and for mitigating damages caused by snowmelt flooding, avalanches, and other snow-related disasters. […]
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 the colors that the human eye would perceive, bringing […]
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 […]
