This wide-field image shows a stretch of the Milky Way visible from the Southern Hemisphere. At center is Crux (The Southern Cross). The bright yellow-white star at far left is Alpha Centauri, which is actually a three-star system. Material ejected from this system could make (or have made) its way by our solar system.Akira Fujii […]
NASA, in partnership with AeroVironment and Aerostar, recently demonstrated a first-of-its-kind air traffic management concept that could pave the way for aircraft to safely operate at higher altitudes. This work seeks to open the door for increased internet coverage, improved disaster response, expanded scientific missions, and even supersonic flight. The concept is referred to as […]
The fifth anniversary of the first all-female spacewalk by NASA astronauts Christina H. Koch and Jessica U. Meir seems like a good time to tell the story of women spacewalkers. Since the first woman stepped outside a spacecraft in 1984, 23 women from four nationalities have participated in 61 spacewalks. These women made significant contributions […]
NASA selected a crew of four research volunteers to participate in its last simulated mission to Mars in 2024 within a habitat at the agency’s Johnson Space Center in Houston. Obaid Alsuwaidi, Kristen Magas, Tiffany Snyder, and Anderson Wilder will step into the 650-square-foot HERA (Human Exploration Research Analog) facility on Friday, Nov. 1. Once […]
This NASA/ESA Hubble Space Telescope image features the striking spiral galaxy Messier 90 (M90, also NGC 4569), located in the constellation Virgo. In 2019, Hubble released an image of M90 created with Wide Field and Planetary Camera 2 (WFPC2) data taken in 1994, soon after its installation. That WFPC2 image has a distinctive stair-step pattern […]

Have you seen comet Tsuchinshan-ATLAS yet? If you’ve not been able to glimpse the bright, icy space rock that’s traveled from the edge of the solar system, it’s not too late. But you need to see it soon. The coma and long tail of comet Tsuchinshan-ATLAS, also called C/2023 A3 (Tsuchinshan–ATLAS), is currently shining at […]
NASA’s Space Biology Program within the agency’s Biological and Physical Sciences division conducts research across a wide spectrum of biological organization and model systems to probe underlying mechanisms by which organisms acclimate to stressors encountered during space exploration (including microgravity, ionizing radiation, and elevated concentrations of carbon dioxide). This research informs how biological systems regulate […]

On October 3rd, NASA’s Solar Dynamics Observatory captured this image of the most powerful flare yet of Solar Cycle 25. The flash of light was classified as X9.0; the most powerful flare on record occurred during the last solar maximum, in 2003, and was classified as X45.NASA A panel of scientists from NASA and the […]
