Risks of Decompression Sickness and Venous Thromboembolism during Spaceflight and Patent Foramen Ovale ImplicationsNASA’s Office of the Chief Health and Medical Officer formed a working group in August 2026 to review the most recent data related to extravehicular activity (EVA) prebreathe testing and decompression sickness (DCS) events, venous thromboembolism (VTE) in-flight occurrences, and patent foramen ovale (PFO) implication as they relate to NASA’s Artemis (lunar and beyond) missions. The recommendations from this working group are built upon and integrate the outcomes of previous working groups hosted by OCHMO.
NASA-Funded Research Finds Complex Life Defying Record HeatLee esta historia en español aquí. NASA-supported scientists have discovered an organism that lives at extreme temperatures previously thought impossible for complex life. High temperatures can cause the destruction of necessary cell components, which is a big problem for cells with complex parts like a nucleus encasing delicate genetic information. In the heated waters of […]
NASA’s Chandra Finds Unusual Objects in Pinwheel GalaxyUsing NASA’s Chandra X-ray Observatory, researchers found mysterious objects that give off unusually low-energy X-rays but intense levels of ultraviolet radiation. One of the galaxies they studied, M101, is pictured here in this image released on Sept. 9, 2026. Astronomers suggest these newly spotted objects in other galaxies may help solve not one, but two […]

An Epic View of the SeasonsThe tilt in Earth’s axis of rotation makes the apparent position of continents shift with the seasons in imagery from a NASA camera in deep space.
Embracing the EquinoxDepending on your locale, equinoxes can be seen as harbingers of longer nights and gloomy weather, or promising beacons of nicer temperatures and more sunlight. Observing and predicting equinoxes is one of the earliest skills in humanity’s astronomical toolkit. Many ancient observatories around the world observed equinoxes along with the more pronounced solstices. These days, […]
