This pair of images shows stars observed Feb. 6, 2026, by the SPARCS space telescope simultaneously in the near-ultraviolet, left, and far-ultraviolet, right. The fact that one star is seen in the far-UV while multiple are seen in near-UV offers insights into the temperatures of these stars, with the one visible in both colors being [...]
Two powerful instruments of the NASA/ESA/CSA James Webb Space Telescope joined forces to create this scenic galaxy view. This spiral galaxy is named NGC 5134, and it’s located 65 million light-years away in the constellation Virgo.ESA/Webb, NASA & CSA, A. Leroy Stars peek through the dusty, winding arms of NGC 5134, a spiral galaxy located [...]
1 min read Help Galaxy Zoo: Tidal Tales Open Cosmic Storybook Galaxies carry the imprints of past encounters. When they pass near one another or collide, gravity pulls their stars into long tails, thin streams, and faint shells – features that preserve the history of these dramatic events. Thanks to deep, high-resolution images from [...]
Download PDF: Efficient Large Displacement/Large Rotation Dynamic Simulations Using Nonlinear Dynamic Substructures Utilizing reduced-order dynamic math models (DMM) in linear system-level dynamic analyses is a well-known practice that enables extreme computational efficiencies. But what about nonlinear system dynamics? Reduced-order DMMs have found their way into contact dynamics. The engineer must look no further than the [...]
The Cygnus XL cargo spacecraft, with its prominent cymbal-shaped UltraFlex solar arrays, departs the International Space Station after its release from the Canadarm2 robotic arm.NASA+ At 7:06 a.m. EDT, Northrop Grumman’s Cygnus XL was released from the Canadarm2 robotic arm, which earlier detached the cargo spacecraft from the Earth-facing port of the International Space Station’s [...]
Northrop Grumman’s Cygnus XL cargo craft is pictured in the grips of the Canadarm2 robotic arm following its capture on Sept. 18, 2025. Cygnus XL is Northrop Grumman’s expanded version of its previous Cygnus cargo craft increasing its payload capacity and pressurized cargo volume.NASA Live coverage of the departure of Northrop Grumman’s Cygnus XL cargo [...]
Photo of the Day Is this a cosmic monster ready to devour an unsuspecting galaxy? Thankfully, that is not the case. The red “monster” shown in the featured image is Cometary Globule CG 4, 1,300 light-years away in the Constellation Puppis. CG 4 is a molecular cloud, where hydrogen becomes cold enough to form [...]

NASA astronaut Jessica Meir works inside the International Space Station’s Quest airlock, installing leg and arm components on a spacesuit and swapping components from one suit to another to prepare for a spacewalk.NASA/Jack Hathaway The Expedition 74 crew members spent Wednesday studying the cardiovascular system while preparing for a spacewalk to upgrade the orbital outpost’s [...]
NASA’s University Innovation (UI) project funds university-led innovation to address the agency’s Aeronautics Research Mission Directorate’s system-level challenges via independent, NASA-alternate-path, multi-disciplinary awards. Strategic Goals The UI portfolio’s strategic goals in descending order of importance are: 1. Assist in achieving aviation outcomes defined in the ARMD Strategic Implementation Plan through NASA-complementary research. 2. Transition [...]
