Tiny NASA Spacecraft Delivers Exoplanet Mission’s First Images
With the first images from the spacecraft now in hand, the team behind NASA’s Star-Planet Activity Research CubeSat, or SPARCS, is ready to begin charting the energetic lives of the galaxy’s most common stars to help answer one of humanity’s most profound questions: Which distant worlds beyond our solar system might be habitable? Initial, or “first light,” images mark the…

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 the Euclid space telescope, an ESA (European Space Agency) mission with critical contributions from NASA, we can now see…

Efficient Large Displacement/Large Rotation Dynamic Simulations Using Nonlinear Dynamic Substructures
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 Henkel-Mar pad separation analysis methodology…

Dust Outbreak Reaches Europe
Winter winds lofted clouds of dust from the Sahara Desert, carrying it north toward the Mediterranean and dispersing it widely across Europe in March 2026. When the dust combined with moisture-laden weather systems, a dirty rain fell in parts of Spain, France, and the United Kingdom. This animation highlights the concentration and movement of dust throughout the region from March…

A Most Unusual Lake
Scientists estimate that Earth is home to more than 100 million lakes. Among the most unusual is Lake Unter-See, one of Antarctica’s largest and deepest surface lakes, known for its distinctive water chemistry. Its ice-covered waters have exceptionally high levels of dissolved oxygen, low dissolved carbon dioxide, and a strongly alkaline (basic) pH. The OLI (Operational Land Imager) on Landsat 9 captured this image on February…
