Contrary to the assumptions of early paleontologists, most dinosaurs weren’t lumbering slowpokes. Centuries of evolutionary reevaluation now indicates the ancestors of present-day birds didn’t simply keep a steady pace—many of them boasted impressive speed. These active lifestyles also forced scientists to reconsider another anatomical detail. Once thought universally cold-blooded, a lot of dinosaurs eventually evolved
A World War I submarine that sank nearly 110 years ago has been leaking explosive pollutants into the North Sea for decades. What’s more, ocean researchers say the problem may worsen over time—not only near the German vessel itself, but at thousands of similar shipwrecks. On April 19, 1917, Germany’s UC-30 submarine was attempting to
Astronomers have confirmed a world that’s less than a million years old as the youngest known planet, using data from NASA-funded archives. Called Elias 2-24 b, the baby planet is still whirling in its natal disk of dust and gas. “Our planet-formation models already struggled to explain the previous record holders for the youngest known
Planning crewed missions to the Moon and Mars involves preparing for the medical realities of long-duration space travel. Factors like cosmic radiation, microgravity, and distance from Earth create unique health considerations for astronauts. To anticipate these needs ahead of time, NASA developed the Integrated Medical Model (IMM). The IMM is a decision-support tool that uses
As part of NASA’s new Inspiration Tour, Reid Wiseman, NASA astronaut and commander of the agency’s Artemis II mission, will highlight America’s strengths in space exploration and aeronautics innovation at the Baltimore Ravens vs. New Orleans Saints game in Baltimore on Sunday, Sept. 20. A Baltimore native, Wiseman is a 27-year Navy veteran and NASA
Long before they helped shape NASA’s future aerospace breakthroughs, Derek Abramson, Justin Hall, and Justin Link were in their garages and homes building radio‑controlled aircraft, testing new ideas, and flying their creations at hobby events. That early passion now fuels the work of NASA’s Dale Reed Subscale Flight Research Laboratory at the agency’s Armstrong Flight
