A new Chinese freighter spacecraft arrived at the Tiangong space station last week, packed with supplies. Tianzhou 9 launched July 14 atop a Long March 7 rocket at 5:34 p.m. EDT (2134 GMT; 5:34 a.m. on July 15 China Standard Time), sending the spacecraft into orbit. Just over three hours later, at 8:52 p.m. EDT (0052 GMT; 8:52 p.m. China …

A fascinating discovery in the world of paleontology has shattered the Hollywood-inspired image of dinosaurs popularized by films like Jurassic Park. A newly identified dinosaur species, Pulaosaurus qinglong, discovered in China, presents a significant shift in how scientists think about dinosaur behavior. Instead of the traditional portrayal of terrifying, roaring creatures, Pulaosaurus is believed to have communicated with chirps, much …

Blue Featherleg (Damselfly) Marit van Ekelenburg turns “fear into fascination” by revealing the beauty, diversity, and ecological importance of insects and other invertebrates through macro photography. To some, the arthropod kingdom of insects and arachnids has been unjustly vilified. In response, Ekelenburg snaps small portraits with big meaning, showing that a demure weevil, a fuzzy jumping spider, or a furry …

When time lost to shortened days begins to add up, timekeepers add an extra second to the running clock, bringing astronomical time back in sync with the atomic time it had lagged behind. This is called a leap second, and it’s been implemented about every year and a half since 1972—most people don’t notice that either. Will a faster-spinning Earth affect …

Summary: New research shows that our brain’s internal map rewrites itself every time we navigate a familiar environment. Even when mice experienced identical virtual mazes with controlled sensory input, their hippocampal neurons activated in different patterns on each run. This suggests spatial memories are dynamic, evolving rather than fixed, and may encode the passage of time. The findings offer insights …

A century-old hypothesis that Betelgeuse, the 10th brightest star in our night sky, is orbited by a very close companion star was proved true by a team of astrophysicists led by a scientist at NASA’s Ames Research Center in California’s Silicon Valley. The research published in The Astrophysical Journal Letters in the paper “Probable Direct Imaging Discovery of the Stellar …

In a recent study published in Communications Earth & Environment, researchers have uncovered an astonishing revelation about the Moon’s surface, challenging previous beliefs about its exosphere. While it was once thought that solar wind and meteoroid impacts were primarily responsible for the creation of the Moon’s thin exosphere, new findings suggest that the Moon’s surface features—such as its roughness and …

A team of scientists has found the recently discovered “interstellar invader” comet 3I/ATLAS is teeming with water ice. This water could have been sealed in the comet for 7 billion years, which would make it older than the solar system itself. The team also found a mixture of organic molecules, silicates and carbon based minerals on the object, meaning 3I/ATLAS …
