High-resolution images from ESO’s Very Large Telescope and the Large Binocular Telescope reveal that the E-type asteroid (44) Nysa may be unlike any other world in the Solar System, with three connected lobes and a newly discovered satellite that could help explain how the bizarre object formed. This image of the Nysa system was captured on February 15, 2026. Image credit: Minker et al., arXiv:...

NASA’s Curiosity rover has stumbled on the largest patch of polygon-shaped ground fractures it has ever seen on Mars, a discovery that could reveal more about the planet’s watery past.

The unusual terrain lies in a valley known as Valle Grande on the lower slopes of Mount Sharp inside...

Archaeologists in southwestern Germany have unearthed two miniature bird figurines carved from mammoth ivory, among the smallest and most delicate examples of Ice Age art ever found.

Paleontologists working in southern Wyoming have identified a previously unknown species of omomyid primate, adding a new chapter to the story of one of the best-studied fossil lineages in North America. Tetonius homunculus (colorized) by R. Bruce Horsfall from W.B. Scott’s History of Land Mammals in the Western Hemisphere. The new species belongs to a family of small, big-eyed, tarsier-like primates...

Moving a free-roaming cat indoors for good is a decision many owners approach with dread: guilt over confining a former outdoor explorer, worry about litter boxes and scratched furniture, and doubts about whether the cat will ever adjust. But according to a new survey of cat owners in New Zealand, the transition tends to go more smoothly than expected, even when it isn’t planned at all. The owner...

Using the largest sample yet of particles called beauty mesons, physicists with the CMS Collaboration at CERN’s Large Hadron Collider (LHC) refined a decades-old test of the subtle imbalance that let our Universe exist at all. Neutral beauty mesons can turn into their own antimatter opposite and back again. Image credit: Ansar Iqbal / CMS. One of the greatest mysteries in physics is why the Universe...

In a perspective paper published in The American Journal of Clinical Nutrition, a team of researchers and health experts calls for a ‘paradigm shift’ in how public health agencies address hypertension, which affects more than 1.28 billion adults worldwide and remains a leading driver of cardiovascular disease. The authors say high blood pressure can be controlled better with a strategy that combines...

New research led by the University of California, Berkeley reveals that beyond Neanderthals and Denisovans, humans interbred with two mysterious ‘ghost’ lineages: one in Africa more than 50,000 years ago, another in Eurasia over 1.7 million years ago.

Zircon crystals and impact-altered minerals show that a massive asteroid slammed into what is now the Pilbara region of Western Australia about 3 billion years ago. The North Pole Dome crater: (A) simplified map of the East Pilbara Terrane (EPT, Western Australia), showing Paleoarchean granite domes (pink) and greenstone belts (greens and blues); the North Pole Dome (NPD) lies near the terrane center;...
