UK-led study reveals hidden massive star clusters deep within nearby galaxies
Astronomers using the VLA and ALMA uncovered previously unseen giant star clusters embedded deep inside nearby galaxies. The findings show that young stellar activity drives the evolution of these galaxies, reshaping their interstellar environments. Multiple observations confirm the clusters act as hidden “ring factories” of star formation.

A 19m-Long Giant Octopus Roamed the Cretaceous Seas
Scientists publishing in Science report that fossilized beaks indicate a Cretaceous octopus reaching roughly 19 meters—about the length of an 18‑wheel truck—making it potentially the largest invertebrate ever recorded. These eight‑armed, finned cephalopods lived 66‑145 million years ago, predating the last dinosaurs, and their size rivals or exceeds that of today’s giant squid. The beak evidence shows they could crush hard‑shelled prey and may have been capable of attacking large vessels. The discovery forces a rethink of predator hierarchies in ancient seas.
