A fossilized Edmontosaurus skull with a Tyrannosaurus tooth still embedded in its face has given scientists rare evidence of a dramatic predator-prey encounter。 The discovery suggests the giant carnivore delivered an incredibly powerful face-to-face bite, offering new clues about how Tyrannosaurus hunted
The FCC authorized Reflect Orbital to launch the mirror satellite Eärendil-1。 “For optical astronomy, this poses an existential threat,” the European Southern Observatory said
Dark matter may be far more complicated than scientists once believed。 A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outward。 This simple idea could explain several puzzling cosmic observations
Scientists have developed a new framework that could finally apply the laws of thermodynamics to real, ever-changing black holes instead of only perfectly stable ones。 The advance may improve our understanding of black hole mergers, evaporation, and the powerful gravitational wave events detected by observatories like LIGO
K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes。 Advanced software analyzed millions of signals, filtering out Earth-based interference and other false positives。 No convincing artificial radio transmissions wer
