The head of the Trump administration's Golden Dome program says the technologies needed to create such an ambitious space-based missile defense system already exist.

Astronomers have found a baby system that’s just beginning to build planets — and it can tell us about how and where planet formation starts.

Researchers hoped CMB-S4, a $900-million cosmology experiment, would answer one of the greatest questions in physics. Instead it’s become another cautionary tale of pursuing big science amid shrinking budgets

Scientists have examined the interstellar invader 3I/ATLAS, finding evidence that it is packed with water that could be older than the solar system.

High humidity and low overnight temperatures will put tens of millions of people under heat alerts over the course of the coming week

Claims that a small-brained hominin called Homo naledi buried its dead raise intriguing questions about ancient minds and why we engage in this peculiar practice

A 247-million-year-old fossil reptile boasted an enormous crest on its back made from feather-like appendages, long before the appearance of feathered dinosaurs

With fast heating, sheets of gold can shoot past the theoretical maximum temperature a solid can have before it melts – raising questions about what the true limits are

With fast heating, sheets of gold can shoot past the theoretical maximum temperature a solid can have before it melts – raising questions about what the true limits are

Physicists superheated gold to 14 times its melting point, disproving a long-standing prediction about the temperature limits of solids

As large language models like Claude 4 express uncertainty about whether they are conscious, researchers race to decode their inner workings, raising profound questions about machine awareness, ethics and the risks of uncontrolled AI evolution
