Scientists are uncovering new clues that a cosmic explosion may have rocked Earth at the end of the last ice age. At major Clovis-era sites, researchers found shocked quartz—evidence of intense heat ...

People have long asked whether the world they experience is fundamentally real or the product of a simulation, a question often framed today as the simulation hypothesis. A new paper examines a ...

Deep beneath the Earth lies a mysterious and powerful force. A wellspring of nuclear energy which could one day rip us apart. Many scientists have found clues that natural nuclear reactions have ...

Gold, uranium, and other heavy elements on Earth did not form here. They were born in the violent deaths of massive stars and the collisions of neutron stars, traveling across the galaxy before ...

A simulation has shown the devastating impact 3I/ATLAS could have if it crashed into Earth. The interstellar space object was first identified by the NASA-funded ATLAS telescope in Chile over the ...

For months now, astronomers have been closely watching the mysterious interstellar object 3I/ATLAS as it rips through the solar system at a breakneck velocity. And before it finally leaves us for good ...

NASA's Hubble Space Telescope caught a glimpse of 3I/ATLAS – in July and on Nov. 30, 2025. An ESA orbiter bound for Jupiter also observed the interstellar comet 3I/ATLAS. How big is 3I/ATLAS ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

The moon's surface may be more than just a dusty, barren landscape. Over billions of years, tiny particles from Earth's atmosphere have landed in the lunar soil, creating a possible source of ...

The interstellar comet 3I/ATLAS will make its closest approach to Earth on Dec. 19. Originating from outside our solar system, the comet is not a threat to Earth. While not visible to the naked eye, ...

Scientists believe they’ve found evidence that life on Earth is over a billion years older than anyone believed was realistic. New research used machine learning to scan ancient meteorites and fossils ...
