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 ...

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 Gordon Bell Climate Prize-winning team reached a landmark this year by being the first team ever to develop a Full Earth Simulation at 1 km (extremely high) Resolution. St. Louis, MO, November 20, ...

New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon, came from closer to the sun. Artist’s impression of the collision between ...

Astronomers recently detected a stray quasi-moon in our planet’s orbit, but it's hardly the first stowaway to hang out around Earth. Unlike the Earth's moon, quasi-moons are not gravitationally bound ...

Fifty-five years ago, a dead sperm whale washed ashore near Florence — and what happened next became one of the most infamous moments in state history. Engineers from the Oregon Highway Division, ...

Newly discovered comet C/2025 V1 (Borisov), which has some minor similarities to 3I/ATLAS, will make its closest approach to Earth on Tuesday (Nov. 11). However, despite recent rumors, the two objects ...
