A simulation of every asteroid hitting Earth at once
Sixty-six million years ago, this asteroid crashed into Earth and wiped out most of the life on our planet. Including the biggest, baddest things that ever roamed the planet. Yeah, dinosaurs. If 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 ...
Scientists confirmed the object originated outside our solar system due to its high speed and trajectory. The comet poses no danger and will pass about 170 million miles from Earth. While not visible ...
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 is monitoring a bus-sized asteroid that’s soaring towards Earth at nearly 8,000 miles per hour, according to the space agency's Center for Near Earth Object Studies (CNEOS). Estimated to measure ...
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 ...
Two enormous structures that sit at the border between the Earth’s mantle and its core have puzzled scientists for decades, defying reigning theories of how our planet came to be. In a new study ...
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, ...
