A new paper posits that advanced alien civilizations may communicate through subtle flashes, like fireflies do on Earth. The thought experiment suggests that we need to avoid human biases in our searc...
Scientists drilled to the bottom of Greenland's 1,600-foot deep Prudhoe Dome and found it disappeared in the early Holocene, when temperatures were close to what we're predicted to reach by the end of...
Researchers have proposed a theoretical timepiece, dubbed the "CRASH Clock," which tells us how quickly satellites would start colliding if they lost the ability to avoid each other, such as during a ...
Sophie Germain was a brilliant, self-taught mathematician who won one of France's most prestigious prizes, yet she declined to attend the award ceremony because the committee members didn't respect he...
The massive sunspot that sparked an "extreme" geomagnetic storm in May 2024 unleashed hundreds of other dangerous solar flares, including a hidden X-class outburst, a new paper reveals. The study sets...
China's EAST nuclear fusion reactor has successfully kept plasma stable at extreme densities, passing a major fusion milestone and potentially bringing humanity closer to wielding near-limitless clean...
Recently discovered Comet C/2025 R3 (PanSTARRS) will make its closest approach to the sun and Earth in late April and could potentially be visible to the naked eye. It may end up being the brightest c...
A small town in California was hit by earthquakes once every 22 years for over a century, setting the stage for a major seismic experiment in the 1980s and 90s. But the quake ended up being 11 years l...
New satellite photos reveal that one of the world's largest and longest-lived icebergs, A23a, has developed vibrant blue striations on its surface. The striking snaps hint that the "megaberg" will soo...
