The Space Weather Prediction Center, part of the National Oceanic and Atmospheric Administration, reported that the solar particles, which were ejected on Tuesday evening, arrived at 11:15 a.m. Eastern time, traveling at nearly 1.5 million miles per …

J. Robert Oppenheimer teemed with contradictions. He was shy and bold, naïve and brilliant, a loyal husband who cheated, a gentle man whose bomb could kill millions. That he loved quantum physics may be no accident. The field holds that some basic phenomena of the material world have opposing features …

John J. Hopfield and Geoffrey E. Hinton received the Nobel Prize in Physics on Tuesday for discoveries that helped computers learn more in the way the human brain does, providing the building blocks for developments in artificial intelligence. The award is an acknowledgment of A.I.’s growing significance in the way …

Look up, stargazers: A comet discovered last year is getting brighter as it makes its closest pass by Earth later this week, and this could be humanity’s last chance to see the comet before it disappears into the cosmic depths. The celestial visitor is Comet Tsuchinshan-ATLAS, or C/2023 A3 to …

It may seem like a hopeless place, but locusts find a way to breed in the scorching heat of the Sahara at midday. The biblical voracity of these insects make them among the world’s most destructive pests. They devour agricultural crops in swarms that number in the billions and stretch …

It’s also staggeringly tall — and, with a peak 29,032 feet above sea level, it easily achieves the status of …
