Oct 24, 2026 5:00 AMThe Webb telescope sees tiny red dots everywhere. Astronomers can’t agree on what they are, but some believe they may be enormous stars with black holes inside.

Astronomers built the James Webb Space Telescope to pick up faint light from the first billion years after the Big Bang, a chaotic era when vast swaths of hydrogen and helium gas gathered into the chains of galaxies we see today. Even in the telescope’s first images, astronomers could see a whole zoo of mysterious smears of light. One batch of objects proved especially difficult to interpret. They glowed blindingly bright, emitting red light with long wavelengths and shining as brilliantly as a whole galaxy. They were tiny, spanning just a pixel. And they were everywhere. A couple appear in almost every image Webb takes. In 2023, researchers started calling them “little red dots.” Astronomers have repeatedly pointed Webb toward the little red dots, wringing precious new information from these pixels of light. Initially, researchers thought the dots looked kind of like galaxies.

But for centuries, a strange picture of a more eerie form has emerged. Thousands of records and eyewitness accounts have told of balls of lightning hovering above the ground before disappearing in a pop like soap bubbles. This fleeting phenomenon is all but impossible to study – and reports vary wildly in descriptions of its size, its hue, and even its behavior, making it one of the most peculiar mysteries in atmospheric science. But if you can't catch ball lightning in a field, physicist Chuliang Zhou and colleagues at the Chinese Academy of Sciences have reasoned, maybe we can learn more by reproducing something like it in a lab. "Here we report the first controlled generation of a macroscopic, long-lived soliton driven by relativistic terahertz electromagnetic fields," the researchers write in a paper published in Nature Photonics.

Mercury ends its prograde motion and prepares to enter retrograde in Libra the Balance — spot it after sunset if you’re quick. Mercury hangs just 1° above the western horizon half an hour after sunset on October 24. Look for the stars of Scorpius in the southwest to help guide you toward the planet’s position.

The first thing people think of when talking about a paleontological discovery is that it takes place in the field. Dinosaur fossils gradually emerge after the meticulous use of special instruments. But a group of scientists has just made an important discovery without digging it up, instead searching through stored drawers.
