A seemingly simple set of rules kicks off a kind of mathematical magic trick, which has kept great minds busy since the 1930s. Columnist Jacob Aron explores the origins of the Collatz conjecture, why it is so addictive to mathematicians and whether AI could help us solve it once and for all

What is so micro about tonight's blue micromoon?

A gorgeous spiral galaxy,

A geomagnetic storm expected June 4th arrived late. But there's still at chance of seeing auroras Friday night, June 5th.

Astronomers have developed a technique that allows them to detect cloud cycles on distant exoplanets. Using data from the James Webb Sapce Telescope (JWST), the astronomers found that mornings and evenings on the gas giant WASP-94A b have extremely different weather patterns: mornings are riddled with sand clouds, while the skies are clear in the early evenings. By isolating the clouds, researchers can more accurately measure a planet’s atmosphere and provide a clearer picture of the planet’s composition. WASP-94A b, for example, has much less oxygen and carbon than astronomers perviously calculated, making its atmosphere much more like Jupiter than they had originally thought.
