Known as the "Cat's Tail," a vast cloud of dust wafting across a young star system could be the aftermath of a collision between two or more Pluto-sized bodies annihilated to microscopically small dust grains. The first observations of the feature in visible light also revealed that the dust grains are extremely porous, a finding that has researchers stumped. 

Comets didn’t seed life on Earth after all, a new study suggests, potentially overturning a century-old idea.

The Earth is surrounded by an invisible barrier that was thought to prevent highly energetic electrons from reaching closer to our planet. But in 2024, Japan’s Arase space probe detected these electrons well inside the barrier. Now, research led by Nagoya University has found evidence that the electrons were accelerated locally rather than infiltrating from outer radiation belts.

A new mapping framework uses satellite data and machine learning to distinguish monoculture from intercropped maize across Kenya’s rainy seasons.
