Citizen-Driven Radio Telescope Network Decodes Hidden Signals from the Cosmos

Featured image

An international collaboration of amateur and professional astronomers has deployed a distributed network of low-cost radio telescopes to track and analyze fast radio bursts (FRBs). Using software-defined radio dongles, home-built Yagi-Uda antennas, and single-board computers, volunteers have helped pinpoint a repeating FRB source, shedding light on one of astronomy's greatest mysteries.

Stratospheric Microplastics Unveiled: Researchers Map Plastic Pollution High Above Earth

Featured image

A recent international study reveals the surprising presence of microplastic particles high in the stratosphere, prompting questions about long-range transport, climate impacts, and human health. Using high-altitude balloons and laser-based sensors, scientists have mapped airborne plastic fragments up to 20 kilometers above ground, highlighting a new frontier in environmental monitoring.

Autonomous Gliders Uncover Microplastic Eddies in Coastal Waters
