Hold on to your hats, or in this case, your helmets: Scientists have finally pinpointed the so-called edge of space — the boundary between Earth's atmosphere and outer space. picked by AutumnLotus 8 months ago

Scientists analysing data gathered by the Cassini spacecraft have confirmed the presence of heavy negative ions in the upper regions of Titan’s atmosphere. These particles may act as organic building blocks for even more complicated molecules and their discovery was completely unexpected because of the chemical composition of the atmosphere (which lacks oxygen and mainly consists of nitrogen... read full post picked by AutumnLotus 2 years ago

A space storm has been observed exploding from a central point in Earth's upper atmosphere for the first time. The result could one day lead to better predictions of the storms, which can harm satellites and power grids on the ground. picked by AutumnLotus 6 months ago

Scientists have solved a 40-year-old puzzle by identifying the origin of the intense radio waves in the Earth's upper atmosphere that control the dynamics of the Van Allen radiation belts — belts consisting of high-energy electrons that can damage satellites and spacecraft and pose a risk to astronauts performing activities outside their spacecraft. picked by AutumnLotus 2 years ago

Earth's tropical belt seems to have expanded a couple hundred miles over the past quarter century, which could mean more arid weather for some already dry subtropical regions, new climate research shows. picked by AutumnLotus 2 years ago

Los Angeles can continue being the butt of smog jokes now that it has once again topped the American Lung Association's bad air list of most polluted cities in America. picked by AutumnLotus 3 years ago
