Sentinel-2B imaged the highest mountains of western Europe, just the moment an airplane was about to fly over the granite peaks of Grandes Jorasses and cross the border from France to Italy. The passengers on the right side of the plane must have enjoyed a spectacular view on Mont Blanc, just nine kilometers away to the south-west, and Mer de Glace, the longest glacier in France flowing down from ...[Read More]

Northern lights in Tromsø, displaying the collisions between electrically charged particles from the sun which penetrate the earth’s magnetic shield and strike atoms and molecules in our atmosphere. Collisions excite the atoms causing electrons to move to higher-energy orbits, further away from the nucleus. When electrons move back to lower-energy orbits, they release particles of light call ...[Read More]

Colucci, it’s also one of the best time’s to study the Earth’s underground cryosphere. Colucci, who took this featured photograph, is a researcher at Italian Institute for Marine Sciences (ISMAR) of the National Research Council (CNR) and i ...[Read More]

This magnificent pattern is the result of hundreds and hundreds of years of evolution. In this structured minerotrophic peatland in Northern Quebec (Canada), which can also be called a string fen or aapa mire, the green peat ridges (or strings) alternate with water-filled hollows (or flarks). Often flarks are replaced by ponds, which vary in number and size. This pattern of strings and flarks (or ...[Read More]
