Imaggeo On Monday: Blue cements in Jurassic rocks?

Staining of thin sections and rock slabs is a method of identification that has long helped researchers to distinguish certain minerals which often otherwise appeared very similar. Modern studies have now largely replaced this method of identification with more analytical techniques that usually provide a higher degree of certainty, such as analysis with a microprobe or Scanning Electron Microscop ...[Read More]

Imaggeo On Monday: One with the Cosmos

Imaggeo On Monday: One with the Cosmos

Camping under the stars is an experience that allows people to connect with the cosmos in a unique and profound way. As they set up their tents and gaze up at the night sky, they are reminded of the vastness and beauty of the universe. They can see the stars, the planets and other celestial objects, and feel a sense of awe and wonder. They are reminded that they are just a small part of something ...[Read More]

Imaggeo On Monday: Pantone of Blue Mountains, light scattering.

The light’s interaction with matter enables scientists to observe greenhouse gases from space, but also creates the shifting blue tones throughout the mountains that hikers travel long distances to admire! The blue shades are created by an effect called Raleigh scattering, where very small atmospheric particles between the viewer (or camera) and the mountains cause the shorter wavelength lig ...[Read More]

Imaggeo On Monday: Blood moon over Germany

A blood moon occurs during a total lunar eclipse. The sunlight falling through the air layers of the Earth’s atmosphere is refracted inwards, whereby especially the short-wave blue components are weakened by scattering. The long-wave red components, on the other hand, still reach the moon, which leads to the red colouring.   Photo by Simon Fuhrmann shared on imaggeo.egu.eu.   Imagg ...[Read More]
