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 …[Read More]
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 …[Read More]

It’s that time of year again! Yes, today, the 13 January, the thirteenth annual EGU photo competition opened for submissions!! Until 31 March, every participant …[Read More]
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 …[Read More]
In Sweden a beautiful Northern Lights show proceeds unnoticed by the busy drivers passing by. The Northern Lights or Aurora Borealis are spectacular lights created as a result of disturbances in the Earth’s magnetosphere caused by solar winds. They are visible at both polar regions and or often seen as veils or lines of greenish-blue …[Read More]
Melt water lakes are an impressive and beautiful consequence of warm summer temperatures on Greenlands glaciers. This photo of such a lake with clear blue water was taken from a helicopter on the 79°N Glacier in northeast Greenland during an expedition in July 2018. Supraglacial melt water runs along the surface slope into depressions where …[Read More]
During parts of the dark Arctic winter, the sun only as much as touches the horizons, melting sunrise into sunset in a dramatic flash of red light. Photo by Maria Scheel, description from imaggeo.egu.eu. Imaggeo is the EGU’s online open access geosciences image repository. All geoscientists (and others) can submit their photographs and videos to this repository …[Read More]
First, in English: Bottom of a dry lagoon in the Cañada de Los Pájaros (Birds Dale) in the surroundings of the Doñana National Park (Huelva, SW Spain). After an exceptionally long, hot, and dry summer, the area’s lagoon system has dried up. The bottom, clayey and silty, contracts to form a network of columnar aggregates …[Read More]
S-C mylonites developed in andalusite-cordierite micaschist (Calamita Schists) in the contact aureole of the Porto Azzurro pluton. The white layers are made of quartz, while the brown layers consist predominantly of white mica and biotite. Top-to-left (East) sense of shear. Read more: Papeschi et al (2017). Heterogeneous brittle-ductile deformation at shallow crustal levels under high …[Read More]
A tribute to the computational geosciences. A mix of computer infrastructure, a modern workstation, and a simple globe with coastlines. Found this scene at the back of room at Miraikan – the National Museum of Emerging Science and Innovation in Tokyo, Japan. The computers, screens, and globe are behind a plexi-glass and while not intended …[Read More]
