Imaggeo On Monday: over 10 years of the EGU Photo Competition

Patterns in the Void by Christian Klepp

In 2010 EGU held our first annual Photo Competition at the General Assembly in Vienna. Since then hundreds of photos have been shared on imaggeo by geoscientists and researchers just like you, with a lucky few being selected each year to be highlighted during the meeting and voted on by our members.


These images can be of anything to do with geology or geoscience – we get many beautiful landscape images, but you can also upload laboratory images, fieldwork images, hand samples or microscope images; even videos! The winners are awarded a free registration to the EGU General Assembly the following year and you can share an image taken at any time – they don’t have to be just from the last year – we even accept historical images, as long as you have the rights to share them! For more information visit the 2021 Photo Competition announcement page.


This week’s Imaggeo on Mondays highlights the 2010 Photo Competition winner: an amazing view of the night sky at new moon.

Christian Klepp took this photo while at Waterton Glacier in the Rocky Mountains – it’s an incredible feat of determination to spend the night beside a glacial lake in the Rockies, let alone to capture such a photo!

The centre of the Milky Way lies just over the horizon, shrouded by clouds of interstellar dust. To the left of it is Jupiter – the brightest spot in the photo.

Jupiter orbits the sun at a distance of about 778 million kilometres (Earth is about 150 million kilometres away), taking twelve times longer than Earth to make the trip. Unlike our atmosphere, Jupiter’s is rich in hydrogen and helium – the elements that fuel our sun – and if this gas giant had been 80 times bigger, it would have been a star too – and would have been considerably brighter than it is in Klepp’s photo!

Imaggeo is the EGU’s online open access geosciences image repository. All geoscientists (and others) can submit their photographs and videos to this repository and, since it is open access, these images can be used for free by scientists for their presentations or publications, by educators and the general public, and some images can even be used freely for commercial purposes. Photographers also retain full rights of use, as Imaggeo images are licensed and distributed by the EGU under a Creative Commons licence. Submit your photos at
