Aurora borealis
Aurora borealis. Fish-eye lens view of a tree silhouetted against a red aurora borealis or northern lights display in the night sky. Aurorae, named after the Roman goddess of the dawn, are caused by the interaction of charged particles from the suns solar wind with the Earths magnetic field. The aurorae are seen at high latitudes, as these particles are channelled to the poles by the Earths magnetic field. The particles collide with air molecules at heights from 80 to 1000 kilometres above the Earth. The colour of light emitted varies with air pressure and the gases involved, to give rise to flickering cascades of colour. Photographed in Finland

EDITORS COMMENTS
This print captures the mesmerizing beauty of the Aurora borealis, also known as the northern lights. The image showcases a striking silhouette of a tree against a backdrop of vibrant red aurora borealis dancing in the night sky. Aurorae, named after the Roman goddess of dawn, are a result of charged particles from the sun's solar wind interacting with Earth's magnetic field. These breathtaking displays are predominantly seen at high latitudes, where these charged particles are directed towards the poles by Earth's magnetic field. The collision between these particles and air molecules occurs at heights ranging from 80 to 1000 kilometers above our planet's surface. It is this interaction that gives rise to flickering cascades of color, with different gases and air pressures influencing the emitted light's hues. Photographed in Finland, this image perfectly encapsulates nature's awe-inspiring spectacle. The combination of an enchanting silhouette against a vivid display creates an ethereal atmosphere that transports viewers into another world. The use of a fish-eye lens adds depth and perspective to this already stunning composition. By capturing such vast expanses within its frame, it emphasizes both the grandeur and delicacy inherent in this natural phenomenon. As we marvel at this photograph, let us appreciate how Earth science unravels atmospheric phenomena like aurorae through understanding electromagnetic effects caused by solar activity and our planet’s magnetic field. Science Photo Library brings us yet another remarkable glimpse into nature’s wonders with their collection featuring not only scientific imagery but also artistic masterpieces like this one – reminding us once again why our world is so fascinatingly beautiful.
