Portrait of our planet

Photo challenge

Schlieren candles by adavidhazy

By James Dacey

Thank you to everyone who took part in the first ever Physics World photo challenge. We asked readers to submit photos to our Flickr group relating to the theme of “light in physics”. We had some great submissions, a selection of which are showcased in this article.

The theme for our new photo challenge is “portrait of our planet”. To tie in with this month’s earth-sciences special issue of Physics World, we want you to submit photos to our Flickr group relating to the scientific study of the physical Earth. It might relate to a geophysical phenomenon such as a fiery volcanic eruption, a tornado or the aftermath of an earthquake. Or you might choose to share a more abstract vision of our planet, such as a colourful geological rock formation or a spectacular ice feature. Be as creative as you like.

Please add your photos by Tuesday 27 March and then after this date we will choose a selection of our favourite images to be showcased on

Please also feel free to write a caption to share the story behind the image. Your photos may show an interesting geophysical phenomenon, or may have required some inventive and time-consuming photography. Perhaps, in capturing the perfect shot, you camped out overnight in an isolated wilderness, or maybe you scaled the slopes of a mountain in search of a striking landscape.

Expensive equipment is not necessarily required, however. People prove every day that you can capture an inspiring snapshot using the most basic of cameras, even the one on your mobile phone.
