magnetic termite mound by christoph-schaarschmidt (http://ift.tt/1N1g0KQ)
Photographing stars you usually need a compass - but not in the Litchfield National Park in the Northern Territory/Australia. Some termites here somehow managed to use the magnetic field of our earth to build this unique kind of mounds, which are alligned from north to south. They look like flat tombstones, but their secret is that the sun warms up the eastern side first after cold nights, while the midday sun only reaches a small part of it directly - so it never gets too hot inside. via 500px http://ift.tt/1PTRBK5
