Satellite spots spider-like formations on Mars

The European Space Agency (ESA) has announced that the 'spiders' spotted by the agency’s Mars orbiter are actually geological features. When sunlight mixes with carbon dioxide, it triggers the release of gases that fracture ice, allowing dust to reach the surface and form spider-like figures. According to scientists, these figures are not small and measure anywhere from around 50 yards to over half a mile wide.
