epa05318437 A handout photograph made avaiable on 20 May 2016 showing the plant Mars covered in clouds viewed by the Hubble Space Telescope on 12 May 2016. The image taken to show off the effects the seasons have on the red planet. This observation was made just a few days before Mars opposition on 22 May 2016, when the sun and Mars will be on exact opposite sides of Earth, and when Mars will be at a distance of 47.4 million miles from Earth. On 30 May 2016 Mars will be the closest it has been to Earth in 11 years, at a distance of 46.8 million miles. Mars is especially photogenic during opposition because it can be seen fully illuminated by the sun as viewed from Earth. EPA/NASA / HUBBLE / HANDOUT HANDOUT EDITORIAL USE ONLY/NO SALES
