    This breathtaking photo of Ireland was captured by former NASA astronaut Terry Virts on 13 March 2015 from the International Space Station. The clouds seem to have parted to enable Virts to get the shot, just 4 days ahead of St Patrick's Day. Easily discernible in the northeast of the island is Lough Neagh, located in Northern Ireland and the largest freshwater lake on the whole island. Also visible in the image are the curvature of the Earth and solar panels providing solar energy to the ISS. Credit: NASA/ESA/Terry Virts
