Satellite eye onto earth

Ireland, the UK, northern France, the Benelux countries and Rhine valley make a web of lights as seen from space at night 
A massive ice island breaks free of the Petermann Glacier in north-west Greenland. The giant iceberg, 12.5 sq miles (32 sq km) could be seen drifting down the fjord, away from the floating ice tongue from which it had calved
  This image captured by the Pleiades satellite shows the island of Mont Saint Michel and its surrounding bay in north-west France. Mont Saint Michel was a tidal island, surrounded by water at high tide, accessible by foot only when the water recedes. In the late 1800s, the causeway was raised to make it accessible from the mainland at all times. The image shows where the water meets the mud flats, with multiple channels weaving through the mud




Wildfires, Valencia, Spain: as water-bombing aircraft flew overhead, about 3,000 residents were forced to evacuate their homes. The fires followed one of the driest winters in decades, and raged amid temperatures in excess of 40C, low humidity, and high winds. Fires blew thick smoke towards the north-east, and smoke from the fire south-west of Valencia passed directly over the city

Land of lakes, Canada: during the last Ice Age, nearly all of Canada was covered by massive ice sheets. Thousands of years later, the landscape of Nunavut Territory — 'our land' in the Inuktitut language — still shows the scars of that icy earth mover. Surfaces that were scoured by retreating ice and then flooded by Arctic seas are now dotted with millions of lakes, ponds, and streams. The image above shows wetlands in the Kitikmeot region of Nunavut Territory. Water is various shades of blue, green, tan, and black, depending on the amount of suspended sediment (silt and clay) and phytoplankton. Vegetated land is red
