The European Space Agency takes us over the Galápagos Islands – a volcanic archipelago situated some 1000 km west of Ecuador in the Pacific Ocean.

Lake Titicaca, which borders both Bolivia and Peru, is one of the largest freshwater lakes in South America.
The video is brought to us by the European Space Agency (ESA).
Covering an area of around 8300 sq km, Lake Titicaca lies on the high Andes plateau and straddles the border between Peru (to the west) and Bolivia (to the east). It is considered the highest major body of navigable water in the world, as it sits at an elevation of 3800 m above sea level.

This video from space of San Francisco Bay, California is brought to us by the European Space Agency (ESA).
San Francisco Bay, almost 100 km in length, is a shallow estuary surrounded by the San Francisco Bay Area – an extensive metropolitan region that is dominated by large cities such as San Francisco, Oakland and San Jose. The densely populated urban areas around the bay contrast strongly with the surrounding green forest and park areas.
In the upper right of the image, the delta of the Sacramento and San Joaquin rivers is visible – with the brown, sediment-filled water flowing down into San Pablo Bay. Here, the murky waters mix before flowing into the larger bay area, which is connected to the Pacific Ocean via the Golden Gate strait. A large sediment plume can be seen travelling westward into the Pacific in the left of the image.
The Golden Gate Bridge, around 2.7 km long, is visible crossing the opening of the bay into the Pacific Ocean between Marin County and the city of San Francisco – which can be seen at the tip of the southern peninsula in the centre of the image. Treasure, Angel and Alcatraz islands can be seen sticking out of the waters of the bay, with several bridges connecting its east and west shores. Several boats are also visible.
The bright green and yellow colours in the bottom right of the image are salt ponds and are part of the Don Edwards National Wildlife Refuge. Covering an area of around 120 sq km, the refuge contains salt marsh, mudflat and vernal pool habitats for millions of migratory birds and endangered species.
