Imja Glacier, Himalayas, Nepal


This satellite image shows an area of the Himalaya mountain range in northeastern Nepal, about 8 km south of Mount Everest (not pictured).

The Himalayas are the world’s highest mountain range and home to the world’s highest peak, Mt Everest (about 8850 m), as well as dozens of other peaks over 7000 m high. These high peaks are covered permanently with snow.

The range is also home to thousands of glaciers, including the Imja glacier in the upper-central part of this image. Studies have shown an increase in the rate of glacial retreat for Imja and many other glaciers in the region – and in the world.

Glaciers are the largest reservoirs of freshwater on our planet, and their melting or growing is one of the best indicators of climate change. Satellite radar data can help monitor changes in glacier mass and, subsequently, their contribution to rising sea levels.

Glacial runoff from the Himalayas has a direct effect on the nearby rivers such as the Indus and Ganges, and is very important for lower-lying regions where there is a very large human population.

At the foot of the Imja glacier is the Imja lake, pictured in the upper-left. Melt-water makes this one of the fastest growing lakes in the Himalayas, and a threat to downstream communities.

This image, also featured in the Earth from Space video program, was acquired by the Kompsat-2 satellite on 14 January 2013.

The Ganges Delta


Proba-V images the Ganges Delta, the world’s largest delta, in the area of Bangladesh and India. The delta plain, about 350 km wide along the Bay of
Bengal, is formed by the confluence of the rivers Ganges, the Brahmaputra and Meghna. This Proba-V Vegetation image was acquired on 2 February 2014 at 100 m spatial resolution.
