India, Jan. 16 -- Researchers unveiled a detailed map of Antarctica's landscape beneath ice sheets.

It reveals diverse terrains such as alpine valleys and deeply eroded troughs.

Map was created using satellite data and the Ice Flow Perturbation Analysis method.

People on Earth know more about the surface of Mercury than the landscape underneath the ice sheets of Antarctica. But that is set to change. A group of researchers has developed a novel method to visualise the relief many kilometres below the ice cover.

By using satellite data to identify ice surface and utilising the physics behind how ice moves over a "bedrock" feature or the landscape under an ice sheet, researchers were able to map the landscape of Antarctica.
