Antarctica map. A planet full of mystery

Antarctica map. A planet full of mystery

It is not easy to make a map of Antarctica. The southernmost continent on Earth is so cold and inhospitable that a large part remains unexplored.

However, from space, it is possible to map this entire region by radar, based on systematically pointing out how long it takes for radio waves to bounce on the ground.

The Canadian RADARSAT satellite has been orbiting the Earth for years by mapping with its radar, and has edited the most detailed map of Antarctica ever created. The photograph shows a computer-generated map of Antarctica of relatively low resolution.

From the RADARSAT map, scientists have been able to better study this mysterious continent, including information on how ancient ice shelves crumble.
