Summary:

- Satellites have used X-ray technology to create a detailed map of the bedrock beneath Antarctica's ice sheet, revealing previously hidden features like mountains, canyons, and over 72,000 hills.
- This new map provides a better understanding of the landscape hidden under the thick ice, which is important for studying the region's geology, climate, and potential for future exploration.
- The data collected can help scientists predict how the ice sheet may respond to climate change and how it has changed over time, as the hidden features influence the flow and melting of the ice.
