WASHINGTON, Oct 24 (Reuters) – Antarctica has not always been a desolate land of ice and snow. Earth’s southernmost continent once was home to rivers and forests teeming with life.
Using satellite observations and ice-penetrating radar, scientists are now getting a glimpse of Antarctica’s lost world. Researchers said on Tuesday they have detected buried under the continent’s ice sheet a vast ancient landscape, replete with valleys and ridges, apparently shaped by rivers before being engulfed by glaciation long ago.
