World's Youngest Island - Hunga Tonga Hunga Ha'apai



Welcome to Hunga Tonga Hunga Ha'apai (HTHH). It's the world's youngest island and it was emerged from an underwater pacific volcano in 2015 between two Tongan islands which it was named after. Scientists expected HTHH to erode within months, but it's hanging on.


They now think it could take up to 30 years to deteriorate. That's great news because they think there are similar formations on Mars. So maybe this baby island could unlock some clues to life on the Red Planet?
