Antarctica in Hi-Def


The Landsat Image Map of Antarctica released today is the most detailed view yet of the Southern continent. The map is made up of 1100 images from the Landsat 7 satellite. Many mysteries remain about Earth's last frontier. Worlds like Enceladus have "hot spots" in their South poles due to some mysterious process. Discovery of subglacial lakes in Antarctica hints at some inner source of heat. We associate it with cold, but Earth's South Pole could paradoxically hide another hot spot. The lakes could be homes for life where no light has penetrated. Similiar lakes could exist on moons like Europa. Already Martian meteorites found in Antarctica hint at extraterrestrial life.

Antarctica is also a prime site for telescopes. The ICE CUBE experiment is designed to detect neutrinos from Space and could potentially provide data from Earth's mysterious interior. Dome C near the South Pole is potentially an even better site for telescopes than Mauna Kea. In the 21st century this continent could become a centre of astronomy.

Below is the bridge of Australia's research ship, MV AURORA AUSTRALIS.

Gee, you certainly do get around. And here I thought you were at Princeton this week. Well, have fun wherever you are.

That research ship at Antarctica looks like brilliant fun! But I hope doesn’t sink like the British ship called Explorer that hit an iceberg in Antarctica last week (the hole was only fist-sized, but they may have been lazy and left too many of the water-tight compartment doors open for convenience when people are moving about below deck. It can be a dangerous convenience in those icy seas.

Please keep warm and also make sure you know where to grab your life-jacket and survival raft, just in case the worst happens!
