Scientists are now spotting whales from outer space using satellites

A humpback whale may be a huge creature to the human eye, but they're still tough to spot from space.

Until recently, the necessary high-resolution satellite technology wasn't readily available, but researchers in Western Australia are beginning to use satellite imagery to check on the size of local populations.

The aim of the project is to keep tabs on Western Australia's humpback whale numbers, explained Curt Jenner, managing director of the Centre for Whale Research.

"The goal of the project is ultimately to make sure this population of humpback whales, which has always historically been the largest in the world, is still viable and has recovered to its full potential," he said.
