... The telescope buildings sit on stilts, so that snow drifts won't bury them. Here, a 5-minute snowmobile ride from the South Pole, is the most remote observatory on Earth. Astronomers have a reputation for going to far-off places to watch the stars, but even their endurance is tested at the South Pole. ... The South Pole has another crucial advantage over other telescope sites: Day and night work differently there. ... But a team of tiny astronomers at the South Pole could see you all day. ...
