Venus transit to be watched across the world

Skywatchers on seven continents, including Antarctica, will be able to see all or part of the Venus transit:

  • Should only be observed with telescopes outfitted with solar filters to protect the eyes
  • Internet will be a hub of activity, with live video and pictures from an armada of space- and ground-based observatories
  • Even astronauts aboard the International Space Station are joining in the event

Space station flight engineer Don Pettit said: "I've been planning this for a while," in a NASA interview. "I knew the transit of Venus would occur during my rotation, so I brought a solar filter with me."
