full_context: Document 1: Major explorations after the Age of Discovery: Major explorations of Earth continued after the Age of Discovery. By the early seventeenth century, vessels were sufficiently well built and their navigators competent enough to travel to virtually anywhere on the planet by sea. In the 17th century Dutch explorers such as Willem Jansz and Abel Tasman explored the coasts of Australia. Spanish expeditions from Peru explored the South Pacific and discovered archipelagos such as Vanuatu and the Pitcairn Islands. Luis Vaez de Torres chartered the coasts of New Guinea and the Solomon Islands, and discovered the strait that bears his name. European naval exploration mapped the western and northern coasts of Australia, but the east coast had to wait for over a century. Eighteenth century British explorer James Cook mapped much of Polynesia and traveled as far as Alaska. In the later 18th century the Pacific became a focus of renewed interest, with Spanish expeditions, followed by Northern European ones, reaching the coasts of northern British Columbia and Alaska.
