The cornerstone for Tycho Brahe's Uraniborg observatory is laid on the island of Hven.
On August 8, 1576, the foundation stone was laid for Tycho Brahe's Uraniborg observatory on the island of Hven.
Danish astronomer Tycho Brahe laid the cornerstone of Uraniborg on Hven in 1576. The observatory was the first purpose-built research facility in Europe. Brahe designed its instruments to achieve unprecedented precision in astronomical measurements. Uraniborg became a hub for observing stars, planets, and comets. Its innovative design included a laboratory for alchemical experiments. Patrons of the arts and sciences visited the estate at Brahe's invitation. The data collected here later enabled Johannes Kepler to formulate his laws of planetary motion. Uraniborg remains a symbol of the Scientific Renaissance.

John Davis enters Cumberland Sound in search of the Northwest Passage.
In 1585, explorer John Davis entered Cumberland Sound during his search for the Northwest Passage.
English navigator John Davis embarked on an Arctic expedition in 1585 to find a northerly route to Asia. During this voyage, he discovered and sailed into Cumberland Sound off the coast of present-day Nunavut. Davis charted parts of Baffin Island's coastline, making valuable geographic observations. Ice conditions forced him to turn back after limited exploration. His account of the journey expanded European knowledge of the Arctic region.
