As ships explored the world from the Age of Sail through 20th century, mariners kept detailed navigation records using the Sun and stars. Scientists scoured these ship logs, many of which are preserved in European libraries, for clues about Earth’s magnetic field. The work, published in 2000, created the first-ever magnetic field map for the past 4 centuries.

About 3,600 years ago, a colossal volcanic eruption blew apart the Greek island Thera, now the popular tourist destination known as Santorini. Falling volcanic rock and dust buried the Bronze Age settlement Akrotiri, on the south side of the island, preserving multi-story buildings, frescoes, tools, furniture and food, until archaeological excavations uncovered them in the last century, much like the eruption of Vesuvius in 79 CE famously buried Pompeii and Herculaneum.

From 1946 to 1958, the United States military conducted more than 20 nuclear bomb tests at Bikini Atoll, an idyllic tropical island in the South Pacific Ocean. During the first of these tests, conducted in July 1946, the military anchored nearly 100 warships and submarines within Bikini’s large lagoon to see how a nuclear blast would affect a naval fleet.
