NASA plans to bring down the ISS at a location farthest from land

Point Nemo is located in the South Pacific Ocean at coordinates 48°52.6'S 123°23.6'W, approximately 2,688 kilometers (1,670 miles) from Ducie Island, Motu Nui, and Maher Island. The location has served as an underwater graveyard for hundreds of satellites and is expected to be harbor the International Space Station in 2030.

The world's quirkiest time zones

In contrast to telling time by physical signs like the sun or stars, cultural time relies on political agreement and standards. The convention of time zones arose due to transportation and communication advancements, and while many work just fine, some are pretty wild. Chief among those is the time zone of the uninhabited Baker and Howland Islands in the central Pacific, which results in a technical 26-hour day.

Just as landmasses have been divided into distinct nations, the world ocean has been divided into multiple oceans for various geographical, practical, and scientific reasons.

Railroads and long-distance communication led to the development of time zones, with Greenwich established as the prime meridian—the longitude of 0 degrees—due to British advancements in star mapping and navigation.

The art of 'undiscovering' phantom islands

No map of the Earth is perfect because each introduces inaccuracies in the shape, size, or orientation of landmasses and oceans by trying to flatten the planet's curved surface.

The geoid depicts what Earth would look like if not for tides and currents, given the planet's rotation and uneven gravitational field.

What is the Isle of Man in the Irish Sea?

The Isle of Man sits between Ireland to the west and Wales and England to the east. It is a self-governing British Crown dependency. This means it creates its own laws and collects its own taxes and currency, but is subject to the United Kingdom's defense systems and international treaties. Roughly 85,000 people live on the island, known as a tax haven for its attractive tax rates.

Scientists define sea level as the elevation to which water would settle on Earth's surface, given the planet's gravitational field and rotation.

Pheasant Island is controlled by both the Spanish and the French

The two-acre plot of land is a condominium—a territory shared by two countries. Pheasant Island (which, curiously, is not home to pheasants) is a holdover from the end of the Thirty Years' War between France and Spain, when it was designated as a neutral area dividing the countries.

Around 380 underwater cables power the Internet across the world.

On July 29, 1858, two steam-powered battleships met in the middle of the Atlantic Ocean. There, they connected two ends of a 4,000 kilometer (2,500 mile) long, 1.5 centimeter (0.6 inch) wide cable, linking for the first time the European and North American continents by telegraph.

How did Polynesian wayfinders navigate the Pacific Ocean?

Ancient Polynesian navigators used the sun, moon, stars, clouds, currents, and more to sail the seas. People of Southeast Asia began their voyages to the region now known as Polynesia in roughly 1500 BCE. They would settle a vast area of 15 million square miles, including hundreds of islands, moving from islands due to overpopulation or war. Such voyages dwindled in 1300 CE as societies became more rooted.

Grosse Île, the quarantine island of the Port of Quebec

As tens of thousands of Irish emigrated to North America to escape the Great Famine in the mid-19th century, many port cities set up quarantine areas amid an epidemic of cholera. In Quebec City on the St. Lawrence River, one island became a mass graveyard where over 3,000 Irish immigrants died over a decade as they waited in quarantine. Listen to the history here.

Conservative estimates suggest that 21.1 billion tons of polymetallic nodules exist in this abyssal plain, but about 90% of the species in the area are unknown to scientists.

What is a singularity?

It's hard to imagine a singularity, which are described as an infinitely tiny point, created by gravity, until it has zero volume. The definition feels impossible, though perhaps not at the center of a black hole or at the beginning of the universe. Even then, singularities may be something else entirely. Singularities are a mathematical quandary that challenge us to better understand physics and the universe.
