The deepest human-made hole on Earth is in Russia’s Arctic North

Driven by Cold War competition, the Kola Superdeep borehole was a project in the 1970s to uncover the composition of the Earth by boring underground. The mission managed to go 7.6 miles into Earth’s crust, the deepest human-made hole on Earth.

Svalbard Brewery is the northernmost brewery in the world, located in a remote Arctic village where there are more polar bears than people.

Life during three months of polar night

In Norway's Svalbard archipelago, night reigns from November to January, as with many communities living within the polar regions. Contrary to popular assumptions about such places, many residents of the region describe the long darkness as peaceful, a time to slow down and draw nearer to neighbors and community. Read more on life in polar night, specifically in the Svalbard town of Longyearbyen, in this essay from a resident there.

Archaeological sites in present-day New Mexico containing stone tools and animal bones mark some of the earliest confirmed evidence of human life in North America.

The Viking landers were the first spacecraft to conduct experiments on Mars

NASA’s Viking 1 and 2 missions tested soils for signs of life, captured images, and studied the Martian atmosphere, revealing evidence of ancient water flow, volcanic soil, and a thin carbon dioxide atmosphere.

The Elizabethan pirate hired to find the Northwest Passage

This resource by the Canadian Museum of Natural History explores the life and adventures of Martin Frobisher, an Elizabethan pirate hired to find the then-fabled Northwest Passage, a path across the Arctic Sea that would've allowed for quicker trade between Asia and Eastern Europe. He ventured into arctic waters at least three times, returning to England each time with either fool's gold, captive natives, or fool's gold and captive natives.

Planetary exploration and the search for extraterrestrial life kicked off with Viking

NASA's Viking 1 and 2 missions revealed Mars' geological activity and potential for past life through their evidence of past surface water. Viking 1 held the record for the longest Mars surface operation until the Opportunity rover surpassed it in 2010.

Tracking the Isdal Woman

In 1970, a burnt body encircled by an odd assortment of items was found in a remote Norwegian valley. For nearly 50 years, the true identity of the woman escaped authorities who found she had traveled the country under many names. This podcast episode is the first in a 12-part series seeking to uncover the woman's identity and what happened in her final moments.

The US tried to buy Greenland in 1867 and after World War II

Denmark first took possession of the large, ice-covered island in the northern Atlantic in the 1700s. The local population is a mix of native Inuit, Norwegians (from the medieval era), and Danes, though the population is only 56,000. The US has seen the defensive and economic potential of the island for over 150 years.

Who was Gudrid the Far-Traveled?

Considered one of the greatest female explorers of all time, Gudrid the Far-Traveled counted among her in-laws Erik the Red and Leif Erikson. Traveling from Medieval Europe to North America via Iceland and Greenland, Gudrid became the first European woman known to have given birth in North America. This article details the pioneering achievements of medieval Europe's greatest female explorer.

The original article revealing Machu Picchu to the world

After first coming upon the ruins of Machu Picchu in 1911, Hiram Bingham’s subsequent expeditions were funded by Yale University, the Peruvian government, and $10,000 from a then-young National Geographic Society—in fact, it was the first archaeological grant that NatGeo ever issued. The magazine devoted its entire April 1913 issue, all 192 pages, to Bingham and his findings. You can read that issue in its entirety here.

As of 2025, humans have only dug 0.2% the way to Earth's center

The Kola Superdeep Borehole revealed two billion-year-old fossils and underground water, but the immense temperature and pressure prevented further tunneling. Beyond those depths, scientists know of Earth's interior by analyzing how seismic waves move.

Marie Curie's research in radioactivity made her the first woman to win a Nobel Prize

Overcoming social and academic barriers, Curie's realization that radiation resulted from an intrinsic property of atoms reframed scientific understanding of the phenomenon. Her subsequent work in discovering two new elements—polonium and radium—earned her a second Nobel Prize.

Records of Earth's magnetic field on the seafloor validated plate tectonics

Matching glacial, fossil, and rock records, mountain ranges, and continental shapes across oceans was insufficient evidence for continental drift. Precise measurements of magnetic minerals on the ocean floor revealed seafloor spreading, which could only be explained by moving landmasses.

How a pulsar's properties led to the discovery of the first exoplanets

In 1992, astronomers examining the radio waves emitted by PSR B1257+12 as it swept past detectors every 0.006219 seconds noticed occasional deviations at regular intervals. Further analysis revealed the existence of two planets beyond our solar system orbiting the neutron star, causing it to wobble and affecting pulsar timing.

Permafrost—soil, rocks, and sand that are held together by ice and remain frozen for at least two consecutive years—covers about 15% of the Northern Hemisphere's land area.

Instabilities in the polar jet stream can bring cold Arctic air southward

The polar jet stream marks the boundary between mid-latitude air and the much colder polar air, which are normally contained by the polar vortex—a ring of strong winds that circles the Arctic around 16 to 50 kilometers (10 to 30 miles) above the Earth's surface. Climate change may be responsible for "blocking patterns" that distort the jet stream, allowing polar air to leak into lower latitudes.

Viking established entry, descent, and landing methods for future planetary visits

The most significant engineering challenge was slowing the Viking lander, which would move through space at nearly 29,000 kilometers per hour before reaching Mars. This required the invention of supersonic parachute technology, which is still used today.

The missing continent that took 375 years to find

It took scientists 375 years to discover the eighth continent of the world, which had been hiding in plain sight all along. But mysteries still remain.

The movement of molten metal around Earth's inner core creates the planet's magnetic field, whose north and south poles do not align with the planet's geographic poles.

Why the Antarctic climate enabled British scientists to discover the ozone hole

In the Antarctic stratosphere, polar conditions facilitate the formation of polar stratospheric clouds, which allow chlorine compounds from chlorofluorocarbons to accumulate. In 1985, British Antarctic Survey scientists detected massive springtime losses over Antarctica, as accumulated compounds destroyed significant amounts of ozone once sunlight returned.
