Plasma Patch Atlas
High above the surface of the Earth, flow giant, invisible clouds of charged gas that can degrade radio transmissions, disrupt GPS Signals and play havoc with other communications and navigation systems. But they're not always showing up when scientists predicted. This year geophysicist Alex Chartier traveled across Antarctica to figure out what's going on in Earth's upper atmosphere.

The Flight of X-Calibur
Antarctica can be a double-edged sword for astronomers: conditions there are some of the best in the world for observing the heavens, but the harshness of the place can be hard on equipment. In December 2018, astronomers who launched the x-ray telescope "X-Calibur" to study neutron stars and black holes got a taste of that contrast.

Listening to Rock Music
Rocks are cracking up all over Antarctica's McMurdo Dry Valleys. Though it may take hundreds of thousands, or even millions of years, the slow but inevitable processes of weathering eventually reduce all rocks into sand or even clay.

Digging For Fishies
The mountains of Antarctica may seem an unlikely place to find fish, but they were exactly what a team of paleontologists working along the edge of the Polar Plateau last winter were looking for. In a region now defined by dry rocky terrain poking up through vast sheets of thick ice, the five-member team spent much of December and January scouring the exposed landscape for the remains of ancient fish.

Icefin Tests the Waters
Navigating a robot through the frozen ocean's frigid waters was all in a day's work for the RISE UP science team. From their makeshift mission control in a small fish hut, the researchers maneuvered their underwater vehicle through the seawater below.

The Dry Valleys' Briny Deep
Hunting for groundwater has come a long way from divining rods in the days of yore. This past austral summer, scientists in Antarctica used a sophisticated and highly sensitive instrument to look for water in one of the continent's driest regions.

The First Wave of the "Thwaites Invasion"
The U.S. and U.K.-funded International Thwaites Glacier Collaboration (ITGC) officially kicked off its science field research in January, when four researchers and their support teams set foot on a remote, fast-melting glacier in West Antarctica, establishing a beachhead for an unprecedented international project to determine the glacier's fate.

An Ecosystem Grows in Antarctica
Antarctica's native microorganisms are a hearty bunch, able to eke out a living on the planet's coldest, highest, driest, windiest and emptiest continent. But the region wasn't always quite as hospitable as it is today.
