Chasing Aerosol Ghosts
For a big mass of air, the Earth's upper atmosphere is a complicated place. The changing seasons cause temperatures and pressures to rise and fall, altering the characteristics of the planet's atmospheric layers, sometimes dramatically.

Where the Ice Layers Grow
Hunting for the perfect patch of ice can be a herculean task. Knut Christianson, of the University of Washington, spent three weeks with his research team in a barren and remote part of Antarctica, scouring the landscape for the perfect spot.

Insects in the Extreme
Scientists are taking a close look at Antarctica's largest land animal. It's a small insect called the Antarctic midge, and they don't grow much bigger than a fingernail.

Pumping Iron
Cold, hard iron is on the move. Particles of the ferrous metal are trickling into Antarctica's oceans, and marine algae are gobbling it up.

Facing the Ultimate Acid Test
Some of the Southern Ocean's smallest animals are facing big challenges. The once-exceedingly stable Southern Ocean around Antarctica is warming, and as it absorbs carbon dioxide from the atmosphere, it is also growing more acidic.

Stringing Together More Neutrino Detectors
The biggest experiment at the South Pole is getting a significant upgrade. Over the next three years, IceCube, the neutrino detector located at the South Pole, will be getting numerous new detectors added to its core. It's the biggest upgrade to the IceCube detector since its completion in 2010.

Masses of Mosses
As the continent warms, Antarctica is getting greener. Plants are taking hold where glaciers once covered the landscape. Moss in particular is sprouting up in new spots where it had been previously inhospitable. While moss isn't a new arrival to the continent, its spread could mean big changes for the ecosystems of Antarctica.

A Seal Grows In Antarctica
Weddell seals thrive in some of the coldest conditions on the planet, but scientists aren't quite sure why they don't freeze when they're first starting out.

Hunting For the Oldest Ice
For scientists, ice cores are an indispensable window into the past. A research team using ancient ice recovered from Antarctica, announced recently that they'd identified some of the oldest air samples ever discovered, as far back as 2 million years ago, and that they're going back for more.

Larvae La Vida Loca
As oceans warm around the world, the creatures that live in them are feeling the effects. In regions like the Southern Ocean surrounding Antarctica, which has been unchanged for millennia, researchers worry that even small fluctuations in water temperatures can have major effects on the marine ecosystem.

SALSA Part I: Scratching the Surface
A team of researchers and drilling engineers recently spent six weeks in West Antarctica carefully drilling through nearly a mile of ice to study Mercer Subglacial Lake. This body of water is buried under an ice stream, and likely hasn't seen the light of day for at least thousands and possibly hundreds of thousands, of years.

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.
