This isn't the first time an iceberg has sloughed off Antarctica.

Antarctica is about to lose an iceberg 30 times the size of Manhattan as two cracks converge — and it could cripple a British research station

NASA is tracking two converging cracks in Antarctica's Brunt Ice Shelf. When they meet, an iceberg 30 times the size of Manhattan could float away.
A gigantic cavity nearly 1,000 feet tall is growing at the bottom of Thwaites Glacier in west Antarctica.

There’s a cavity underneath Antarctica that’s two thirds the size of Manhattan — a sign ice sheets are melting faster than we though...

Nearly 14 billion tons of ice have melted underneath Antarctica's Thwaites Glacier, leaving an almost Manhattan-sized cavity beneath the surface.
The SALSA Drill Team uses McMurdo Station to prepare for its work drilling into Mercer Subglacial Lake.

In a lost lake 3,500 feet under the Antarctic Ice, scientists just found the carcasses of tiny creatures

Scientists found the bodies of tiny animals and plants in sediment pulled up from a lost lake located 1 kilometer under the Antarctic ice.
An illustration of asteroids careening toward northern Greenland.

A 5-billion-ton iron meteorite once slammed into Greenland — and scientists found its Paris-size crater under the ice

When a team of scientists studied a new map of Greenland's bedrock, they found a 16-mile-wide depression that looked like a gigantic blast crater.
Vast glaciers in West Antarctica seem to be locked in an irreversible thaw linked to global warming that may push up sea levels for centuries.

Scientists think a giant artificial wall propped up under Antarctica’s ice sheets could stop catastrophic sea-level rise

If the sheets of ice sitting atop Antarctica and Greenland were to collapse, the rates of sea-level rise could skyrocket, destroying trillions of dollars' worth of property and infrastructure. To prevent or slow these floods from washing over cities, we may want to build huge walls under the sheets.

There’s some surprising news in a NASA study on Antarctica’s ice sheet

A surprising new NASA study has some positive news for Antarctica, but that's not the whole story.
