Thwaites Glacier—which is about the same size as Florida—contains enough ice on its own to raise global sea levels by about two feet if it all melts.
The snow contained substantial quantities of dust-enriched with iron-60—which isn't naturally produced on our planet.
"The new species is one of the largest fossil penguins described so far and one of the very few giant penguins," said researcher Gerald Mayr.
IceCube searches for neutrinos—invisible, nearly massless subatomic particles which rarely ever interact with normal matter.
Two mysterious plankton blooms appeared off the coast of Antarctica in 2014 and 2015.
As the Earth's climate warms, melting ice sheets are expected to lead to an increase in global sea levels.
The ice-free zone appeared in 2017 and grew to more than 30,000 square miles.
Unusual warm winds have led to a spike in late-season surface melt at the ice shelf.
Researchers said that green icebergs could be playing a key role in delivering nutrients around the ocean.
The bird has somehow survived, despite a coat that makes it a target for predators.
Until around three years ago, the cavity contained an estimated 14 billion tons of ice.
Antarctica contains enough water to raise global sea levels by 190 feet, according to NASA.
Colin O'Brady endured temperatures as low as -40 Celsius and winds that can reach up to 200 miles per hour.
Scientists said there might be many more of these localized hot spots than previously thought.
The European Space Agency's gravity mapping satellite has provided a new view of the landscape beneath the ice.
Sergey Savitsky attacked a colleague he had been living with for six months.
Also known as the deep sea swimming cucumber, the creature was filmed by Australian researchers.
The satellite was successfully launched from California's Vandenberg Air Force Base.
Scientists propose radical geoengineering plan to slow down the collapse of ice sheets.
"Humankind needs to do more" to protect penguins.
The iceberg, which weights more than 1 trillion tons, broke off from Antarctica's Larsen C Ice Shelf in July 2017.
"It has become clear that microplastics are dispersing all over the world—in the water column, sediment, and marine animal diets—even reaching as far south as the pristine environments of Antarctica."
When the Pine Island Glacier melts, it could trigger even more ice to melt and raise global sea levels.
The results could transform scientists' understanding of how low temperatures can go on the Earth's surface.
As the U.S. and the rest of the Northern Hemisphere mark the summer solstice, Australia, Antarctica and others are in the middle of winter.
