Scientists have stumbled upon life under 3,000 feet of ice in Antarctica.
They found two types of unidentified animals, where they thought nothing could live.
Their next step is to find a way to get close enough to identify the creatures.
Scientists have found life buried under 3,000 feet of ice in Antarctica, challenging the assumption that nothing could live under such conditions.

Scientists previously thought that Antarctica's cool temperatures and lack of light and food made it impossible for living creatures to thrive.
The creatures were found attached to a boulder in the arctic seas under the Filchner-Ronne ice shelf. Experts from the British Antarctic Survey drilled through 2,860 feet of ice before making the discovery.
"The area underneath these ice shelves is probably one of the least-known habitats on Earth," said Huw Griffiths, one of the scientists who made the discovery, in a Twitter video.
"We didn't think that these kinds of animals, like sponges would be found there."
It's more than 579,000 square miles, but little has been explored under the ice.
Enormous icebergs occasionally break off the ice shelves and drift away. One of these icebergs threatened to crash into a breeding ground for sea lions and penguins in December.
They were drilling through the ice sheet to collect samples from the seafloor. Instead, their camera hit a boulder. When they reviewed the camera's footage, it revealed the discovery.
"Never in a million years would we have thought about looking for this kind of life, because we didn't think it would be there," Griffiths told The Guardian.
The video reveals two types of unidentified stationary animals, shown here in a video from the British Antarctic Survey. The animals in red seem to have long stalks, whereas another type of animal, highlighted in white, looks more like a round sponge-like animal.
These animals have been found approximately 160 miles from the open sea.
"Our discovery raises so many more questions than it answers, such as how did they get there?" Griffith said in a press release. "What are they eating? How long have they been there?"
The scientists said their next step was to understand whether the animals were from a previously unknown species.
"To answer our questions we will have to find a way of getting up close with these animals and their environment," Griffiths said.
Life at research stations in Antarctica is not easy, as Insider's Monica Humpfries reported.
