A mysterious island that popped up from nowhere is said to be brimming with life.
After appearing around three years ago in the Southern Pacific Ocean, it is now covered in vegetation and birds.
Located in the ocean surrounding Tonga, the island is also covered in a strange sticky mud according to NASA scientists.
Dan Slayback, of Nasa’s Goddard Space Flight Center , went to visit the remote island to learn more about its form.
He was joined by scientists and students from the Woods Hole’s Sea Education Association (SEA) Semester’s South Pacific cruise.
The team, who previously studied the island via satellite, visited the land mass in person in October and highlighted their findings in a blog post.
The island was caused by a volcanic eruption and is one of only three that have erupted in the last 150 years.
It "survived the ocean’s eroding waves longer than a few months," according to the post.
Mr Slayback writes the sand is like pea sized gravel and can be painful as it gets underfoot.
He wrote: "It’s pretty flat, but there’s still some gradients and the gravels have formed some cool patterns from the wave action.
"And then there’s clay washing out of the cone. In the satellite images, you see this light-colored material.
"It’s mud, this light-colored clay mud. It’s very sticky.
"So even though we’d seen it we didn’t really know what it was, and I’m still a little baffled of where it’s coming from because it’s not ash."
The team also tried to find out the elevation of the island as well as picking up small samples and minerals.
Researchers are now trying to establish how long the island will survive as erosion is already starting to happen.
