A giant slab of ice bigger than the Spanish island of Majorca has sheared off from the frozen edge of Antarctica into the Weddell Sea, becoming the largest iceberg afloat in the world, the European Space Agency said on Wednesday.

The newly calved berg, designated A-76 by scientists, was spotted in recent satellite images captured by the Copernicus Sentinel-1 mission, the space agency said in a statement posted on its website with a photo of the enormous, oblong ice sheet.

Its surface area spans 4,320 square km (1,668 square miles) and measures 175 km (106 miles) long by 25 km (15 miles) wide.

By comparison, Spain's tourist island of Majorca in the Mediterranean occupies 3,640 square km (1,405 square miles). The US state of Rhode Island is smaller still, with a land mass of just 2,678 square km (1,034 square miles).

The enormity of A-76, which broke away from Antarctica's Ronne Ice Shelf, ranks as the largest existing iceberg on the planet, surpassing the now second-place A-23A, about 3,380 square km (1,305 square miles) in size and also floating in the Weddell Sea.

Another massive Antarctic iceberg that had threatened a penguin-populated island off the southern tip of South America has since lost much of its mass and broken into pieces, scientists said earlier this year.

One of NASA’s two stuck astronauts got a much welcomed change of scenery Thursday, stepping out on her first spacewalk since arriving at the International Space Station more than seven months ago.

Suni Williams, the station's commander, had to tackle some overdue outdoor repair work alongside NASA's Nick Hague. They emerged as the orbiting lab sailed 260 miles (420 kilometers) above Turkmenistan, The AP reported.

“I'm coming out,” Williams radioed.

Plans called for Williams to float back out next week with Butch Wilmore. Williams and Wilmore launched aboard Boeing’s new Starliner capsule last June on what should have been a weeklong test flight.

But Starliner trouble dragged out their return, and NASA ordered the capsule to come back empty. Then SpaceX delayed the launch of their replacements, meaning the two won’t be home until late March or early April — ten months after launching.

It was the first spacewalk by NASA astronauts since an aborted one last summer. U.S. spacewalks were put on hold after water leaked into the airlock from the cooling loop for an astronaut's suit. NASA said the problem has been fixed.

This was the eighth spacewalk for Williams, who has lived on the space station before.
