A half-melted hunk of iron-rich rock found in Uppsala, Sweden, is part of a meteorite that fell there in November 2020. 

The lumpy meteorite is about the size of a loaf of bread and weighs around 31 pounds (14 kilograms), according to the Swedish Museum of Natural History. It was once part of a larger space rock, probably weighing more than 9 tons (8.1 metric tons), that created a dramatic fireball over Uppsala on Nov. 7. 

After that impact, scientists at the Swedish Museum of Natural History calculated the likely landing site and found some small fragments of iron meteorite near the village of Ådalen, according to a museum statement. The fragments were only about 0.1 inches (3 millimeters) long, but the investigation also turned up a boulder and a tree root that had clearly been hit by something heavy.

Stockholm geologists Andreas Forsberg and Anders Zetterqvist headed back to the site and found a much larger piece — likely the one that smashed the boulder. The piece was about 230 feet (70 meters) from the area where the fragments were found, partially buried in moss. One side is flattened and cracked, likely from the collision, and the meteorite is pockmarked with circular depressions. These depressions are common in iron meteorites, according to the museum, and they form when the space rock partially melts during its passage through the atmosphere.
