The half-melted mass of iron-rich rock found in Uppsala, Sweden, is part of the meteorite that fell there in November 2020.
According to the Swedish Museum of Natural History, the rugged meteorite is the size of a loaf and weighs about 31 pounds (14 kilograms). It was once part of a larger space rock that weighed perhaps more than 9 tons (8.1 metric tons), Dramatic fireball Over Uppsala on November 7th.
After that influence, scientists at the Museum of Natural History in Sweden calculated possible landing sites and found small pieces of iron meteorite near the village of Ådalen. According to a statement from the museum.. The debris was only about 0.1 inches (3 millimeters) long, but investigations also found rocks and tree roots that hit apparently heavy objects.
Stockholm geologists Andreas Forsberg and Anders Zetterqvist returned to the scene and found a much larger part. Probably the one that broke the rock. It was about 230 feet (70 meters) from where the debris was found and was partially buried in moss. Probably due to a collision, one side is flattened, cracked, and the meteorite has a circular depression. According to the museum, these depressions are common in iron meteorites and are formed when cosmic rocks partially melt as they pass through the atmosphere.
“This is the first sure example of a new iron meteorite that has fallen in our country,” said Dan Holtztam, curator of the Museum of Natural History in Sweden. Said in a statement.. It is also the first time in Sweden that meteorite debris associated with an observed fireball has been recovered for 66 years.
“We know it’s an iron meteorite, so we can fine-tune the simulation of the fall of the meteorite,” said Eric Stempels, an astronomer at Uppsala University, in a statement. Originally, it is the largest existing work after the heavy space rock of about 9 tons. Perhaps there are small debris left in the area. “
Iron meteorite The second most common type of meteorite After a stony meteorite, it will land on Earth.They come from the core of planets and asteroids, which means they can hold clues to their formation. Solar system..
It is known that some iron-rich meteorites are lurking. Minerals not found on earth..Other types of meteorites Contains complex organic compounds, Perhaps a component of life hints at how it first landed on this planet.
