Un investigador suizo halla un espectacular meteorito en la Antártida
“Finding a meteorite that’s larger than a fist is extraordinary,” said ETH Zurich earth scientist Maria Schönbächler, who was part of the Antarctica mission. Most meteorites found weigh only about 20 grams, she said.
A meteorite is a solid piece of debris that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.
“Meteorites are used for planetary exploration,” Schönbächler said. This is because the number of meteorites available for research is extremely limited. In Switzerland, for example, only 11 meteorites have been found since 2018. “That’s why 7.6kg more to analyse is a lot,” she explained.
The research team searched for meteorites in Antarctica from December 2022 to mid-January 2023. Using satellite images and GPS coordinates, they explored the potential of several areas. “Antarctica is suitable for meteorite finds because the black stones are easily visible on the white snow,” Schönbächler said.
She said that due to the migration of the glaciers, new meteorites would continue to be uncovered in the million-year-old ice. In addition to the large meteorite, the researchers also found several smaller ones.
In Brussels
The meteorite was transported frozen to Brussels, where it is being thawed under controlled conditions at the Royal Belgian Institute of Natural Sciences. “There are metals in a meteorite that can rust quickly,” Schönbächler explained. To avoid this, the water has to be drained off immediately during thawing.
Once thawed, the meteorite is precisely dated, she said. “We assume it’s about four-and-a-half billion years old.” The meteorite will then be available for further scientific studies.
