crater caused by an asteroid collision
Scientists have finally determined the time of the crater that formed as a result of the Hayawatha planet in Greenland, and the time determined is much earlier than what was previously thought.
What is the largest impact crater on Earth?
A team from the Globe Institute at the University of Copenhagen and the Museum of Natural History in Denmark bombarded the site with laser beams.
This heated the soil until it started emitting argon gas, which they used to determine that the pit was 58 million years old.
What caused the Kara crater?
The zircon crystal of the rock was also analyzed at the same time in the Swedish Museum of Natural History using uranium-lead dating, and the same period came to light.
Nicole Krug Larson, a professor at the Globe Institute, said it was great to know her age.
We have been working hard to determine its age for seven years since it was discovered.
The collision released hundreds of thousands of times more energy than an atomic bomb and caused a pit 19 miles wide and 0.6 miles deep.
What are most craters in the solar system are caused by?
Space rocks are ruthless and, in light of everything, eagerly cratered considering a long history of contacts with various space rocks and possibly comets. Old impact pits on space rocks have beem contorted and erased by fresher impact openings. Obviously, sway events can confine space rocks into more unobtrusive pieces.
