New study discovers ancient meteoritic impact over Antarctica 430,000 years ago
A research team of international space scientists, led by Dr Matthias van Ginneken from the School of Physical Sciences‘ Centre for Astronomy and Planetary Science, has found new evidence of a low-altitude meteoritic touchdown event reaching the Antarctic ice sheet 430,000 years ago.
Extra-terrestrial particles (condensation spherules) recovered on the summit of Walnumfjellet (WN) within the Sør Rondane Mountains, Queen Maud Land, East Antarctica, indicate an unusual touchdown event where a jet of melted and vaporised meteoritic material resulting from the atmospheric entry of an asteroid at least 100 m in size reached the surface at high velocity.
