Recent scientific studies have brought to light significant findings related to Antarctica and asteroid impacts. Researchers drilling ice cores in Antarctica, as reported by CNN, have discovered alarming evidence of rapid ice loss in the past, specifically abrupt Holocene ice loss in the Weddell Sea Embayment, as indicated by Mackenzie Grieman and colleagues. This adds to the understanding of Antarctic ice dynamics and climate change. Moreover, samples from asteroid Bennu have led to speculation that it may have been part of a watery protoplanet. In a related context, there's evidence suggesting an asteroid airburst occurred over Antarctica between 2.3 and 2.7 million years ago, potentially the oldest known of its kind. This event is thought to have resulted in a destructive plume that scorched the Earth. Additionally, a model-based study published in Science Advances by Yale researchers proposes that large asteroid impacts could have triggered 'snowball' Earth conditions when the background climate was already cold, such as during ice ages.

Bits of rock found in Antarctica may point to the oldest known asteroid “airburst” — a mid-air disintegration that likely torched the ground with a destructive plume. https://t.co/UxanUwINt6
