This is not the first time the world’s coldest and most remote continent has surprised researchers. In 2019, US scientists unearthed a small piece of a comet, which was stacked inside an asteroid, that hit our planet billions of years ago.
An international group of scientists has discovered a speck of stardust, which researchers estimate arrived on our planet 4.5 billion years ago – when Earth was about 400 million years old and around the time the Solar System was forming. According to the findings of their study, published in the American Physical Society’s weekly journal, Physical Review Letters, the scientists were astounded to find the dust which was shaped like a croissant.
