Scientists have found an “alien” grain of dust inside a meteorite in Antarctica that survived the birth of our solar system. It is believed that the tiny speck of material was created by a distant star as it was obliterated in a huge explosion. Experts reckon that the ‘grain’ found can give more insights on how everything that rotates and revolves around Earth, our Sun, and also shed light on how the solar system was born.

“As actual dust from stars, such presolar grains give us insight into the building blocks from which our solar system formed,” said Dr. Pierre Haenecour, lead author of the study. Also Read - Giant Asteroid As Tall As Burj Khalifa To Make Near-Earth Approach on November 29, Is it Dangerous?

“They also provide us with a direct snapshot of the conditions in a star at the time when this grain was formed,” he added. Also Read - Chhath Puja 2020: Know History And Significance of The Festival Dedicated to The Sun

The meteorite was initially found and collected by NASA and then studied by scientists at the University of Toronto. The scientists tiny ‘grain’ is stardust and named it LAP-149. It is being said that the Stardust was formed 4.5 billion years ago after the death of a violent star known as a supernova explosion.

“This kind of research, it’s part of a much larger debate of how life started on Earth,” said University of Toronto scientist Professor Jane Howe.

“We all care about who we are and where we came from”.
