Scientists to Find Radioactive Dust from an Ancient Supernova in Antarctica  


We have recently heard that radioactive dust from a supernova landed in Antarctica from a star that exploded into a supernova million of years ago. There, it eventually got buried under thousands of pounds of snow.   

They did a lot of excavating  

After the process of excavation took place in Antarctica, scientists hoped that, by studying the dust, they would get new secrets about the cosmic environment that surrounds our solar system. This is what we have heard from the lead researcher, whose name is Dominik Koll. He is a doctoral candidate at the Australian National University. If they study an ancient cosmic explosion, they get a better chance at understanding the history of our galactic surroundings. It is very interesting to walk through it.   

It is all published in the journal Physical Review Letters  

Koll’s team got rid of the snow in their labs in order to collect the specks of space dust. Then, they proceeded to analyze it to see if they can find radioactive isotopes. This comes according to the research published in the journal Physical Review Letters 

What did they find?  

They found more radioactive isotopes than they would have ever if the dust had just passed through everyday cosmic rays on their way to Earth. The team cited their past work, in which they talked about a supernova that had deposited iron into the solar system in the last 1.5 to 3 million years. Then, the Earth probably traveled the remnants of that explosion, which helped scientists get a better idea of the composition of the Milky Way.
