Supernova dust in Antarctica snow could be 20 million years old: researchers

This illustration made available by the European Southern Observatory in 2014 shows shows dust surrounding a supernova explosion. Dust from a supernova, or an exploded star, has been found in snow in Antarctica, according to a new study.last week, could shed “invaluable” light on the history of our solar system and its place in the cosmos.

Researchers said that, within the last 20 million years, the Earth passed through a stardust cloud -- from one or more stars – and some of it remained in our blue planet’s atmosphere.Study co-author and nuclear astrophysicist Dominik Koll, of the Technical University of Munich, toldthat he’s “happy to actually see something which traveled billions of billions of kilometres through space and is millions of years old.

They let the snow melt and tested it with equipment sensitive enough to sift out different particles and anomalies, according to the American Physical Society'sMost of the iron in our universe is Iron-56 but cosmic explosions or nuclear bombs can make the atoms gain more neutrons, turning it into the rarer, heavier isotope Iron-60.

Was the snow at a different level 20 million years ago ? Hmm strange it’s like the climate has changed before on its own

Wow 25 years younger than Joe Biden

'We are so grateful': Parents of rescued 4-year-old share storyThe parents of a four-year-old B.C. boy who spent more than 30 hours alone in the wilderness say they can't begin to thank the emergency crews and volunteers who banded together to bring their son home safely. Yo thanks to all the search and rescue team they found the child. Bless and energy to all. Shame on these people. The mom left him unattended in a hot van, which he escaped from. He could have lost his life. I'm so over neglectful parents getting hall passes. Anything for a GoFundMe me, right? Again, I just want to say fuck these people. They are low life scum. Have some self respect, honor and cherish your children, and let people raise your child who will.
