Copy link for Radioactive Plutonium From Space Found in Pacific Ocean For the first time, scientists have discovered a rare form of plutonium on Earth. The radioactive element was lurking at the bottom of the Pacific Ocean — and an exploding star appears to have helped it get there. Why it matters: The discovery of this plutonium (plutonium-244) could help scientists understand how very heavy elements form, filling a gap in our understanding of the universe. "These are the elements where we are still in a mystery," lead researcher Anton Wallner told NPR. "We do not know exactly where th...

The rare radioactive plutonium isotopes dating back millions of years have led experts to question how it originated on the Blue Planet.

Far down in the periodic table you'll find a list of heavy elements born in chaos. The kind of chaos you might find in an exploding star perhaps, or a collision between two neutron stars.

Space-Born Plutonium Found on Floor of Pacific Ocean Subscribe Sputnik International https://sputniknews.com/science/202105141082884768-space-born-plutonium-found-on-floor-of-pacific-ocean/ Plutonium is a radioactive chemical element that was once synthetically produced by Glenn T. Seaborg, Edwin M. McMillan, J.W. Kennedy and A.C. Wahl in 1940. The element is proven to be a key source of nuclear energy, and has been used in several experiments from nuclear weapons to nuclear batteries. Researchers have reported that they have found rare forms of iron and plutonium along the bottom of the Paci...

Alien radioactive element prompts creation rethink 14 May 2021 The first-ever discovery of an extraterrestrial radioactive isotope on Earth has scientists rethinking the origins of the elements on our planet. The tiny traces of plutonium-244 were found in ocean crust alongside radioactive iron-60. The two isotopes are evidence of violent cosmic events in the vicinity of Earth millions of years ago. Star explosions, or supernovae create many of the heavy elements in the periodic table, including those vital for human life, such as iron, potassium and iodine. To form even heavier elements, suc...
