Common chemical elements are created in stars like our sun. But heavy elements, like iron, are thought to form in massive stars that explode and spew material — though it might be more complicated.

Remnants of a supernova called Cassiopeia A, located in our galaxy about 11,000 light-years from Earth. Scientists have long thought that supernovae were responsible for the creation of the heaviest elements, but new research suggests other types of stellar events may also be in play. (NASA / CXC / RIKEN / T. Sato et al.; NuSTAR: NASA / NuSTAR) by Alex Fox/Smithsonianmag.com Scientists studying a hunk of Earth’s crust gathered from deep in the Pacific Ocean have discovered traces of rare form...

       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 (Pu-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...

Here are some of the most interesting research papers to have appeared in top science journals last week.

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 ...

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 youll 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. Research...

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.
