Supernovae, categorized as Type I (low hydrogen) and Type II (high hydrogen), produce varying abundances of heavy elements. Type Ia supernovae, resulting from thermal runaway in white dwarfs, are rich ...
Heavy duty: artist’s impression of a kilonova releasing r-process elements into the cosmos. (Courtesy: ESO/L Calçada/M Kornmesser) The mystery of where heavy elements such as gold and silver come from ...
Are we made of stars? This video segment adapted from NOVA features scientists studying light emissions from exploding stars, called supernovas. Their observations and analyses can tell us the origin ...
Scientists have made an exciting breakthrough in understanding how the universe creates the ingredients needed for life. A joint mission by NASA and the Japan Aerospace Exploration Agency (JAXA) has ...
Astronomers have spotted AT2025ulz, a rare dual explosion — a supernova and a kilonova — that may be the first-ever observed ...
Hydrogen and helium formed shortly after the Big Bang. Stars create elements lighter than iron through nuclear fusion. Supernovae produce elements heavier than iron via the r-process. Neutron star ...
Researchers have found white dwarf stars with masses close to the maximum stable mass (called the Chandrasekhar mass) are likely to produce large amounts of manganese, iron, and nickel after it orbits ...
So you like TNW? Then join our upcoming online event, TNW2020, you don’t want to miss it. Neutron star collisions were thought to make much of the gold in the Universe, but something else is making a ...
XRISM observations of Cassiopeia A reveal abundant chlorine and potassium, showing supernovae can forge these life-linked elements and clarifying their cosmic origins. (Nanowerk News) "Why are we here ...
Hidden within Cassiopeia A, the youngest known exploded star in our galaxy, astronomers have found surprisingly high levels of chlorine and potassium. These elements carry an odd number of protons in ...
For hundreds of millions of years, a pair of neutron stars – the burned-out cores of once massive stars – spiraled closer and closer together until finally colliding in a tremendous explosion known as ...
Although the periodic table is filled with elements, nuclear fusion at the center of stars can only produce elements with atomic masses lower than iron—after than, neutron captures processes known as ...
