Ultimately, a believable rationalization for the Milky Means’s heavy parts

Till just lately it was thought neutron star mergers had been the one manner heavy elements (heavier than Zinc) could possibly be produced. These mergers contain the mashup of the remnants of two huge stars in a binary system.

However we all know heavy parts had been first produced not lengthy after the Huge Bang when the universe was actually younger. Again then, not sufficient time had handed for neutron star mergers to have even occurred. Thus, one other supply was wanted to clarify the presence of early heavy parts within the Milky Means.

The invention of an historic star SMSS J2003-1142 within the Milky Means’s halo — which is the roughly spherical area that surrounds the galaxy — is offering the primary proof for an additional supply for heavy parts, together with uranium and presumably gold.
