Solar System formed from “poorly mixed cake batter,” isotope research shows

Researchers have discovered that primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. This suggests that the Solar System was formed from a 'poorly mixed cake batter' of materials, with some planets receiving a unique blend of elements from distant sources.

Study sheds light on stellar origin of 60Fe

Researchers have made significant progress in understanding the stellar beta-decay rate of 59Fe, which is essential for predicting the yield of 60Fe in massive stars. By measuring this rate, they eliminated a major nuclear uncertainty and found that the yield of 60Fe is 40% less than previously predicted.

Primordial black holes may have helped to forge heavy elements

Tiny primordial black holes could have destroyed neutron stars from the inside out, leading to the ejection of dense neutron-rich material that formed heavy elements like gold and uranium. This process would also explain several long-standing mysteries in the universe, including Fast Radio Bursts and positron emissions.
