Dr Janaina Avila contributed to a paper in the Top 10 in science in 2020!  SHRIMP data helped to constrain the oldest material on Earth.

Exploding stars form gas and dust that is spread through space; a modern example of this process is the Egg Nebula (shown).  Dust from stars that exploded before our solar system formed are found in some meteorites, including the Murchison meteorite from Victoria, Australia. This type of dust makes up so-called presolar grains.  Presolar grains are dated with a variety of methods including SHRIMP.
