Radio Astronomy co-hosts Diego Casanova and Brianna Smart explain the technology that astronomers use to sort though the 120 gigabytes of Hubble images a week. With Hubble having so many images they had to find an easy way to sort them.They used modern day “Facial Recognition” software, but for planets! The software is in charge of finding three phases of the planets: Pre-Blue Nugget, Blue Nugget, and Post-Blue Nugget. The Blue nugget phase is the compact star-forming phase. Having these three phases makes it easier for the sorting to occur. In both, the simulated and observational data, the program found that the “blue nugget” phase only occurs in galaxies with masses in a certain range. After the “Blue Nugget” phase they become “Red Nuggets”.
