This 3D Simulation of a Supernova Needed 5 Million Hours of Supercomputing

When the largest stars in the Universe run out of fuel, they detonate as supernovae, collapsing inward and leaving behind a neutron star, black hole, or just wholly vaporizing.

When the largest stars in the Universe run out of fuel, they detonate as supernovae, collapsing inward and leaving behind a neutron star, black hole, or just wholly vaporizing. What’s happening inside the unfolding explosion is difficult to understand, and especially so for so-called exotic supernovae, the rarest and brightest types of stellar explosions.

But in recent years, large scale supernova observations have revealed rare types of cosmic explosions, one of which is tens to hundreds of times more luminous than ordinary supernovae, and the other lasts for extremely long periods of time. Dubbed as exotic supernovae, these rare events challenge and overturn previously established understanding of supernova physics.

However, modeling what happens during these massive explosions is quite challenging, and in this new paper, Ke-Jung Chen and team said that current models have mainly been confined to one-dimensional simulations.

Supercomputer simulation tackles problem of drug-resistant bacteriaA first-ever, atom-by-atom supercomputer simulation shows how antibiotics kill bacteria and illustrates other processes of the molecular machinery in living cells. The research opens fresh pathways to improving antibiotics, designing new ones to fight drug-resistant bacteria and developing vaccines for viruses such as SARS-CoV-2, which causes COVID-19.
