The supernova SN2020 jfo is a type 2 nova. Type II supernovae like 2020jfo involve the sudden and violent collapse of a supergiant star when its nuclear fuel gas tank hits empty. With no heat and pressure in the core to battle back the crushing hand of gravity, the star implodes. The infall rebounds at the core, creating a shock wave of such ferocity that it rips through the star and blows it to bits in a titanic explosion 100 million times brighter than the Sun. No wonder we can see these things in our backyard telescopes (source Sky & Telescope)!
