Astronomers have spotted Strontium in the aftermath of a collision between two neutron stars. This is the first time a heavy element has ever been identified in a kilonova, the explosive aftermath of these types of collisions. The discovery plugs a hole in our understanding of how heavy elements form.

What? No.
First of all, it’s already been proved that Type Ia supernovae can’t be the result of neutron star collisions – this type of collision occurs so infrequently that we’ll never see one.
Second, we already know that heavy elements come from star collapse supernovae, Type II. And there’s no reason on Earth (deliberate malaprop) why heavy elements couldn’t also form from white dwarf supernovae Type Ia.
So, this result is a very interesting observation that proves that heavy elements are formed when white dwarves (second deliberate malaprop) go supernova.
Oh, and there’s no such thing as a “kilonova”, prove me wrong.

Oops, we can see neutron star collisions, as in a specific type of gravitational wave, but they’re rare even out to the edges of the observable universe.
