Kilonova explosions created when neutron stars collide and merge are perfectly spherical, not flattened discs as previously expected, a new study suggests.
When neutron stars collide, they produce a powerful explosion. The first collision that astronomers have clearly observed has shown that, contrary to expectations, the explosion was perfectly spherical. The formation of the spherical shape is still a mystery to researchers, but the discovery could open new doors in fundamental physics and the determination of the age of the universe.
