JWST finds the compact object in SN 1987A

node

Infrared integral-field spectroscopy with JWST detected narrow argon and sulphur emission lines confined to the centre of the SN 1987A remnant. Photoionisation modelling indicates the gas is being ionised either by ultraviolet and X-ray radiation from a hot cooling neutron star or by a pulsar wind nebula. After thirty-seven years in which the expected remnant had never been seen, the object the neutrino burst implied was finally located; which of the two ionisation mechanisms dominates is still argued.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
