A pulsar is found inside the Crab Nebula

node

The detection of a 33-millisecond pulsar at the centre of the remnant of the 1054 supernova closed the chain that had been open since 1934: a recorded historical explosion, an expanding remnant, and a neutron star at its centre with a rotation period short enough to require an object only kilometres across. It also explained why the nebula still glows - the pulsar's rotational energy, measurably decreasing, powers it.

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

  35. Evidence
  36. Supports the description of the Crab Nebula as a pulsar-wind-powered remnant with a rotation period near 33 milliseconds. The review was not fetched; the 33.392 ms period and the ~6,500 light-year distance come from reference summaries and are quoted as approximate.
