390 times a second? Imagine standing on it (assuming you were impervious to gravity).

| anonymousgamer, you missed the highlight of the discovery. It isn't newsworthy because of the pulsar's fast rotation; there are many known pulsars with faster rotational periods.
This discovery is remarkable because of the orbital period. The binary pair completes one orbit every 93 minutes.

| Well, pulsars are just neutron stars, and there are neutron stars in SE.

| Well I dont think they are the same pulsars spin faster then neutron stars so that does make them differant.
Or maybe pulsars somehow turn into neutron stars.

That's pretty much the only difference. They also give off more radiation, but they are essentially just fast spinning neutron stars.

No, why do you say this?

| All pulsars are neutron stars, but not all neutron stars are pulsars. What makes a pulsar a pulsar is that it strongly emits directed EM radiation, which appears to pulse over short periods due to rotation (classic 'rotating light house beam' model.)
What powers these beams is not simply the rotation, however. The beams carry away energy, but total energy is conserved. So they can't power their beams by rotating at a constant rate. That would violate physics. It is the slowing of the rotation -- the loss of angular momentum -- that does the trick. They can also be powered by decaying magnetic field. So, in general, it is the younger neutron stars that tend to be pulsars, and pulsars tend to decay into neutron stars after sufficient time. (Though they can be maintained or even 'spun up' by accreting from a companion star.)
The reason you don't see pulsars in SpaceEngine is that there is not yet a system in place that enables you to determine the difference. (Similar situation is also true for magnetars.)

| Also, not all pulsars appear as pulsars for us, because they rays must hit Earth to be detected.
