When I consider thy heavens, the work of thy fingers, the moon and the stars, which thou hast ordained; What is man, that thou art mindful of him? and the son of man, that thou visitest him?
Psalm 8:3,4
There must be a purpose for this intricate
interplay in the Creator's skies....the interwoven fabric of the cosmos...is this some sort of cosmic battery? Some sort of cleaner?...hmmm....
"The millisecond pulsar PSR J1023+0038 is known to switch between
two brightness modes almost constantly, something that 
until now has
been an enigma.
Over the past decade, PSR J1023+0038 has been actively pulling matter
off this companion, which accumulates in an accretion disk around the
pulsar and slowly falls towards it.
Since this process of accumulating matter began, the sweeping beam
virtually vanished and the pulsar started incessantly switching between
two modes.
--In the ‘high’ mode, the pulsar gives off bright X-rays, ultraviolet
and visible light,
--while in the ‘low’ mode it’s dimmer at these
frequencies and emits more radio waves.
The pulsar can stay in each mode for several seconds or minutes, and 
then switch to the other mode in just a few seconds. This switching has
thus far puzzled astronomers.
“We have discovered that the mode switching stems from an intricate
interplay between the pulsar wind, a flow of high-energy particles
blowing away from the pulsar, and matter flowing towards the pulsar,”
said Dr. Francesco Coti Zelati.
In the low mode, matter flowing towards the pulsar is expelled in a narrow jet perpendicular to the disk.
Gradually, this matter accumulates closer and closer to the pulsar
and, as this happens, it is hit by the wind blowing from the pulsating
star, causing the matter to heat up.
The system is now in a high mode, glowing brightly in the X-ray, ultraviolet and visible light.
Eventually, blobs of this hot matter are removed by the pulsar via the jet.
With less hot matter in the disk,
the system glows less brightly,
switching back into the low mode."
