Mysterious Pulsar 'Vanishes' into Spacetime Warp; will 'Re-apprear' in 2170

(Photo : Wikipedia) Pulsars can create a spacetime warp via gravitational waves.
Scientists have detected a pulsar in the farthest reaches of the universe that mysteriously disappeared because a spacetime warp tilted its beams away from Earth.
The heavy pulsar orbits a neutron star or a white dwarf in close proximity. The gravitational forces emitted by these galactic objects are so massive they're emitting waves across the galaxy that bend spacetime, causing the pulsar to wobble in its orbit.

Astronomers have been tracking this motion for almost five years and have determined the weight of the pulsar and the amount of gravitational disturbance it creates.
In a surprising turn of events, the pulsar suddenly vanished into oblivion. Researchers classified this event as a "precession" or a change in the orientation of the rotational axis of a rotating body such as a star.
Precession occurs when a dying star falls into a wobbly orbit and dives into spacetime originating from its own orbit.
This particular pulsar is also classified as a dense neutron star or a collapsed fragment of a supernova. According to study lead author Joeri van Leeuwen of the Netherlands Institute for Radio Astronomy, these pulsars possess more mass than the Sun but only measures 10 miles across.
These neutron stars or pulsars generate spacetime ripples called gravitational waves, especially when they come in binary systems.
This particular pulsar called the Pulsar J1906 showed-up unexpectedly during a survey by Van Leeuwen at the Arecibo Observatory in Puerto Rico. These two pulsars orbit each other in just four hours, which is the second fastest orbit ever seen.
A pulsar spins several times every second while emitting radio waves in the direction of our planet.
Scientists have recorded one billion rotations from the pulsar. Each pulsar is 1.3 times heavier than our Sun.
