I came across a similar object while writing up a talk on planetary nebulae a few days ago. Apparently a star knowns as Vela -X1 is moving at high speed and seems to be ejected from the Gum nebula. APOD describe it as a "Runaway Star". Funnily enough it is also a Pulsar.

i just hope it won't on a crash course to our sun,will it?

Stars are routinely ejected from our galaxy (and all other galaxies) due to gravitational slingshot effects.

The more times a star orbits its host galaxy, the more erratic its orbit becomes, and some stars end up being ejected.

Facinating.
