The nebula in a galaxy is a dead star, long dead, possibly about to turn into a black hole.
actually, its the opposite: nebula is like a cloud of space trash. when the "cloud" gets too big, it explodes. the bigger the explosion, the bigger the new star.
Earth is IN a galaxy - as is the nebula.
A Galaxy is far bigger than a nebula.
A nebula galaxy does not exist.
