Wow...“Above and below the galactic plane, two huge plumes of gas extend 700 light-years.”
For reference, the diameter of the solar system to the far edge of the Oort Cloud is about 1 light-year. The Oort Cloud is 100,000 times father from the sun than the earth. The average orbital distance of Pluto is 0.0006 light-years from the sun.
This is probably what our galaxy looks like from another galaxy.....................
