A kiloparsec equals 1000 parsecs and a megaparsec represents one million parsecs.
The video tracks an individual system through time, showing its stellar light in a 500 kiloparsec region.
For larger distance, kiloparsec (kpc) or even megaparsec (Mpc) is used.

The artist’s concept also includes a new spiral arm, called the “Far-3 kiloparsec arm,” discovered via a radio-telescope survey of gas in the Milky Way.
The Hubble constant had previously been found to be 72, give or take 8, kilometers per second per kiloparsec based on Hubble Space Telescope observations.

For stars that lie near the plane of the Milky Way and are within a few thousand parsecs of the Earth, extinction in the visual band of frequencies (photometric system) is roughly 1.8 magnitudes per kiloparsec.[4]
It has many more Wolf-Rayet stars per square kiloparsec (5.1 stars/kpc²) than the Large Magellanic Cloud (2.0 stars/kpc²) or the Small Magellanic Cloud (0.9 stars/kpc²).

The source of these exotic electrons must be relatively close to the solar system – no more than a kiloparsec away,” says co-author Jim Adams of the NASA Marshall Space Flight Center.
