For sure - galactic clusters. Expansion of the universe is demonstrated via the redshift of galactic clusters (outside of the local galactic cluster which hosts the Milky Way galaxy). Pulsars may also provide some insight into expansion via the emission of their light signatures, but it is not generally considered a specific support (in and of itself).
The existence of galactic clusters is consistent with the Big Bang although it would be equally consistent with the alternative Steady State theory.

the 3 clusters of PECs are Achievement Clusters , Planning Clusters and Power Clusters
Clyde Tombaugh was the astronomer who discovered Pluto in 1930, while working at Lowell Observatory in Arizona. Tombaugh also found a comet, hundreds of asteroids, and several galactic star clusters.
They form galaxies, galactic clusters, and galactic superclusters.

Galactic clusters radii range from 1 to 5 Megaparsecs. A megaparsec is about 3.3 million light years.

what is the thin gas and clusters of stars surrounds the disk of the Milky Way Galaxy.
The Galactic halo is the spherical region surrounding the disk of a spiral galaxy which contains globular clusters and reddish population II stars.
"The halo primarily contains individual old stars and clusters of old stars ("globular clusters"). It may be over 130,000 light years across. The halo also contains "dark matter," which is material that we cannot see but whose gravitational force can be measured." to shorten the answer - individual stars, clusters, and dark matter.
Clouds of cool hydrogen.
