Welcome to StarNews! In today's episode, we explore the intricacies of cosmic structures. We start with understanding the superclusters - enormous cosmic structures defined not by their boundaries but by the common motion of their constituents. 

First up, we debunk the long-held belief that the Milky Way is part of the Virgo Supercluster. New insights reveal that while the Virgo Supercluster is substantial, it's only a branch of an even grander structure called Laniakea, home to about 100,000 galaxies.

We delve into how early galaxy surveys led astronomers to discover clusters and ponder the existence of higher-order structures. Today's astronomical technology provides deep universe mapping, revealing the cosmic web and the vast voids that shape it.

We cap off with a discussion on dynamic definitions of superclusters, stressing the significance of not just the positions but also the movements of galaxies within these colossal formations. Tune in to unravel the universe's most immense structures with StarNews!
