Expanded local superclusters region size and scale context

This map shows the universe within a radius of 1 billion light-years of Earth, highlighting nearby superclusters and the broader web-like arrangement of galaxies in our surrounding cosmic volume. It represents a much larger neighborhood than the nearer local supercluster maps and includes tens of millions of galaxies. Read its scale context, comparisons, and journey links on the canonical object page.

Between the smallest and the largest, perspective is everything.

About

Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.

Guides turn parts of that scale into curated essays, while focused views let you explore the same range through specific groups of objects.

Large-scale structures

Local superclusters region

This map shows the large-scale cosmic neighborhood within a radius of 500 million light-years around the Milky Way. Instead of a single object, it represents the nearby network of galaxy superclusters, filaments, and voids that make up our local portion of the cosmic web.

Universe

Observable Universe

The observable universe is the part of the cosmos whose light has had time to reach us since cosmic expansion began. Looking deeper into it means looking back in time: Hubble’s deepest fields show galaxies more than 13 billion years in the past, not as they are now but as they were when the universe was young.
