Large Magellanic Cloud size and scale context

The Large Magellanic Cloud is a nearby satellite galaxy laced with vast star-forming regions and supernova debris. It contains the Tarantula Nebula, the most productive stellar nursery in the Local Group, and it hosted SN 1987A, the closest observed supernova since 1604. Read its scale context, comparisons, and journey links on the canonical object page.

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.

Galaxy clusters

Pandora's Cluster

Pandora's Cluster, also known as Abell 2744, is a giant galaxy cluster shaped by a violent and complicated merger of smaller clusters. Its galaxies, superheated gas, and dark matter have been pulled apart and redistributed in different ways, making it one of the clearest natural laboratories for studying how ordinary matter and dark matter behave during colossal cosmic collisions.

Scale fact4 million lydiameter

Object class: Galaxy cluster
Composition: Several hundred galaxies, hot intracluster gas, dark matter

Bullet Cluster

The Bullet Cluster is a pair of colliding galaxy clusters whose components have been torn apart by impact. Its galaxies and most of its mass passed through relatively cleanly, while the hot ordinary gas lagged behind, making the system one of astronomy’s clearest pieces of evidence that most matter in galaxy clusters is dark matter.

Scale fact6.3 million lyobserved field width

Object class: Colliding galaxy clusters
Composition: ~40 galaxies, hot intracluster gas, dark matter
