The biggest blobs

This is a huge blob of gas & stars forming a “galaxy” maybe 200 million lightyears wide.

The official word is “The structure we discovered and others like [it] are probably the precursors of the largest structures we see today which contain multiple clusters of galaxies” This one’s several times the size of Andromeda galaxy & was observed using Hawaii’s Subaru & Keck ’scopes.

Theories as to the blobs’ origins & nature vary, typically picturing them as either blowouts from massive early stars supernovaing to “gas cocoons” harbouring new galaxies-to-be. It’ll probably become an interesting debate to follow.
