This misalignment indicates that they were formed in a pair of fragmented gas clouds produced through turbulence, not via evolution of tightly - coupled twin.

Because the Universe originally lacked metals (elements heavier than lithium) that cool collapsing gas clouds today, the earliest stars were more massive and burned much hotter than even the largest stars we study today.

Its spiral arms squeeze interstellar gas and dust, causing gas clouds to grow dense, collapse and create new stars; the brightest newborn stars illuminate the arms so gloriously that spiral galaxies resemble glowing cosmic hurricanes.

Because the primordial gas clouds stayed warm, more gravity was needed to overwhelm the gas pressure and make them collapse, so they spawned massive stars.
