In cell biology, the typical star-shaped structure that forms during cell division with distinct poles and radiating microtubules.
From Greek 'eu-' (true, proper) + 'aster' (star); named for the characteristic star-like appearance of the structure during mitosis.
The euaster is like a cellular construction crane—it pulls chromosomes apart with invisible protein cables during cell division, and if this process fails even slightly, you get cancer!
