It's the CENTRIOLES and their star-like radiating structures, called asters.
This is Stage 1 in Mitosis:
Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to the opposite sides of the nucleus. Spindle fibers form a bridge between the ends of the cell. The nuclear envelope breaks down.
The two pair of centrioles move towards opposite ends of the cell during prophase. A mitotic spindle of fibers is also formed.

Telophase is essentially prophase in reverse.
Chromosomes
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.
The cellular event that happens by removing the nuclear envelope is cell division. Cell division happens during Prophase.
The chromatin condenses into thick thread-like structures that later become chromatids.
Cellular Division.
The centrioles move toward opposite poles during prophase. During prophase the nuclear membrane disintegrates. Spindle fibers appear during the prophase.
Telophase is essentially prophase in reverse.
The centrosomes, which contain the centrioles in animal cells, not plant cells.
Chromosomes
During prophase, the nuclear membrane and the nucleolus dissolve and disappear.
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.
