Ellipse 02

The Ellipse coalesced, probably as a consequence of cooling, and started a new cycle of radiative transfer. This latest formation of the ellipse represents one of the very last big transitions of the Sun's history, the other being the breakup of the previous ellipse in the main sequence. When this ellipse finally ceased to rotate and could no longer continue to pass through the Sun's turbulent outer atmosphere, it became a protostar, a small, dense ball of gas that would eventually become a star.
