Which statement describes the formation of the milky way galaxy? a disk formed of long trails of stars coiled into a spiral. it formed an elliptical flattened disk. heat and gases contracted within a nebula. gravity pushed stars away from a center core.

The correct answer is option A which is,"A disk formed of long trails of stars coiled into a spiral".

According to the shape of the milky way galaxies, it has a disk shape in the center of the galaxy and around this disk, there are two spiral-shaped arms coiled around each other.

It contains the stars, dust, and gases and its stars cannot be seen separately.

It is one of the spiral-shaped galaxies. Hence other options describing the elliptical shape are wrong.

Only option A is correct about milky way galaxy.
