What structure is formed by the large envelope of gas and dust ejected by a dying, low-mass star?
Answer
A planetary nebula
The vast shell of gas and dust expelled by a star like the Sun during its final transition phase expands and cools, creating the visually observable structure known as a planetary nebula.
