Question

In the dying stages of our Sun, after it has become a red giant, it will shed much of its atmosphere as:

a. A smaller nova explosion

b. A cold molecular cloud (Bok Globule)

c. A massive supernova explosion

d. A planetary nebula

Answer 1

After becoming a red giant, the Sun will shed its atmosphere and form a planetary nebula as its core collapses.

Step-by-step explanation:

After the Sun becomes a red giant, it will shed much of its atmosphere and form a planetary nebula. This is the result of the star losing mass as its core begins to collapse. The mass loss exposes the hot inner core, which appears at the center of the planetary nebula. Planetary nebulae are shells of gas ejected by dying stars and are set aglow by the ultraviolet radiation of the central star.
