A large, bright feature extending outward from the Sun's surface

The second gaseous layer of the Sun's atmosphere; has a reddish color

The area of the Sun where energy is transported by convection; occurs in the outer layer of the Sun

A layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction, rather than by convection

The cumulative atmosphere of the Sun that is responsible for radiating light

A sudden eruption of radiation from the surface of the Sun

A nuclear reaction in which two lighter nuclei combine to form a single heavier nucleus and some of the original mass is converted to energy

Stable stars in the middle developmental phases that plot along a continuous diagonal belt on the Hertzsprung-Russell diagram

A cloud of interstellar gas and dust created by a dying, low-mass star

A stellar remnant roughly the size of Earth of a star similar in mass to our Sun

An aging, giant star that has consumed its core's supply of hydrogen fuel

The central part of Earth, composed of a solid inner core and a liquid outer core

A nuclear reaction in which a heavy nucleus breaks into two lighter nuclei, releasing energy

A very large star of high luminosity and low surface temperature
