Energy moves through the Sun's convection zone by means of the rising of hot gas and falling of cooler gas.

Nearly all the visible light we see from the Sun is emitted from the photosphere.

Most of the Sun's ultraviolet light is emitted from the narrow layer called the chromosphere where temperature increases with altitude.

We can see the Sun's corona most easily during total solar eclipses.

The radiation zone is the layer of the Sun between its core and convection zone.

Which of the following layers of the Sun can be seen with some type of telescope? Consider all forms of light, but do not consider neutrinos or other particles.

Stellar nurseries, such as the Orion nebula, contain hundreds or more fragmenting and contracting regions, as well as many protostars and stars. What condition would allow a protostar to become a stable star?

Compared with Earth's diameter, the Sun's diameter is about

Overall, the Sun's average density is roughly the same as that of

If astronomers lived on Venus instead of on Earth, the solar constant they measure would be

According to the standard model of the Sun (Figure16.6 in the textbook), as the distance from the center increases, the density decreases

A typical solar granule is about the size of

As we move to greater and greater distances above the solar photosphere, the temperature in the Sun's atmosphere

The time between successive sunspot maxima is about a

The primary source of the Sun's energy is

Why does fusion only occur under conditions of extremely high temperature?

Which of the following is a particle produced in the proton-proton fusion reaction?

The solar neutrino problem is that
