When determining a star's surface temperature, what do we need to know? - The peak wavelength 
of its blackbody spectrum 
The star Betelgeuse has a lower surface temperature than the Sun; therefore (with IR = infrared 
and UV = ultraviolet) - Betelgeuse emits more IR and more UV light than the Sun....

Why do we see the Moon appear to go through phases as seen from Earth? 
A. The Moon reflects "Earthshine", so it depends on how much light from the Earth is hitting the Moon 
B. As the Moon rotates, it presents a different phase to us over the course of its "day". 
C. Depending on where the Moon...
