A
this would be the emission and absorption lines in the light spectrum. certain elements absorb or emit wave lengths of light that is unique to that element. by studying the "rainbow" of the star astronomers can determine its properties and elements by looking at which wave lengths of light are absorbed or emitted.
A blueshift in the galaxy's spectrum - that is, the frequency of the light, as observed by us, is greater than when it was emitted.
No. That would violate the laws of physics.

the earth would melt
Physics would probably be the most obvious choice.

G40 is a supernova remnant. Particle physics is the study particles, radiation and matter. One would be able to study the properties of the G40 by applying the principles of particle physics
