I would have liked this to be a bit more in-depth. Like, what temperatures did you actually end up with based on the RGB values from your camera? Also, changing the white balance in the camera could affect your measurement. How do you counteract that?

But there is something else that you need to put in your calculation. If a star is moving towards earth it shifts the star's spectral lines towards blue. If it is moving away from us it shifts towards red.

I have an insane question: We know that the Earth spins around itself and orbits the Sun. So if somehow, we can reverse the way the Earth spins around itself and orbits the Sun then will TIME go back (in the past instead of future). So, basically, can we control time like creating a time machine?

Shadman Al Hossain I see you got a amazing question right there... But, that's not possible.Example : Take yourself walking to your school and returning back to home does this reverse the time for you?.Same way the time is not reversed if you go in just the opposite direction ( *same goes for earth* ). Easiest way to travel time could be staying at the epic centre of a black hole or stay on a planet with longer hours(INTERSTELLAR STUFF)

The temperature of a star must decrease when its light travel a distance. So what we see are not their actual temperatures and also.. their distances are not same either.. So you can simply say a star is at this temp now as we dont know the distance.

The Sun is actually white. If it was yellow, white paper would look yellow (shine a yellow light on paper to see). The reason we think of it as yellow is because we normally only look at it during sunset/rise, when the atmosphere causes it to become more yellow.
