From Milky Way To Andromeda, Another Question Of Scale.


Recommended Posts

Posted

This galaxy,

 

Andromeda

 

is said to be similar in size to our own.

 

As I look up at the night sky, am I looking up towards the top of a spiral arm of the Mily Way, or towards the centre of our galaxy?

 

When I look at the several thousand stars in the sky above me, approximately how many square millimetres of that photo at that link above, would represent the portion of the night sky that I see?

 

Or would it just be a pixel or so of that photo?

i think it's quite natural for people to want to visualise where they are in the universe....is my question beyond even the great minds in this forum? :-)
