Seeing Double: Spitzer Captures Our Galaxy's Twin
What would our Milky Way galaxy look like if we could travel outside it and snap a picture?
Comments:
If we can't get far enough outside the Milky Way to take picture of what it actually looks like, how on earth can we realistically say that a picture of another galaxy is what ours looks like? :S
Because many astronomers have spent countless hours studying and mapping the structure of our Milky Way. See:<br><br>http://www.anzwers.org/free/universe/milkyway.html<br><br>as a starting point. We have a good general idea about how our home galaxy would appear to an external observer.<br><br>---<br>Michael McCulloch
