Full Map of the Milky Way


I stumbled upon this a couple of months ago, and it really helped me understand the scale of the Milky Way. On the top right you can see what percentage of the galaxy your view is taking up. The amount of stars in the galaxy is inconceivable. And to think that there is an entire galaxy for every star in the Milky Way, probably even more than one.

And then one remembers that Earth itself is a very small rock orbiting just one star. It amazes me that we use microscopes to study the same physics that also governs things on that scale. As in, you have to use a microscope to know enough to understand your observations of the Milky Way.

Looking at things like this make me excited for the James Webb telescope, which will hopefully give us more accurate assessments of the galaxy and universe.
