How do scientists know about the Milky Way galaxy?
"In the past 75 years, astronomers have refined this picture, using a variety of techniques of radio, optical, infrared and even x-ray astronomy, to fill in the details: the location of spiral arms, clouds of gas and dust, concentrations of moleculesand so on.
Consequently, what is the closest galaxy to ours?
The Andromeda galaxy The Andromeda galaxy, M31, is a faint fuzzy patch that appears, with binoculars, as a lens-shaped object. It is a galaxy rather like ours at a distance of about 2 million light years. It has two dwarf elliptical satellites, which can be seen with a small telescope. Then, which of the following best describe elliptical galaxies? Elliptical galaxies lack the swirling arms of their more well-known siblings, spiral galaxies. Instead, they bear the rounded shape of an ellipse, a stretched-out circle.
Keeping this in consideration, which illustration best represents the shape of the galaxy that includes the sun?

The stars of the Milky Way merge together into a single band of light. But through a telescope, we see the Milky Way for what it truly is: a spiral arm of our galaxy.
