A galaxy contains stars, gas and dust. In a spiral galaxy like the Milky Way, the stars, gas, and dust are organized into a "bulge," a "disk" containing "spiral arms," and a "halo." Elliptical galaxies have a bulge-like central region and a halo, but do not have a disk.

Galaxy
Most of the observation astronomers make are inside our Galaxy. Of course we still find new things. The Milky Way is a very complex and diverse collection of celestial objects. We still have much to learn!
All depending on what "It" is could alter the answer greatly I suppose. You can find contrast easly in any two objects, but to find what is different i would find the likenesses first and go on from there :)
The scientific name for outer space is galaxy. The galaxy that Earth is in is called the Milky Way Galaxy. Scientists may also refer to outer space as the Universe.
H II regions are regions of ionized gas in a galaxy that emit strong emission lines, allowing astronomers to determine the galaxy's distance using spectroscopy. Cepheid variables are pulsating stars with a period-luminosity relationship that allows astronomers to determine distances to galaxies based on their observed brightness variations. While both methods are used to measure extragalactic distances, they rely on different physical properties of objects within the galaxy.
