It's a [huge:high] collection of stars and other matter that shaped like a spiral or no lips and if you're an astronomy fan you probably know that most the [masses:meaning] from invisible mysterious material called dark matter. Well, NASA's Hubble Space Telescope just took an [image:picture] of a galaxy that is none of those things. For the [first:last] time astronomers have strong evidence for a galaxy not having a significant amount of dark matter. Most astronomers currently [believe:trust] that dark matter plays a fundamental role in our universe and the [formation:fonts] of galaxies. This is because galaxy seem to have a lot more mass than what we can account for based on just the stars we see. How much masses in the system is determined by measuring the [speed:route] at which galaxies rotate or individual stars in a galaxy move.
