We can only see about 4 percent of our universe. The rest is mysterious, invisible dark energy and dark matter, which scientists still dont know very much about. Obviously, theyd like to learn more about the other 96% of the universe. But how do you study something you cant see? Well, one option is to study the dark parts of our universe indirectly, by looking for ways they might be influencing the visible universe. And earlier this year, an international group of astronomers confirmed that some of those clues pointed to a small, undiscovered galaxy, mostly made of dark matter, orbiting our own galaxy. Its being called Galaxy X. Back in the 1970s, astronomers were measuring the rotational speeds of galaxies, and they noticed something surprising: the objects as the edges of galaxies had velocities that didnt fit with the astronomers calculations. The researchers were predicting the movement of objects in the galaxy based on the amount of visible matter, and its gravitational infl
