![]() This means that their true brightness can be calculated and compared to the brightness of them as seen here from Earth-doing so allows for very accurately measuring how far away from us they are. They were useful to the researchers because they pulse with regularity and brightness. ![]() More specifically, the researchers wanted data regarding Cepheids, which are a unique type of pulsating star. To create their new map, the researchers used data from the Optical Gravitational Lensing Experiment-a long term sky surveying project based at the University of Warsaw. In this new effort, the researchers have found that our galaxy is even more wobbly than has been suspected. ![]() In more recent times, however, scientists have discovered that our galaxy is not flat at all-it is more like a wobbly uncooked pizza crust that has been tossed into the air. Most people imagine the Milky Way as a flat spiral-that is the way it has been shown in school textbooks for years.
