It’s hard for most of us to fathom that every star we see in the nighttime sky is another sun similar to our own. Scientists are discovering that around many of those stars are orbiting planets creating vast numbers of solar systems. There are other objects in the nighttime sky that we can’t see, including dark matter.
Dark matter is invisible and accounts for about 80 percent of the total matter in the universe. Scientists have been working hard for decades to learn as much as possible about dark matter and the role it plays in the universe as we know it. Scientists have now created the largest map of dark matter ever as part of the international Dark Energy Survey.
