During the Universe’s Dark Ages, dense primordial gas absorbed and scattered light, prohibiting it from travelling. Only when the first stars and galaxies began to shine in energetic UV light did the Epoch of Reionization begin. The powerful UV light shone through the Universe and punched holes in the gas, allowing light to travel freely.…

Enlarge / An infrared image of one of the Milky Way's satellite galaxies. We are not alone—at least as a galaxy. About 50 dwarf galaxies surround the Milky Way. But when its intense gravity inevitably draws them to venture too close, they will probably be annihilated. It’s happened before. Though scientists used to think that…
