If space weren't scary enough already, here's another reason to be spooked: galaxy clusters that look like flaming skulls. The Perseus Cluster lies about 300 million light years away and stretches over 100,000 light years across.
The brighter areas represent more intense areas of x-ray radiation (white is the most intense while red is less intense).
