The Spookiest Sound in Astronomy
Ah, the sounds of late summer. Pass a pool, and hear the happy yelps of kids splashing around. Sit outside at night, and bask in the soothing buzz of cicadas hidden in the trees. Open the internet, and hear the terrifying howling of outer space.Thank NASA for that last one. The space agency recently shared a clip online of sound coming from a cluster of galaxies about 250 million light-years from Earth.
