Galactic 'Eyelids' Show Space Gas 'Tsunami' (Photo)

Look out! A "tsunami" of gas is crashing through a spiral galaxy, creating an image that bears a striking resemblance to a pair of eyelids. The turbulent zone formed when a galaxy called IC 2163 brushed by another one, named NGC 2207. The collision zone, located some 114 million light-years from Earth, was inspected for a new study with the Atacama Large Millimeter/submillimeter Array (ALMA), a large radio observatory in Chile.
