Cosmic ‘Eel’ Preys On Spiral Galaxy

A giant space “eel” appears to be chasing after a spiral galaxy in this newly released image from the Victor M. Blanco telescope in Chile.  The eel is actually a type of small, isolated cloud of gas and dust, called a cometary globule because of its resemblance to a comet. Called CG4, it lies about 1300 light years from Earth towards the constellation Puppis, at the stern of the ship of the Argonauts (a former constellation called Argo Navis).  CG4 is a star-forming region within the Milky Way with enough material to produce several stars the size of the Sun. Its head is about 1.5 light years wide and has been sculpted into the shape of an open mouth by radiation from hot, nearby stars, whose scattered light also causes the CG4 to glow.
