And they have detected faint traces in the galaxy’s halo – a vast region of space around the disk. The streams, recorded only in very deep exposures, likely represent the ghostly trail of a dwarf galaxy – debris left behind along the orbit of a smaller satellite galaxy that was gradually torn apart and merged with ngc 5907 more than four billion years ago.
