This allows spectra of many stars to be recorded on a single frame, allowing astronomers to compare the elemental composition of stars and other objects. The Pleiades (also Messier 45, NGC 1432) is a naked-eye object in the constellation Taurus, about 400 light years from Earth.

This, together with other innovations, allows a single layer disc to store 25 gigabytes of data. A conventional compact disc stores less than a gigabyte
