NASA. LARGE FORMAT. HUBBLE TELESCOPE. This Hubble image shows RS Puppis, a type of variable star known as a variable Cepheid. Cepheids have relatively long periods - RS Puppis, for example, varies in brightness by a factor of five every 40 days or so. RS Puppis is unusual: this variable star is enveloped by thick clouds of dust, which allows us to observe a phenomenon known as luminous echo with astonishing clarity. These Hubble observations show the ethereal object embedded in its dusty environment, against a background of dark skies filled with galaxies. 2010.period chromogenic print. Numbering in the margin on the front. Legend on label on the back. 40.6 X 40.6CM with margins.
