Hubblecast 71: Visible echoes around RS Puppis

The ESA astronomy podcast, bringing you the latest from the Hubble Space Telescope

17 December 2013

This episode of the Hubblecast explores striking new Hubble observations of a variable star known as RS Puppis. This star is growing brighter and dimmer as it pulsates over a period of five weeks. These pulsations have created a stunning example of a phenomenon known as a light echo, where light appears to reverberate through the foggy environment around the star.
