Hubblecast 71: Visible echoes around RS Puppis

December 17th, 2013

Episode 19 of 47 episodes

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.
