Hubblecast 71: Visible echoes around RS Puppis
Channel: HubbleWebbESA
Date: 2013-12-17

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.
