Visible Light Echoes around Variable Star RS Puppis Explained | Hubble

Visible Light Echoes around Variable Star RS Puppis Explained | Hubble

Hubblecast 71: 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.

Distance: 6,500 light years
