Hubble Catches a Visible Echo of Light | Hubblecast 71 | ESA Space Science HD HD

Coconut Science Lab: http://www.coconutsciencelab.com Hubblecast 71 explores the striking Hubble observations of a variable star known as RS Puppis. The star grows brighter and dimmer over a period of 5 weeks, as it pulsates. These regular pulsations have created an amazing phenomenon known as a light echo. Please rate and comment, thanks!
