Cepheid Variable Star RS Puppis 24/03/2018 • The super star is ten times more massive than our Sun and 200 times larger. • Its average intrinsic brightness is 15,000 times greater than our Sun's luminosity. • Distance to RS Puppis has been narrowed down to 6,500 light-years (with a margin of error of only one percent). This movie shows the reflection nebula around the Cepheid variable RS Puppis at seven equally spaced intervals during its 41.4-day pulsation period. Each time RS Puppis reaches ma

SOLVED:Go to the Goddard Multimedia website and view the animation of a Cepheid variable star in a spiral galaxy (http://svs .gsfc.nasa.gov/goto?10145). Explain how astronomers use data like these to estimate the distance to the galaxy. What is actually observed, what is assumed, and what is calculated? (Review the discussion in Chapter 16 as needed.)

Cepheid Variable Star RS Puppis | Hubble’s Inside The Image | NASA Goddard FriendsofNASA.org: The Hubble Space Telescope has taken over 1.5 million observations over the years. One of them is the incredible image of RS Puppis. RS Puppis is a remarkable and highly luminous Cepheid variable star located in the constellation Puppis, known for its regular pulsations and dramatic changes in brightness. In this video, Dr. Padi Boyd explains this breathtaking image and how important Hubble is to explor
