Cepheid Variable in NGC 3370 - NASA Science
Here we see a "movie" of 12 consecutive epochs of a long period (~50 days) Cepheid variable. The Cepheid is in the center of a crowded region of stars. The resolution of HST is required to pick out the variable star from its neighbors. The star was caught initially fading before...

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
