This is called a Nearby Cepheid Variable RS Pup. It is one of the most important stars in the sky due to its large and superlative nebula surrounding it.
Questions:
1. It is described on the NASA website under this photo how it is more luminous than the sun, but how come we do not often see it/why is it not as well known as the sun?
Zoey, perhaps you should look up what is a "cepheid variable" or "nebula" and offer a little more explanation. Why did you choose this photo?
ReplyDeleteSomething could be more luminous, but less visible, if it is further away.
