Variable star Quiz

The brightness of a star can change with time. When observing from earth, the flickering of stars is due to minor turbulence in the earth's atmosphere. But when measured more accurately, many stars show a degree of variability in their brightness. There are many different types of variable stars.
The two main types of variable stars are,
                                          1. Intrinsic variable stars
                                          2. Extrinsic variable stars.
Intrinsic variable stars change their brightness due to changes in the properties of that star, while the mechanism of an extrinsic variable star involves an object outside the star.

If you are confident about your knowledge in variable stars, try this Variable star Quiz.

Organizing a Quiz 1: Finding a Name

While there are many astronomy quizzes, only few will stand out. One simple difference lies in the name itself. When you have a lot of  generic 'astronomy quizzes' it's difficult to identify your one against the many others.
When I was involved in designing the astronomy quiz in Anandian Astronomical Association, we wanted to differ from others. There were quite a few astronomy quizzes but we got permission to get the Sir Arthur C Clarke's name, simply because we thought differently. Many would have thought it might get rejected, but no one has tried.

But a general understanding of astronomy can narrow down your options, which itself can lead you to the answer. Familiarize yourself with different space missions in different times of the year. Some are more significant than the others. Some missions failed which some made breakthroughs in science.
