The holy month of Ramadan is approaching, and the annual controversy about the observation of Ramadan crescent and the beginning of the lunar months has begun. The same questions rise again:

- Can the astronomical calculations substitute the visual observation?
- Which is more accurate?
- What is the Lunar calendar?
- How we observe the crescent?
- What are the moon phases?

In May astronomy night, we will answer all these questions and more…
The night also includes telescope observation for the moon and its craters, and Jupiter with its marvelous rings while it is extremely near to Earth this year.
