There are few astronomical concepts one can learn by mere observation of the sky. We learnt gravity at school as a force that binds everything together in this universe. Much the same way the planets are attached to Sun, the stars are attached to their respective black holes because of gravity. Moon has a noticeable gravitational pull on Earth and that is reflected in the tidal movements. We can easily understand the correlation between the tidal movements and Moon’s position by visiting a beach.
Earth’s seasons are influenced by the Sun’s position in the sky. Summer happens when the Sun is overhead and the winter happens for Northern Hemisphere when the Sun stays low on the southern skies. This can be confirmed by mere observation of the night sky.
Given below are the concepts one can understand by mere observation of night sky.
1. Moon is lit by the Sun
2. Moon causes the tides in our oceans
3. Sun’s position in the sky causes the seasons on Earth.
4. Venus is an inferior planet to Earth (closer to Sun than Earth is)
5. Differentiating planets from stars.
You seem to have studied a lot on astronomy. Is this your hobby?
Thanks for sharing this! Astronomy is really an interesting topic. I don’t know much about astronomy, but I would like to learn more. My eldest son is interested in astronomy, or kids just like it, so I’ll have to study more and then tell my kids about it.
I love watching the moon and the stars, but then I have no clue about the constellations. 😀
Nice astronomy,it’s nice to be seen in my life if able to make it.
Nice statements! I like night observations
I would say that #3 is more indicative of the axial tilt, but you could argue that it is the same thing
I have a telescope on my back porch. Lots of light pollution, but early in the AM (330 or so) you can see the universe!
Yes DocAndersen. Light pollution affects not just the stargazers but also the birds that depends on position of stars to navigate.
It truly does, great share – thanks!
Very interesting information. I learned a lot of new things.
Thanks Vidocka for your nice comments.
Thanks for this information. I love watching a night sky.
Thanks Carol. Night sky offers plenty of visual treats. I am glad you enjoy watching the night sky.
Yes it does indeed. Enjoyed a harvest moon the other night. Gorgeous.
Yes Carol. Moon offers plenty of visual delights, being the brightest and closest object in the night sky.
