Timings: 10 AM to 5:30 PM; Weekly holiday: None; Shows: 10:45 AM (English), 12:00 PM (Tamil), 1:15 PM (English), 2:30 PM (Tamil), 3:45 PM (English)

I was around 9-10 years of age when I first visited this Planetarium – I still remember how I felt immediately after coming out of the show – I was in awe of the whole concept. Those days, as with any other kid, astronomy and space fascinated me. I was pretty sure that I wanted to become an astronaut 🙂 It was such a cool thing to say when someone asks you if you wanted to become an engineer or doctor!

Its near the newly constructed Anna Centenary Library, IIT Madras & Anna University. Like all the other institutions in this place, it is very green and spacious. In fact, one has to walk for around 150 meters to reach the gate from the main road. And all along that road, the side wall has been painted with useful and interesting milestones in Science like the above photo and the below photo.

The Planetarium conducts shows for 5-6 times a day in Tamil and English alternatively, and I went for the English one. This was about the various planets in the Solar System and the last time I came here before about 4 years (For the AC, wanting some respite from the Summer heat), the show was about Moon. I guess they have different topics.

planets projected on dome screen in bm birla planetariumThere is a white coloured dome structure (roof) on which they project the images using a big fancy projector. The seats are almost in lying down position in order to get a clear view of the projected images in the roof. I get thrilled (even now) when they switch off the lights for the first time and the stars come alive over me – Its just like a real night! That makes me wonder – how many years its been since I star-gazed? (In the real sky, I mean).

This one can project at many places on the roof, and you can see the stars almost all over the roof! Should have been tough to make such a thing. It seems, a day in mercury goes on for a whole year! And Venus is named over the Greek God of beauty.

Jupiter is the biggest planet and one of its moon is almost as big as Mercury!  This was first observed by Galileo – In fact he observed four moons in the 17th Century using a Telescope he made for this purpose. Saturn’s beautiful rings are due to the presence of various asteroids in its orbit. Uranus and Neptune are very cold and take many years to orbit around the sun.

Many stars have been observed to have planets orbiting around them, and hopefully one of them will have life! I would be glad if they do find life forms outside our solar system in our lifetime itself. For all they hype they are given in the movies, it would be good to see one real life alien, at least!

BTW, there is a 3D show in another small theater in this Planetarium complex – Its titled as Science show, but all they show is dinosaurs in water and mad scientist creating all kinds of reptiles. The kids were shouting throughout the show. Even I was afraid, and had to apply all my logical reasoning to convince myself that the angry snake with its open mouth coming so near to us is just an illusion! Maybe the whole life is, as well!

    Quite a many informative details… I had been to the Birla Planetorium but didnt go inside the planetorium. The show had already begin and we had to wait for 2 hours for the next show. We spent t time by visiting the science exhibition which is next door to the Planetorium. They had many interesting work models based on various science facts..

      I am doing a separate post on that science museum, that’s why I have not mentioned about it here. I spent almost 4 hours inside the Planetarium complex – They have got quite a few things to keep the visitors engaged! 🙂

    I’ve been always interested in teh Universe and space-related topics 🙂 As a kid, I have many fond memories of visiting the Planetarium and science museum with my grandfather… 🙂 I just went back the memory lane while reading your post…

    • Rajesh K

      I too went back the memory lane while writing this post – I went to the Planetarium as a part of our school excursions. I think these topics are thrilling for all youngsters!

    I remember going to the planetarium when I was little and it left me awestruck. The ambiance they create using the projector is amazing. I makes you forget that you are sitting in a small auditorium. The narration was also very soothing. To be honest it made we want to sleep 🙂

    • Rajesh K

      Yeah, the AC and the Ambiance – I actually went there once for sleeping but couldn’t get doing it because there were so many kids around me shouting! 🙂

      I think they have the planetarium in a number of cities/towns. This is a much needed educational picnic spot in cities.

    I had taken my small children to the Planetarium, many years back, when it was still new. Later on, when my nieces or nephews came, it was a ritual to take them over there and I used to go with them often. It is really great, watching the show.

    You are doing a great job, covering so many things of Chennai, DI.

    • Rajesh K

      Yeah, now I am in Chennai so I can go to various places at leisure – Actually, I could do anything to be away from that laptop screen on weekends 🙂

      It was nice of them to put up that bronze statue of Aryabhatta! He was one of the earliest pioneer from India!

      I think we all loved them when we were young. I just loved it back then when the lights became dark and stars emerged out of nowhere suddenly 🙂
