The world’s largest planetarium will welcome you!Let’s experience the wonder of science with five senses.
Shirakawa Park near the downtown area of Nagoya City (also known as the Forest of Art & Science). In the Park, there is Nagoya City Science Museum looking like something to appear in SF movies. It consists of three buildings; Astronomy building, Science and Technology building, and Life Sciences building. Especially, a spherical structure of the Astronomy building attracts attention. In the upper half of this sphere, the world’s largest planetarium dome “Brother Earth” is located. Now, in addition to the planetarium, we will introduce four popular large exhibits; “Exploring Water”, “Tornado Lab”, “Electric Discharge Lab”, and “Deep Freezing Lab.” By understanding science and technology deeply involved in our lives through these facilities, you must be able to find something interesting and fun just a little bit different from amusement parks.
In the Guinness Book-registered planetarium [Brother Earth], a sense of different dimension is also Guinness class!?
Aiming to replicate an actual starry sky as accurately as possible, the renewed planetarium [Brother Earth] was open in March 2011. With a 35-meter inside diameter of the dome, it has been recognized in the Guinness Book of World Records for the world's largest planetarium. Equipment to reproduce the starry sky installed in the dome is also the world’s most advanced system. As a core of the system, two projectors are used. The optical “UNIVERSARIUM Model IX planetarium” (upper photo) can replicate locations of visible 9,100 fixed stars, project celestial scenes uncanny in their realism, and make the stars twinkle to the life. The digital “Sky Max DSII” has memorized moves of 100,000 fixed stars. It can even project the starry sky in the past and future, and enable visitors to experience simulated space travel.
However, looking up at the night sky for a long time, your neck would hurt. Here, you don’t have to worry. Spacious large reclining seats are available. The entire seat can also swing right and left. It’s so excellent. With exclusively designed sound systems, you can comfortably enjoy seeing the starry sky.
Projection time is approx. 50 minutes. The Projection that tourists can enjoy is called “General Projection”. Please note that the schedule of General Projection varies depending on days.
[Exploring Water] full of unique experiment equipment
“Exploring Water” is kids’ favorite large exhibit using the double-height space on the 2nd and 3rd floors of the Science and Technology building. It consists of four stages for clouds, rainfall, rivers, and oceans. The process of water circulation and the properties of water are shown with dramatic lighting and sound. Starting every 5 minutes before every hour, it is performed for approx. 5 minutes.
Moreover, in each stage, equipment is exhibited, which enables visitors to deepen their knowledge through experiments, for example, “water prism” to show the process that water becomes prism, “shape of raindrop” to show the shape of raindrop at time of falling down through the air, “flow and whirlpool” to show the shape of whirlpool’s changing depending on shapes of objects, and “solid soap bubble film” for learning about surface tension.
You can experience a real tornado!? [Tornado Lab]
On the 3rd floor of the Science and Technology building, there is equipment to generate a 9 meter-high huge twister (you can observe from the 4th floor). In this experiment using a vortex of wind and ascending air current, staff explains about the mechanism of tornado.
In order to generate a tornado, a rotating flow generated by cold air and warm air striking each other and strong ascending air current are required. The rotating flow is made with wind blowing in the horizontal direction from three pillars, and the air is sucked up from above in order to generate the ascending air current. The show is performed three times on weekdays, and four times on Saturdays, Sundays, and Holidays. The required time is approx. 15 minutes.
Incidentally, a size of tornado is expressed with a F scale from F0 to F5. The largest tornado that has been observed in Japan is F4. Although the artificial tornado has an elongated shape, the actual natural tornado has a conical shape that becomes thicker as ascending higher.
In [Electric Discharge Lab] you will be surprised at electric sparks and roaring sound.
On the 4th floor of the Science and Technology building, you can see an fully impressive electric discharge show. From two big towers, electric sparks are emitted with roar. Bluish-purple bolts four meters long extending in the air look like a living thing.
These large towers are equipment called Tesla coils, which can generate high frequency and high voltage. Voltage varies depending on a turn ratio of the coil. Things using this principle include AC adopters of personal computer and transformers of power poles immediately around us.
The required time for show is approx. 20 minute. It is performed 5 times a day on weekdays, and 7 times a day on Saturdays, Sundays, and Holidays, as well as during holiday periods in spring, summer, and winter. As the capacity is 60 people per show, a numbered ticket is required. The numbered tickets are delivered at the north aisle of Science State on the 4th floor.
Experience the world at -30 degrees in [Deep Freezing Lab]!
Few people have experienced temperature of minus 30 degrees centigrade. On the 5th floor of the Science and Technology building, you can do it. In that space, the eyelashes would be frosted, and the exposed skin would feel pain rather than cold. In the Deep Freezing Lab, you will enter the room at minus 30 degrees centigrade after training the body for about two minutes in the room kept at minus 10 degrees centigrade (and vice versa when leaving the room).
In the room at minus 30 degrees centigrade, the image of aurora is flickering on the ceiling and ice of the Antarctic Pole is exhibited. Therefore, you will enjoy the atmosphere as if you were in the polar region.
The experience time is approx. 20 minute. It is performed 11 times a day on weekdays, and 12 times a day on Saturdays, Sundays, and Holidays. As the capacity is 20 people per show, a numbered ticket is required. The numbered tickets are delivered beside the entrance of Cold Protection Lab. As warm clothing is lent, you do not have to bring anything.
