There was a competition on designing a t-shirt for Astronomy Club. Kang Zhe designed this and won the competition, thus this shirt is now the Astronomy Club shirt. The front is plain and simple with the SST logo while the back has white dots as stars, and they form a constellation that resembles the SST logo. The motto "See the BIG picture" encourages everyone to not only focus on the small things in life, but to take a step back and look at everything.

The teachers bought us lunch sets and we waited for a while for the seniors to complete their exams. We all ate food together as it was the Sec 4s' last astro session and we wanted to bid them farewell. They have guided me a lot, from my first astro trip to operating a telescope.

I chose this photo because it says that events like these bring people together, whether be it about the Sun, the planets or just the stars. As quoted in Interstellar, “Love is the one thing that transcends time and space.”, and I think this photo proves it.
To many people, the Sun is a light source. It separates day and night, indicates sunrises and sunsets. However, the Sun is more important than we think. Not only does it give us light, it is why we are alive today. Earth is comfortably situated in what astronomers call the “Goldilocks Zone”. It is an imaginary region where life is able to form, where it is perfect for life. We are the only known planet that can sustain life, and that in itself is amazing. The light rays from the Sun, due to their wavelength and frequency, are absorbed by plants and converted into chemical energy through the process of photosynthesis. This is how plants make food. Animals come along and eat the plants as food, which helps them grow. This is how all of life is sustained by the Sun.
Imagine if the Sun disappeared for just 30 seconds. Due to the absence of its gravity that holds the Solar System together, all of the planets would spiral out of control and collide. Moreover, they would all freeze over. On Earth, everyone would freeze to death due to the lack of heat. The plants do not receive sunlight or heat, and they would freeze. All of life would not survive.
In conclusion, the Sun is vital to all life on Earth. It is the one thing that holds everyone here from death, and the one thing that indirectly provides us with air we breathe and the food we eat.

This is the image of the Sun through a solar telescope. The image is blur, showing that even though we do have materials to look at the Sun and study it, we still do not know everything about it and its secrets, and have a lot more to learn.
