I like that I can talk to my friend from another class. I also want to meet some people with similar interests.
I could have talked a little softer and spoken to more people than just those I know. I could have asked more questions regarding what happens during CCA and paid more attention.
No

I learned about solar and lunar eclipses today, along with how the orbit and tilt of the earth's axis affect the changes in seasons. I like to try out the software and look for stars and other objects in the sky. I felt like I was engaged during the lesson and actually managed to learn a few more things, such as what a Magnastar is. I also want to try the simulations.

I heard my CCA mates present about what they learnt in the past lesson. I also reflected and remembered what I learnt in the past session and understood further how the astronomical coordinates work. Making the slides was fun, and I got to work with others, even if they were not very cooperative with each other. My classmates, however, were not very attentive listening to others' presentations. 👍🏻

I learnt about gravity, orbits and the 3 Kepler laws. I also learned what would happen if the universe stopped expanding/changing. I think scientists use light years to measure distance instead of kilometres as it is not easy to measure how far something that is not tangible is exactly, but you can measure how long it takes for light to reach us. Also, the space is very big, so the number would be very, very long if they were to use kilometres. 🫡

If I could travel back in time, I would convince my leaders to use astronomy by first predicting certain events and proving that I was correct. I'll also ask them just to trust me. Depending on the colour of the light from the stars, you can tell if the stars are moving away or towards you. 💁

I learnt about the different parts of a telescope, who invented them, and how to assemble and disassemble them. I learnt that 1. telescopes are very heavy. 2. Telescopes can see very far, but if you use them to see nearby objects, the image becomes blurry. 3. Telescopes basically reflect light with lenses to see distant objects.

I learnt about different habitable planets in the galaxy, and that a small change in factors like the atmospheric pressure of the planet can cause it to go from habitable to not habitable. I think that Newton has a greater influence in Astronomy as he was the one who discovered gravity, and Galileo's works just added onto what he already did. In addition, Newton's discovery of gravity likely led to a change in the mindset of astronomers about how objects in space functioned, including laying the foundation for Kepler's laws. In conclusion, Newton had a greater influence on Astronomy as this discovery laid the groundwork for multiple other discoveries that also greatly influenced Astronomy.

I built a 'moon base' called autism central and learnt a little bit more about the moon. I think I could have added some heaters, more water, and more research equipment in the moon base, as I made it more of a 5-seasons hotel than a base used for research. And learnt about the factors needed to determine if liquid water can exist on a planet. (Atmosphere of the planet, luminosity of the parent star, type of parent star, and the planet's albedo.)

A spacebase will be built on Mercury using simple things like what we do with a moonbase; however, we can make the walls thinner as Mercury still has an atmosphere and has oxygen. However, like on the moon, we must bring water, soil and other things needed for survival. However, the walls and the materials would have to be poor conductors of heat, as you would be cooked if you lived on mercury without any protection from the heat.

I played a booklet quiz and heard about projects my seniors did for the Thai conference. They had a project on measuring the speed of the Milky Way using the Doppler shift. I also learnt how to play KSP. I liked today's session as we mostly just played games without learning anything, so it was more relaxing compared to regular sessions.

I learnt about Thermal energy, the anatomy of a star, like the corona, chromosphere, photosphere, nuclear fusion and fission. I think the anatomy of a neutron star would be similar to a regular star, just with a crust and atmosphere. I think a red and white dwarf star doesn't have much anatomy other than the core since it has already shed its outer layers.

I like today's session the most as we got to roam around the school and try to find the box. Fox hunting works by having a device send out a signal, which is picked up by the receivers. The closer the receiver is to the device, the stronger the signal and sound. It works similarly to the radio waves. Satellites and rovers send radio waves for us to pick up and communicate with them. Some galaxies also emit radio waves, which we can detect.

I learnt trigonometry and Pythagorean theorem today, and I was surprisingly able to understand it. With them, we can measure the angle of a stalite from the sun. I can use them to determine unknown lengths in a triangle and use the knowledge to flex on my friends. Using orbital periods, orbital velocity, Kepler's laws and other related equations, you can find the mass of a star.
13/8/25
I learnt about the process in which stars and planets are formed, as well as how to identify exoplanets using things like the Doppler shift and transit. I also learnt how to tell how hot or cold a star is. You can use it to identify the compounds of certain materials for material science or chemistry. You can also use it for imaging for medical purposes.
20/8/25
I learnt about how stars progress after they are formed, as well as what happens when they run out of fuel and die. I also learned about how neutron stars have pulsars and what they can do to the human body. I like today's lesson because we could win candy and there was a booklet. But I think we should get better whiteboard markers because I could barely see what was written on the board. The lesson and slides also changed very fast, so I could not write the notes well.

I learnt more about the sun and its different layers, like the photosphere, corona; the density also decreases as you leave the sun. I also went fox hunting again and was accused of my group mates' wrongdoings. I was surprised that the sun could shoot out CEM strong enough to destabilise our electrical grids for years or even decades, but now strong enough to evaporate us with radiation. I also learnt why auroras are only found in the colder regions.
