Today, I learnt how to use Stellatarium to understand how everything isoriented in space. I also learnt that the axis tilt is 23.5º and I also that longitude and latitude is the RA. I also learnt how the eclipses work, and how and where we can view penumbral and umbral eclipses. I also learnt what is a neutron star, and how they form and what happens when they merge together (black hole).

Today, I did a recap of the earth, moon and sky, and presented it to my Astronomy mates. I also remembered hw to claculate RA and declination, and how the sidereal and solar days are counted, as well as the phases of the moon. Using this knowledge, I sharede it with my friends through Canva, and I hope that I helped in their learning of the subject.

Today, I learnt about gravity and orbits, as well as Keplers 3 laws, and how we can apply them to check for real orbits and impossible orbits, suck as e=0, 1 or e = infinity.
Q1. Scientists use LIGHT YEARS instead of km to calculate space because they want to measure very vast distances in space.
Q2. They are used when needed to measure weight, orbits, and different gravitational field strength of different celestial bodies.

i LEARNT HOW TO CALCULATE RADIATION AND SPECTRA. The presentation was engaging.
Q1. I could convince them that the earth rotates at a constant speed, and that the stars will also orbit and appear at the same time, so I could convince them that since it is so constant and reliable, they can use them to predict natural occurences.
Q2. Radiation can be used to find stars when emission light is detected, proving that radiation levels are present, [proving that a celestial body is present.

Newton had a greater influence towards astronomy because he developed most of the fundamental concepts that helped astronomers to be further informed about why and how the planets were formed, not like Galileo's mere knowledge of what planets existed.

I would add drinking water and more research labs
I can make sure that the atmosphere is significantly thicker by adding more non-lethal greenhouse gases to make the atmosphere thicker to trap heat so that we dont die from freezing :)

They would be built with thermal abilities to keep the same temperature so that we don't die

I recently learned how to use the KSP simulator, which has helped me understand spaceflight, including how to design rockets, launch them into orbit. I also would like more activities in the next session since astronomy now is like all theory no application.

Neutron star anatomy would just be a very destructive star because there are only neutrons and no positrons to cancel the negative charge out.
Red dwarf anatomy's core and radiation zone would be dimmer compared to white dwarf star because white dwarf star is brighter, therefore it needs more nuclear fusion to release more gamma rays and infrared light.
I learnt about star anatomy today and I actually found it helpful that there was a student template. I actually learnt stuff even tho advaith was still kinda boring.
Fox hunting works by using the reciever to intercept radowaves coming from the transmitter. This will be intercepted in the form of beeps/Morse Code(maybe)
Finding like Sun, Black holes, etc.
I learnt how to use the reciever waly talky thingy to recieve radio wave transmissions from the transmitter radio. Using the knobs on the side, I deduced that the radio was tuned to 3.25-3.5MHz to transmit radio waves under FCC regulations. Then after that, I lett the indonesian visitors from PISTD try to locate the transmitter. We only managed to find it once :(
I can find the sine and cosine rule to help with trigonometry in Sec 3 A math
Keplers third law (P² * (M₁ + M₂) = a³)
i learnt sine, cosine and tangent for trigonometry in math and physics, and how to calculate the way the satellite is facing
Yes, it can be applied in plants to find out how much light they absorb and need to photosynthesise and what light it reflects back. It also allows us to see how light is utilised on earth to show temperature. It can also be applied to doppler shift, since it is somewhat audible when something is further away and nearer to something, because of the hertz frequency.
i learnt stellar evolution and recapped the main sequence, as well as nuclear fusion. it was like very fun and like i also learnt how to evaluate a star based on the HR diagram(OBAFGKM) thingy.
ples give more candy next time and do the note = candy thingy. also pls make shiying and pinjing teach AND THADDEUS PLS THADDEUS GOATED frfr

One thing that surprised me the most was the fact that the Zun was 330,000 earths big only. I thought the number was close to or around a million, like 67 million??
We did some fox hunting and then we learnt about our Sun being a garden-variety star, common but useful and found amongst the stars in the main sequence. We also did a quiz to test our understanding of the topic.
