what a glorious sun day just today. not a cloud and sky, spring is definitely here. Now Neil, you are a bit of some workship aroud you, you like some betting. I do indeed. I like sitting in my deck chair in the garden, cathcing some race, it look a little bit orange actually. It showed on hand not fake. very cheaky, Robert, very cheaky. Now the reason I am mentioning some betting is what discussing sun in the program. Yes that's right. The sum is on nearly start, althought it's staggering a houndred and fifty million kelometers away. Earth is one of the night planets orbit or circle around the sun. And live on earth couldn't existed without warm and light. And we should mention the sun is absolutely massive. it's volumive, it is so large, it could fit a million earth inside it. That's amazing. It is also incredibley hot. Hotter than anything you can imagine. So Neil can you answer this question how hot is the surface of the sun, now I'll help you out by telling you the sun's core, the center, is blitting five million degreess cesus, but how hot is the sun's surface, is it (1) one point five billion degrees cesus, (b) one point five million degrees cesus or (c) five thousnd five houndred degrees cesus. Hmm, I have no idea. They all quite warm to me. But I think it must be a little cooler than the core, so I am going to go for one point five million degrees cesus. OK, well we will find out if you are right or wrong later on, but now we are listening to professor of solar physics XXXXX to discover what the sun is made of.
It is a big ball gas. And we measure it. it all massive hydrogen. So it's roughly nighty percent hydrogen. a percent helium, the rest of it made up of things like araon, carbon, oxygen, nickel.
So the main gases hydrogen which counting nighty percent of sun's matter. Matter means something that is made of. And Hydrogen create all the sun's energy. Heat and light energy is created all the time in the sun's core. as a result of gases' explosion, or nuclear reaction, and this is a bit hard to believe, it takes a houndred thoudand years to travel from the sun's core, to the sun's surface. But once it reached sun's surface, a photo's fear, it can escape. In fact, it take only eight minutes for the light energy from the sun to reach the earth. Scientists this day are able to see the photo's fear in fantastic detail using powerful telescope. Thought galathere observe that sport from the sun through telescope several hundred years ago, didn't he. Which brings sun another question, how old is the sun? I happen to know, it can it to be around four and half billion years ago. Ha, do you study solar physics in the university, Neil? No, just you know, just general knowledge. Well the sun came into being or was created a very long time ago. We are going to hear now from professor of physics XXXX. What does she said about how long the sun is going to stay the same.
In terms of current life style, it heir through, as long again. throught about half way through and then become the different solar star, become the giant star, and that could be actually. It get a little be warm, a little tostay, I'll getting tho or be nice.
So the sun is going to be the same for another four and half billion years. But the professor also said, the sun will change. When it become ginat star, it will curtain for our planet. And curtain means the end of the fread. Yes, it does. And as a giant star, the sun will get hotter, it will make the earth tostay, now tostay usually means hot in the nice way. that's right. For example, my toast are warmer toasty in my new sleeves, and being reality, the ginat star will make the earth unbarely hot, it will surround and envelope our planet and burn it up. Well, I'm glad it not going to that when that happens. Now remember at the beginning of the show, I asked you how hot the sun's surface is it. XXXXXXXXXXXXXX. It weight you too hard. I am afraid you are wrong. THe answer is actually five thousand and five hundred cesus. But still, if you are planning on visiting the sun, remember the take your sun glasses, plenty of sun screen.
