Lee said "Yes i am fine!" to Kass and then turned to the flying note, it wasfrom Erica. Instead of replying to it he placed it in his pocket. OOC ~ i am trying to shorten this because we cant have the whole lesson filled up with our conversation. We can talk in the hallways afterwards |
"well ok" she sadi sitting back in her seat thinking she was upsetting him. she took out a books a started to write in it making sure no one could read it. ooc:that is a good idea |
Evy entered the classroom and took her usual seat near the window. |
Hello hello! Welcome to the class! Now this lesson is going to be used for two things. First we will talk about the sun, the closest star to us, then we are going to have that discussion that you all wanted to have, about wizard and muggle astronomy. First! Can anyone give me any serious or funny names for the sun. The better it is, the more points you get... |
Francis smiled and raised her hand, "The burping gas... The spotted teenager.. The ionized ball.. The gravitational furness.." |
Luna raised her hand, "I've heard the sun reffered to as 'the big ball of burning gas' by some muggles. Not that humorous, but if you think about it right, it is funny. It was also referred to as 'king of the sky' by the ancient japanese. |
Meghan snorted and raised her hand. "My grandma calls in 'that great big bright ball in the sky'". |

Keep em comin! |
Selena raises hand "My grands calls it the fountain of fire." |
Mithos raised his hand "The great luminaries of heaven, Cheese Burger Nebula, Cleopatra’s Eye, Cygnus Egg, Burning Sunflower.." |
*counts with fingers* "Photosphere, main sequence star, giant fireball, lava(magma) ball, hydrogenball, egocenteric body, please-do-not-stare-directly, and once... Polka-dotted jam." |
Deep in thought as she listened to the other students reponses, Kay suddenly raised her hand. "I have heard the Sun refered to as 'a great ball of fire in the sky.' I have read that the Ancient Egyptians worshipped the Sun, or the Aton. Somewhere I have also read that there are 12 names for the Sun in the Surya Namaskar, or sun salutation, that is practiced by the Hindu. The names are Mitra, Ravi, Surya, Bhanu, Khaga, Pushna, Hiranya Garbha, Maricha, Aditya, Savitra, Arka, and Bhaskara." |
Humungo-radiant energy-ball-of-hydrogen-and-helium-and-a-lot-of-other-cool-gases-source-of-heat-and-light-and-only-93 million miles-away-from-Earth-and-has-a-mass-330,000-times-bigger-than-us-type-of-star-thing. Made the word up my self. Here's another name... "Mr. Sun, Sun, Mr. Golden Sun, hiding behind the tree..." Barney song. :stab:. "Somethin' Somethin' come out and play with me. Mr. Sun, Sun, Mr. Golden Sun," Gotta love it. |
Anila laughed out loud at the Hufflepuffs answer. "Sun, Sun Mr. Golden Sun, please shine down on meee," she finished. Honestly, she had no idea where these people learned all these names...mostly she just called it the sun... |
Evy raised her hand. She was bored. "In French it is Soleil. Let's see... Fire Ball, Brilliant Star, Solar Disk, Lord's Day, Sunlight, Sunshine, Fiery Flower... No more ideas." |

Sorry guys but du to an emergency I have to delay the class for a day. I'm sorry. Will be opened back up sat night my time. Sorry! |
Sorry bout that! Ok so, if you think of any more names please post em. How old do scientists estimate the sun to be? |
Lita raise her hand. "I beleive it is around 5 billion year, for what they think." |
*raise hand* The Sun formed about 5 Ga (5 billion years) ago, as determined by nucleocosmochronology. |
That's right! And how long do they think it will keep burning? |
Lita raised her hand yet again. "Some where around 5 billion more years, since they think its life span, since its a normal sized star is 10 billion years, that would make it in the middle of its cycle." She answered, astronomy being her fave subject, she loved stars. |
*ponders* Well, the Sun does not have enough mass to explode as a supernova. Instead, in 4-5 billion years it will enter its red giant phase, expanding as the hydrogen fuel in the core is consumed. Then it will start to fuse helium and the core temperature will rise to 3×108 K. While it is likely that the expansion of the outer layers of the Sun will reach the current position of Earth's orbit, recent research suggests that mass lost from the Sun earlier in its red giant phase will cause the Earth's orbit to move further out, preventing it from being engulfed. Following the red giant phase, giant thermal pulsations will cause the Sun to throw off its outer layers forming a planetary nebula. The Sun will then become a white dwarf, slowly cooling over eons. |
Rosa raised her hand: 'how about pimple-ball?' she asked |
Sabina continued to take notes as some students answered the professor's question. |
Francis raised her hand, "The sun is a G2 on the main sequence, which usually have a lifetime of about 10 billion years (10 Ga). Since the Sun formed about 5 Ga (5 billion years) ago, which has been determined by the use of nucleocosmochronology, the Sun has about 5 billion years to go". |
