P6B3 Life Cycle of the Sun by Ms. Chang https://padlet.com/misschang1/hish6gj5ldnw82z8 From its birth to its death. en-us 2021-01-21 20:00:47 UTC 2026-03-16 00:56:58 UTC hello@padlet.com https://padlet.net/icons/png/2600.png Nebula s1004043787 https://padlet.com/misschang1/hish6gj5ldnw82z8/wish/1115683011 They are huge they are size to 1 AU to 10 AU and they are really bright there SNRS 1-6 and its extremely hot 25,000-100,000 degrees. an interesting fact A dark nebula is so dense that objects behind are obscured. This type of nebula extinguishes light with interstellar dust grains. ]]> 2021-01-22 19:52:44 UTC https://padlet.com/misschang1/hish6gj5ldnw82z8/wish/1115683011 RED GIANT s1004019246 https://padlet.com/misschang1/hish6gj5ldnw82z8/wish/1115714459 This giant fire looking ball is a huge dying star. The helium in the core will run out and fusion stops. The star keeps shrinking until a new helium shell reaches the core. Accorning to scientist in about 5bill. years the sun will begin the helium- burning procces. This star is 100 mil. to 1bill. kilometers in diameter, 62 mill. to 621 mil. miles. It is 100-1000 times the size of the sun. The luminosity of this star is about 3thousand times of the sun.It is 4000 to 5800 degrees fahrenheit.  Extremely bright and hot!! 
*IN A FEW BILLION YEARS OUR SUN WILL TURN INTO A RED GIANT, IT WILL EXPAND AND SWEEP THE INNER PLANETS, MAYBE EVEN EARTH TOO!]]> 2021-01-22 20:02:27 UTC https://padlet.com/misschang1/hish6gj5ldnw82z8/wish/1115714459 s1000284485 https://padlet.com/misschang1/hish6gj5ldnw82z8/wish/1124455014 2021-01-25 22:46:46 UTC https://padlet.com/misschang1/hish6gj5ldnw82z8/wish/1124455014 White Dwarf s1004020202 https://padlet.com/misschang1/hish6gj5ldnw82z8/wish/1124455381 A white dwarf is very dens its mass is comparable to that of the Sun, while its volume is comparable to that of Earth. 
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel.
The first white dwarf discovered was in the triple star system of 40 Eridani.A typical white dwarf has a carbon and oxygen mass similar to the Sun, but is much smaller in size . It is much hotter, but because of its small size its luminosity is low , White dwarf stars can be observed directly through telescopes, though they are extremely faint.white dwarf with temperatures over 180,000 degrees Fahernhite 100,000 degrees Celsius.
 White dwarf can go supernova. Their gravity is 350,000x Earth's. The Sun will one day become a white dwarf. Many will become black dwarfs.
