It´s lifespan is 3 to 4 million years with a size that ranges from 1-10 AU. The temperature of the Nebula is really high and right about 10,000 degrees Celsius. Because of this, The Nebula is very bright.What is fascinating about the Nebula is that it is a cluster of old star dust from past dying star and the home to the new stars forming there.The Nebula is important in the Galaxy world due to the chemical evolution it bestows upon itself.]]> 2021-01-22 19:48:45 UTC https://padlet.com/misschang1/7rn9p64f318c98rv/wish/1115669563 https://padlet.com/misschang1/7rn9p64f318c98rv/wish/1115672297 The White Dwarf star is formed after a star fizzles out.
It is considerably smaller than the other stars but keeps the same mass.
It is less bright than the average star but a lot hotter because of how condensed it is.
White Dwarfs will slowly cool until they turn into a Black Dwarf and stop emitting energy.]]> 2021-01-22 19:49:34 UTC https://padlet.com/misschang1/7rn9p64f318c98rv/wish/1115672297 https://padlet.com/misschang1/7rn9p64f318c98rv/wish/1124429534 The red giant is a star that is formed when it runs out of its hydrogen fuel. It can grow up to 100 million to 1 billion kilometers. The stars surface temperature is 3,000-4,000K. Most red giants are still evolving and can become supergiants.]]> 2021-01-25 22:33:56 UTC https://padlet.com/misschang1/7rn9p64f318c98rv/wish/1124429534
