We Are Stardust

We are all star dust, literally. You are a star! So am I, so is everyone else and everything you see. We all came from stars. They were the furnaces that produced the ingredients of life and everything else on Earth. Here is how:

Now to put a perspective on how big these furnaces are:
 
And lastly, for some light entertainment!

What have you found out about stars that is interesting? Where do they come from? How long to they last? What happens when they die? What is going to happen to our sun?

By the way, if you want to see some incredible pictures of our universe/space/etc check out NASA's Astronomy Picture of the Day.

  1. The temperature of a star is defined by its mass. So this means that the more mass the star has, the larger the star’s core is, and the more nuclear fusion can be done at its core. With this being said, the energy can reach the surface of the star, thus allowing the increase of the star's temperature.

  2. Every star begins life as a potostar. They also follow the main life cycle of a star, but depending on the mass and other factors, it could become a red gianor supergiant. From there, it could become a white dwarf or black hole depending on the size of the explosion.

  3. Stars are not all the same color. Their color is determined by their temperature. If we know their temperature, then we know it's size, and if we know its size, then we know what it is capable of.

  4. Planets are formed by either gravitational collapse, as in the formation of stars, or accretion. Accretion is when a massive object's gravity attracts more matter, typically gaseous matter in an accretion disk.

  6. The sun is extremely small compared to other stars. The star Antares is incredibly large compared to our Sun. This photo provides a great refernce point: http://www.brevardastro.org/albums/UniverseScale/photo5.html
    Also, the lumosity (brightness of a star) is dependant on the mass of a star. lumosity=mass^3.

  7. Every star you see in the night sky is bigger and brighter than our sun

  8. There are more stars than all of the grains of sand on earth. You can see at least 20 quadrillion miles in the galaxy.

    Next year a giant gas cloud will collide with the black hole in the center of our galaxy. This collision will be visible from earth's sky.

  10. A blackbody absorbs all the radiant energy that hits it, but does not forbid it from re-emitting the energy. In the case of a star, it absorbs all radiation that falls on it, but it also radiates back into space much more than it absorbs. Thus a star is a black body that glows with great brilliance!

  11. Massive Stars in the milky way are apart of stellar duos. One of the stars in the duo sucks Gas from its other counter part and these parings are called Vampire Stars.

  14. •Stars that have really strong gravity become smaller and smaller with time and eventually, turn into black holes.

  15. The color of the star can tell us how hot or cold the star is. The hottest stars have a bluish color and the coldest stars have a reddish color.

  16. The stars do not twinkle on their own power, but the earths atmosphere causes the twinkling to occur. There are two theories; the first is... As pockets of air move around, it causes light to be uneven, causing relative brightness and dimmness. The second theory is that something on the edge of the solar system causes the twinkling to the stars but not the sun, moon, or satillites because they are much closer to us. #Boom http://scienceblogs.com/startswithabang/2009/07/29/why-do-stars-twinkle/

  19. The larger the star's mass, the shorter its life will be.

  20. Stars are cosmic energy engines that produce heat, light, ultraviolet rays, x-rays, and other forms of radiation. They are composed largely of gas and plasma, a superheated state of matter composed of subatomic particles.

  21. A star the size of the Sun requires 50 million years to mature from its initial collapse to its adulthood.
