Stars… How stars are made…

The beginning of all starsAll stars off as nebula. These begins are formed of just

cloud and dust that attracts each other. Just like a dust bunny under your bed they cling or stick together forming a larger an larger clump.

If this space mass gets to be big enough it can then start its life through beginning a star or baby star called a protostar.

Protostars A protostar is the first form of a

star. This stage is like the baby stage in a humans life span.

Main Sequence StarThe stars get enough mass to

start fusion. They fuse helium. Most stars in the galaxy are

main sequence stars.

Brown DwarfDoesn't gain enough mass to start fusion. It will stay a brown dwarf forever, it will never be a real star.

Red Gianta

occurs when a main sequence star runs out of

helium and fuses hydrogen instead. Our sun

is a Red Giant.http://en.wikipedia.org/wiki/File:The_sun_in_UV.jpg

Planetary NebulaA red giant stops fusing, forcing the outer layers away.

White DwarfThe leftover core once the star cant fuse anything.

A white dwarf after trillions of years that have cooled off and

you can no longer see.

MASSIVE MAIN SQUENCE

Massive main sequence stars run out of supplied hydrogen much fast than a regular or small main sequence stars.

Red Supergiant

At this point the star has run out of hydrogen an starts to fuse helium and carbon.

The background of this slide is the supernova that a red supergiant made.

SupernovaA supernova is went fusion stops and the star collapses. This explosion admits a huge amount of power. This explosion could give off as much energy as the sun in its entire life span. http://www.spacetelescope.org/images/

NeutronA neutron star is the remaining core of the star. It has a super dense core it can be as small as five miles across in diameter but has a mass of 1.5-2 times the mass of the sun.

Black Hole This is when a massive main sequence star that is 25-50 times the sun colapes into what scientists call a black hole.
