big bang theory and stars

A cloud of gas and dust where stars are born

A normal star that is undergoing nuclear fusion. Our sun is an example of this.

A star that is much larger than a Sun-like Star; will blow up in a supernova and end as a neutron star or black hole

produces own heat/light, average mass, includes main sequence stars

organizes the family of stars into a diagram; across bottom is star's temperature and side is star's absolute magnitude; a star's temperature and color depend on how big the star is

A massive star that has stopped hydrogen fusion

Creation of energy by joining the nuclei of two hydrogen atoms to form helium.

a large old reddish star that has greatly expanded and cooled as its fuel (hydrogen) has begun to run out

A gigantic explosion in which a massive star caves in and throws its outer layers into space

A huge cloud of gas that is created when a red giants loses all its fuel

the small, dense remains of a high-mass star after a supernova

An object in space whose gravity is so strong not even light can escape.

A small, hot, dim star that is the leftover center of an old star

A white dwarf that has burnt out completely.

The theory that the universe originated in a huge explosion that released all matter and energy.

A point in which matter is infinitely dense, as in the center of a black hole or the universe at the very beginning.

a theory which states that there was no beginning to the universe and that the universe does not change in appearance.

the universe is beginning to expand and is extremely hot

universe is the size of a pea, lots of energy and light. as well as cooling beginning to occur

protons and neutrons begin to form

universe now the size of the solar system

1 trillion, trillion kilometers across in length, at 10 billion degrees celsius

the nuclei of the first three elements form: hydrogen, helium, and small amounts of lithium

atoms finally form as electrons slow down. universe has cooled tremendously

first stars and planets form

An observed change in the frequency of a wave when the source or observer is moving

the change in the wavelength of light due to an object moving away from the observer (red moving away and blue moving towards)

A faint glow of light that fills the universe, falling on earth from every direction with nearly uniform intensity. leftovers from the big bang. cannot be seen.

two most abundant elements in the universe
