layers of our sun
the hottest and center point of our sun
what is the core
the first step in the formation of a star; a cloud of dust and gas that needs a force or disturbance to form a star; composed mostly of mostly hydrogen and helium
what is a nebula
the color of stars with the lowest temperature range
(<3,500 degrees Celcius)
what are red stars
a massive celestial body that is made of gas and emits light and electromagnetic energy
what is a star
"moon" in Latin
what is luna
the two closest layers to the center of our sun
what is the radiative zone and convective zone
second step in the formation of a star; a flattened disc of gas with a large concentration of matter
what is a protostar
the color of stars with the second lowest temperature range
(3,500-5,000 degrees Celcius)
what are orange stars
how much energy is released per second from a star
what is luminosity
what is stella
the 4th layer of our sun from the center (is the reason we see our sun as white/gives it color)
what is the photosphere
the 3rd stage of life of a star that is caused by nuclear fusion generating more energy and heat to be released, causing the star to expand, and eventually reach a stable size; can last between 10 million and 10 billion years
(our sun is in this stage)
what is main sequence
the temperature range of yellow stars (Celcius)
what is 5,000-6,000 degrees Celcius
the diagram that tells us how hot, luminescent, and bright a star is
(most follow a diagonal path)
what is the Hertzsprung-Russel diagram (H-R diagram)
"sun" in Greek or Latin
what is Helios or sol
the 5th layer of the sun from the center
what is the chromosphere
the 4th stage of most stars; forms after gases on the surface of the star leave and the core heats the gases that are left; surrounds a dying star
what is a planetary nebula
the two star colors that have the same color in their name, yet are vastly different temperature ranges
(6,000-7,500 and 10,000-30,000 degrees Celcius respectively)
what are yellow-white and blue-white stars
what is 300,000 km/sec
this is what makes comets look bright
what is sunlight hitting the coma
the 6th and outermost layer of the sun
(hint: 2020)
what is the coronasphere
the 5th stage of most stars; the surrounding gases leave and any matter left is condensed and compressed because of gravity; forms another kind of very hot and dense star
what is a white dwarf
the color of stars with the highest temperatures
(+30,000 degrees Celcius)
what are blue stars
(hint: 4.2 light years away)
what is Promixama / Alpha Centuria
this causes the tail on comets
what is the ice turning into gas because of the sunlight
