where is a star born
a nebula
100
How are stars powered
by nuclear fusion in their cores, mostly converting hydrogen into helium.
100
What is the closeest star to us
the sun
100
How long does the Sun live for
10 billion years
100
What is a red giant
is a relatively old star whose diameter is about 100 times bigger than it was originally, and had become cooler
200
What is a supernova
a bright star
200
What is the fate of a star
A star will become either a black dwarf, neutron star, or black hole, depending on how massive it was. .
200
What is a galaxy
huge group of stars, dust, gas, and other celestial bodies bound together by gravitational forces
200
What are Sun-like Stars
(Mass under 1.5 times the mass of the Sun) --> Red Giant --> Planetary Nebula -->White Dwarf --> Black Dwarf
200
What is the Sun a Dwarf star?
yes
300
As the nuclear fuel runs out (in about 5 billion years), the star expands into what
a black dwarf, neutron star, or black hole
300
what is a nebula
is a huge, diffuse cloud of gas and dust in intergalactic space. The gas in nebulae is mostly hydrogen gas (H2).
300
What is the supernova inside Orien
BETELGEUSE
300
What are Giant Stars
(Mass over 3 times the mass of the Sun) --> Red SuperGiant --> Supernova --> Black Hole
300
What is a neutron star
is a very small, super-dense star which is composed mostly of tightly-packed neutrons.
400
How does a star form
A star is formed out of cloud of cool, dense molecular gas.
400
What is a Crab nebula
a cloud of intergalactic gas and dust. It is the remnant of a supernova
400
What is the big dipper
a constellation with 7 stars
400
what are the last stages of a star
black dwarf, neutron star or blackhole
400
why do stars twinkle?
Stars twinkle when we see them from the Earth's surface because we are viewing them through thick layers of moving air in the Earth's atmosphere.
500
What is a binary star system
What is a binary star system Two stars that are locked in elliptical orbit around their center of mass
500
how does a star die out
Stars expand as they grow old. As their core runs out of hydrogen and then helium, the core contacts and the outer layers expand, cool, and become less bright. This is a red giant or a red super giant (depending on the initial mass of the star). It will eventually collapse and explode. A star's life span and eventual fate are determined by the original mass of the star.
500
What are the 12 zodiac constellations
What are the 12 zodiac constellations Aquarius, the water bearer Aries, the ram Cancer, the crab Capricorn, the goat Gemini, the twins Leo, the lion Libra, the scales Pisces, the fish Sagittarius, the archer Scorpius, the scorpion Taurus, the bull Virgo, the virgin
500
What are Huge Stars
(Mass between 1.5 to 3 times the mass of the Sun) --> Red SuperGiant --> Supernova --> Neutron Star
