Star
How does a star get formed or created?
A star originates from a large cloud of gas. The temperature in the cloud is low enough for the synthesis of molecules.
What can escape a black hole?
Sadly no one escapes the black hole.
About how big are white and black dwarfs?
Name two examples of what can happen after a supernova?
Black hole
Neutron Star
What are stars made out of?
They are made out of gas and dust.
What is the life cycle of a star?
Stars come in a variety of masses and the mass determines how radiantly the star will shine and how it dies. Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula.
What does a star's mass have to do with its lifespan?
A star with less mass lives longer. More mass doesn't live long.
What is a planetary nebula?
Its's a ring-shaped nebula formed by an expanding shell of gas around a old star.
What causes a supernova?
A supernova is caused when a supergiant runs out of fuel and explodes.
Which is bigger, a neutron star, or a white dwarf?
A white dwarf is bigger than a neutron star.
What is a star?
A star is a large celestial object composed of hydrogen and helium that produces electromagnetic radiation through nuclear fusion.
What happens after a supergiants death?
It turns into a supernova:)
What is a white dwarf?
Its a dead red giant that looks illuminated to our point of view.
What is a black hole?
Black hole is a dead super giant that has a huge amount of gravity and its eats anything in its path.
What is nuclear fusion?
Nuclear fusion is the process by which atoms combine to form heavier atoms.
What is the lifespan of a star?
The lifespan of a star only lasts a few thousands of years.
How big is a supernova?
8 times larger than the sun.
What is a black dwarf?
A full on dead red giant.
What is a neutron star?
A neutron star is the extremely dense star that remains after a super giant's death.
Does a white dwarf run on fuel?
A white dwarf doesn't run on fuel.
What are the gases needed to create a star?
Stars are made out of very hot gas. The gas is mostly hydrogen and helium.
Will earth survive then red giant sun?
Earth won't make it out intact.
How long does a giant star's life last?
Estimate about 10 billion years.
About how long does a supergiant star’s life last?
About 10 million years.
Does a black hole have gravity?
Yes a black hole does have gravity.
