What will the Sun end up as when its nuclear energy source dies out forever?
At the mass of the Sun, it will become a white dwarf - and when that one cools down, eventually a black dwarf.
Does the sun create energy with fission or fusion?
The Sun is a GV2 class star, commonly called a "yellow dwarf". The "V" indicates that the Sun is a main sequence star (plotted on stellar color rather than brightness), and like all dwarf stars, its energy is derived from nuclear fusion of hydrogen into helium. The Sun fuses an estimated 620 million metric tons of hydrogen each second in it's core.
What will eventually happen to all energy in the universe?
After about another five billion years, the sun will burn out, and the process of nuclear fusion that has kept the force of gravity from collapsing it will cease to be powerful enough to counter it. The sun will then collapse into a White Dwarf, which is an incredibly dense and comparatively small piece of matter. The white dwarf, will, eventually, cool down into a small, black, non-radiant, cold cinder. The white dwarf is actually extremely dense, with one piece the size of a matchbox weighing in at the same weight as a full-grown African Elephant.
Is a white dwarf star is one that does not have fuel to make is own energy?
That's called a "black dwarf". Such objects are hypothetical; they are not expected to exist yet, since it takes a white dwarf longer, to cool down to a black dwarf, than the current age of the Universe.
Why is solar energy considered a renewable energy source?
Because it can be collected without running out of... sunlight. Many resources like forests, coal, oil, etc. will (in the long run) be depleted. However, we will continue to receive light from the sun for a long time, which is why it is considered renewable. > Not sure it is renewable, its like a big fire, once its fuel is depleted it collapses into a white dwarf. All non renewable sources can be traced back to the suns energy.

How are stars made with fusion reaction big bang giant nebula white dwarf and protostar?
white dwarf is an age that a star reaches but the big bang is an explosion of nuclear energy that makes a star
Explain the role of nuclear fusion in the life cycle of a star?
It's the energy source for all stars (until their fuel is used up - white dwarf stage).
What is plutonium used for and where did it get its name from?
The name plutonium is derived from the name of the dwarf planet Pluto; dwarf planet Pluto is after planet Neptune in the Solar system and plutonium is after neptunium in the periodic table of Mendeleev. Applications of plutonium include: • explosive in nuclear weapons • nuclear fuel in nuclear power reactors (as plutonium dioxide, carbide or MOX) • the isotope 238Pu is used as energy source in spacecrafts or other applications (radioisotope thermoelectric generators); the chemical form is plutonium dioxide. • neutron generator, as Pu-Be source
What produces energy in the Sun alpha reactions proton splitting nuclear reactions or yellow dwarfs?
The energy output of the Sun derives from nuclear fusion reactions. A yellow dwarf is not a process, it's a type of star, of which the Sun is one.
What is the initial source of energy for the collapsing star?
Gravitational potential energy drives the collapse throughout the life of a star, from birth to death.it drives the initial collapse of the nebula into the protostar.it drives the collapse of the protostar into a star, igniting nuclear fusion.it holds the star together against the outward pressure of nuclear fusion.it drives the collapse of the star after nuclear fusion burns out, forming either a white dwarf, a neutron star, or a black hole. depending on its mass before nuclear fusion burned out.
Is white dwarf a dead star?
Yes - in the sense that it no longer produces energy. In other words, the star has run out of fuel for nuclear fusion.
How does a white dwarf produce light and heat?
There is no source of energy heating a white dwarf. The heat is left over from when it was a full-fledged star, like a stone pulled from the coals of a fire. The white dwarf glows simply because it is very hot.
What is A white dwarf which has stopped radiating energy?
Black Dwarf.
White dwarf which has stopped radiating energy?
a black dwarf
Can a white dwarf that has no fuel make its own energy?
No. The energy of a white dwarf is simply residual heat.
When a white dwarf star no longer emits energy what does it become?
A black dwarf.
