Fusion is happening deep inside a star, not near its photosphere (commonly called the star's surface because we see it, a star is just a ball of gas contained by gravity and has no actual surface). The photosphere is just hot enough to glow in visible light. A sunspot is a colder area in the photosphere that does not glow as brightly (and thus looks like a dark spot) because of a sort of "magnetic storm" occurring there. Sunspots always occur in pairs: one a north pole and one a south pole. There is a magnetic flux loop connecting the pair and sometimes a solar flare following the flux lines. If the flux lines "brake" the flare will be ejected away from the star into space. These ejected flares cause the auroral displays, communications interruptions, and occasionally electrical blackouts.

Can planets generate nuclear fusion?
No. That's precisely the main difference between planets and stars - that stars can have nuclear fusion, planets not.
What isdifference nuclear fission and nuclear fission?
The difference between Fusion and Fission is that Fission is easier to do and produces more energy than fusion reactions. However fission can be dangerous and is used in Nuclear reactors. Fusion however is safer and produces less energy but safely. It is quite difficult to cause a Fusion reaction however.
What is the difference between hot nuclear fusion and cold nuclear fusion?
"Hot" nuclear fusion (this is not the term normally used) is exactly what the name implies, the materials are heated, which provides them with enough energy to overcome the normal repulsion of protons. Cold nuclear fusion requires no heating and has not yet been proved, although dozens of Physicists and Electro-Chemists have claimed to have created cold fusion. Cold Fusion relies on other forces, such as pressure, to overcome the electrostatic force of repulsion.
What is the difference between a star and a firefly?
A star is a gigantic flaming ball of gas fueled by nuclear fusion. A firefly is a small insect.
What is the difference between nuclear fision and nuclear fusion?
fission is breaking big things up into smaller ones. fusion is joining little things together into bigger ones.
Can planets generate nuclear fusion?

What is the difference between the sun's energy and a nuclear power plant?
the sun is powered by fusion, the power plant by fission
What is the difference between intertransverse fusion and lateral transverse fusion?
Is this a medical question? I don't recognise the terms in nuclear energy This a medical terminology question. Sorry about that
What is the difference between a bioreactor and nuclear reactor?
A nuclear reactor uses either nuclear fission or nuclear fusion to generate electricity, while bio-reactors use the excretions of many animals to generate electricity.
What is the difference between a atomic submarine and a nuclear submarine?
Nothing but the terminology. "Atomic" was the term used in the early days of nuclear weapons and nuclear power. "Nuclear" (describing the fission process of nuclear power and nuclear weapons) became the term when fusion bombs became reality, as Atomic can refer to both fission and fusion processes.
