What is the primary cause of a nova explosion?

The fusion of hydrogen on the surface of a red giant, resulting in a sudden increase in brightness.
The collision of two white dwarfs leading to a powerful release of energy.
The rapid collapse of a red giant star.
The accumulation and subsequent explosion of material from a red giant on the surface of a white dwarf. (correct)

Why is the upcoming nova outburst of T Coronae Borealis considered a rare event?

It occurs in a triple star system, which is unusual.
It leads to the complete transformation of a star to a different type.
It involves a black hole binary system, which is exceedingly rare.
It will be visible to the naked eye, unlike typical novae. (correct)

Which of the following celestial bodies are directly involved in a nova event?

A red giant star and a white dwarf. (correct)
Two equal sized stars rapidly rotating around each other.
A main sequence star and a black hole.
A neutron star and a planetary nebulae.

What is a nova?

A sudden and dramatic increase in brightness caused by the explosion of material gathered on the surface of a white dwarf.

How do novas occur?

A binary star system contains a red giant and a white dwarf. The red giant sheds material onto the white dwarf. Eventually, the collected material explodes, creating the nova.

Visibility of novas

Typically they require a telescope to be seen, but the upcoming T Coronae Borealis nova will be visible to the naked eye.
