A nova is a sudden, bright explosion of light from a white dwarf star in a binary star system. It occurs when the white dwarf pulls material from its companion star, causing a nuclear reaction that results in a sudden burst of energy and light.
A supernova is a much larger and more powerful explosion than a nova. It occurs when a massive star reaches the end of its life and collapses, releasing a huge amount of energy and creating elements heavier than iron. A nova is caused by a different process and is much less powerful.
Yes, some novae can be seen with the naked eye. However, they are not as bright as supernovae and may only be visible for a few days or weeks.
On average, a nova occurs in our galaxy about once every year. However, they are often not visible to the naked eye and may only be detected by telescopes.
No, neither novae nor supernovae pose a threat to Earth. They are usually too far away and the energy and particles they release are not strong enough to reach us. However, a nearby supernova could potentially affect the Earth's ozone layer and atmosphere.
