While a Nova only increases in brightness when it reignites, a Supernova does not merely reignite, but explodes as the star reaches the end of its life. However, during a solar eclipse the moon (instead of the Earth) blocks the sun as it passes in between the sun and the Earth. A total solar eclipse occurs only when there is direct alignment of the sun, the moon and the Earth while a partial lunar eclipse occurs when there is a near direct line.
