A supernova is the explosion of a very large star such that the star becomes extremely bright, perhaps even one billion times brighter than our sun.
In 1054, Chinese astronomers recorded a supernova so bright that it was visible during the day. The explosion left behind a pulsar and a huge cloud of gas and dust known as the Crab Nebula, which still can be seen today. [1]
