PK 343-00.1 / Nova Scorpii 1437 in the constellation Scorpius
In 1437 Korean astronomers observed a new star in the constellation Scorpio for two weeks. They discovered a nova, a brightness burst in a close binary system consisting of a white dwarf star and its companion. The white dwarf continuously collects hydrogen gas from the companion star. When the collected gas exceeds a certain mass, the nuclear fusion process in the hydrogen ignites abruptly and blasts parts of the collected gas layers into space.
