Nova in Delphinus constellation

A sixth magnitude nova has been discovered in the constellation of Delphinus by Japanese astronomer Koichi Itagaki. With a pair of binoculars and the finder chart from the S&T website, you should be able to see the nova high in the sky tonight (weather permitting!). It´s about magnitude +5 (see map).

What's a NOVA?

A nova is a cataclysmic nuclear explosion in a white dwarf star. It happens in a tightly-orbiting binary star system in which a normal star pours a stream of hydrogen (accretion) onto the surface of a companion white dwarf. This layer of hydrogen grows thick and ignites, starting nuclear fusion, suddlenly brightening the star. The underlying white dwarf remains intact, and as new hydrogen builds up, the process may repeat.
