A new star burst into view in the constellation Delphinus earlier this month.
The explosion of a white dwarf star created the brightest nova since 2007, Sky & Telescope reports.
A spectral analysis of the star, now known as Nova Delphini 2013, shows a pattern typical for material blasted from a type of cataclysmic binary system called a "classical nova," NASA added.

This type of object is the result of powerful explosions on the surface of a white dwarf star, which remains intact.
Compare that to supernova explosions, which are triggered when a white dwarf pulls just enough material from its partner star to set off a "massive thermonuclear explosion that blows the entire white dwarf to smithereens," Sky & Telescope said in a press release.

Nova Delphini 2013 can be seen in the eastern sky in the early evening. Sky-watchers in dark locations away from city lights should be able to see it with the unaided eye. For more urban dwellers, binoculars may be of use.
