Stargazers are thrilled over the surprise appearance of a star explosion, known as a nova, in the night sky last week, but there is more to this cosmic event than meets the eye.
The new Nova Delphinus 2013 was first spotted in the constellation Delphinus (The Dolphin) by Japanese amateur astronomer Koichi Itagaki on Aug. 14 and quickly confirmed by other skywatchers soon after. Novas are stars that are undergoing a powerful eruption, causing them to brighten significantly, so that they appear suddenly in the night sky where previously no star was visible.
Since its discovery, this nova has brightened rapidly to become an object visible to the naked eye, though stargazers will need to be away from city lights in order to see it clearly
Just how frequently does a nova become bright enough to be seen without the use of binoculars or a telescope?
On average, new novas are detected about once every four or five years. Over the last 112 years, there have been 47 novas that have flared into naked-eye view. The majority of these — 26 — were quite dim and could only be positively identified by using a star chart or sky atlas.
