About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.07h 36m 57.22s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.65° 36' 21.53"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Camelopardalis
- DistanceDistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.Approximately 11 million light-years (3.4 Megaparsecs)
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.This image is roughly 3.2 arcminutes (10,000 light-years or 3 kiloparsecs) wide.

A Bright Supernova in the Nearby Galaxy NGC 2403
The explosion of a massive star blazes with the light of 200 million Suns in this NASA Hubble Space Telescope image. The arrow at top right points to the stellar blast, called a supernova. The supernova is so bright in this image that it easily could be mistaken for a foreground...
Galaxy NGC 2403: Before and After Supernova 2004dj Outburst
The image at left represents a small region of NGC 2403, a galaxy located 11 million light-years from Earth. The photo was taken two months before a massive star exploded. The image pinpoints the location of the stellar blast, known as supernova 2004dj, within a cluster of...
