The double-star system Eta Carinae, about 120 times more massive than the Sun, produced a spectacular outburst that was seen on Earth from 1837 to 1858. This image shows an area near Eta Carinae that is not illuminated by the double-star system's outburst. The image was taken in March 2003 with the NOAO Optical Astronomy Observatory's Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory in Chile.

Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
Object Description | The type of astronomical object. |
R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
Distance | The 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. |
Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
