This artist's illustration reveals a vast disk of gas surrounding a massive, bright Wolf-Rayet star (shown at center). A close companion star is pulling gas from the Wolf-Rayet, shown by the bridge of bright material connecting the two stars. This act of celestial cannibalism exposes the massive star's hot, helium core. Some of the material, however, is escaping into space, forming the huge disk. This disk structure has never been seen before around a Wolf-Rayet star.

About The Object | |
---|---|
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. |
