Gravitational Lens SDSS J1004+4112 – Annotated
About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.10h 4m 11.83s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.41° 12' 50.4"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Leo Minor
- 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.The distance to the galaxy cluster gravitational lens is roughly 7 billion light-years (2.1 Gigaparsecs). The distance to the quasar being lensed is roughly 10 billion light-years (3 Gigaparsecs). The distance to the farthest galaxy being lensed into an arc is 12 billion light-years (3.7 Gigaparsecs).
- DimensionsDimensionsThe physical size of the object or the apparent angle it subtends on the sky.1.9 arcminutes wide

Hubble Captures a "Five-Star" Rated Gravitational Lens
NASA's Hubble Space Telescope has captured the first-ever picture of a group of five star-like images of a single distant quasar. The multiple-image effect seen in the Hubble picture is produced by a process called gravitational lensing, in which the gravitational field of a...
