About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.13h 11m 34.19s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-1° 21' 56.0"
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Virgo
- 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 lensing cluster is 2.2 billion light-years (675 megaparsecs).

Galaxy Abell 1689's "Gravitational Lens" Magnifies Light of Distant Galaxies
A massive cluster of yellowish galaxies, seemingly caught in a red and blue spider web of eerily distorted background galaxies, makes for a spellbinding picture from the new Advanced Camera for Surveys aboard NASA's Hubble Space Telescope. To make this unprecedented image of the...

Gravitational Lens Arcs in Galaxy Cluster Abell 1689
A selection of cropped images from a NASA Hubble Space Telescope Advanced Camera for Surveys view of one of the most massive galaxy clusters known, called Abell 1689. These close-ups show "lensed" images of background galaxies that have been brightened and smeared by the...

Gravitational Lensing Illustration
Simulation of a gravitational lens moving across the Baltimore City skyline. The lens is produced by a compact and massive object, which bends space around it. This distorts light coming from any object behind the lens. The simulation shows how the lens distorts the background...
