Merging Galaxies – 6.2 Billion Light-Years from Earth
About the Object
- ConstellationConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.Boötes
- 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.6.2 Billion Light-Years from Earth

This image is a composite of many separate exposures made by the ACS/WFC instrument on the Hubble Space Telescope using two different filters that isolate broad wavelengths. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F555W (V) Green: F555W (V) + F814W (I) Red: F814W (I)

These images from NASA's Hubble Space Telescope show four examples of interacting galaxies far away from Earth. The galaxies, beginning at far left, are shown at various stages of the merger process. The top row displays merging galaxies found in different regions of a large...
Simulated Images of Merging Galaxies
These illustrations demonstrate how two galaxies coalesce in a slow dance that lasts about a billion years. The graphics are taken from a simulation astronomers created to determine how long it takes for galaxies to complete a merger. By understanding the time it takes for two...
