NASA Observation
The galaxy cluster called MOO J1142+1527 can be seen here as it existed when light left it 8.5 billion years ago. The red galaxies at the center of the image make up the heart of the galaxy cluster. This color image is constructed from multi-wavelength observations: Infrared observations from NASA's Spitzer Space Telescope are shown in red; near-infrared and visible light captured by the Gemini Observatory atop Mauna Kea in Hawaii is green and blue; and radio light from the Combined Array for Research in Millimeter-wave Astronomy (CARMA), near Owens Valley in California, is purple. In addition to galaxies, clusters also contain a reservoir of hot gas with temperatures in the tens of millions of degrees Celsius/Kelvin. CARMA was used to detect this gas, and to determine the mass of this cluster. http://photojournal.jpl.nasa.gov/catalog/PIA20052
Scientific Background
This particular celestial object, A Giant Gathering of Galaxies, was captured by NASA's deep space observatories. While its specific historical mythology remains a mystery, objects of this type are crucial for our understanding of cosmic evolution and stellar life cycles.
To observe phenomena similar to this, we recommend using high-contrast filters and a motorized equatorial mount.

Stargazer FAQ
Are the colors in this nebula image real?
NASA often uses 'false color' techniques. Scientists map invisible wavelengths (like infrared) or specific gases to visible colors (red, green, blue) to highlight the nebula's structural details.
Can I see this nebula with a standard telescope?
While some bright nebulas are visible with entry-level telescopes, capturing these stunning details usually requires deep-sky astrophotography equipment and long exposures.
