NASA Observation

The blue dots in this field of galaxies, known as the COSMOS field, show galaxies that contain supermassive black holes emitting high-energy X-rays. The black holes were detected by NASA's Nuclear Spectroscopic Array, or NuSTAR, which spotted 32 such black holes in this field and has observed hundreds across the whole sky so far. The other colored dots are galaxies that host black holes emitting lower-energy X-rays, and were spotted by NASA's Chandra X-ray Observatory. Chandra data show X-rays with energies between 0.5 to 7 kiloelectron volts, while NuSTAR data show X-rays between 8 to 24 kiloelectron volts. http://photojournal.jpl.nasa.gov/catalog/PIA20865

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.
