NGC3521 Image Gallery

DSS Blue

These images are valuable for highlighting the presence of younger, hotter stars, which emit more light in the blue wavelengths.

DSS Red

These images are excellent for detecting older, cooler stars, as well as emission nebulae, which glow primarily in the red due to hydrogen alpha emissions.

DSS Near-Infrared

These images can penetrate dust clouds that obscure visible light, revealing structures and objects hidden within.

DSS Composite image

DSS Color images are composite images created by combining the blue, red, and often near-infrared images to produce a full-color representation.

The photos are taken from the Digitized Sky Survey 2 (DSS2), which was produced at the Space Telescope Science Institute (STScI) under NASA contract, using data from the UK Science and Technology Facilities Council (STFC), the European Southern Observatory (ESO), and the National Geographic Society-Palomar Observatory Sky Survey (POSS II).

Special thanks to the National Optical Astronomy Observatory (NOAO), the Royal Observatory, Edinburgh, and the California Institute of Technology for their significant contributions.
