IC4604 — Image Gallery

DSS Blue

IC4604 — blue-filter image
Blue images highlight younger, hotter stars that emit strongly at blue wavelengths.

DSS Red

IC4604 — red-filter image
Red images reveal older, cooler stars and emission nebulae glowing strongly in hydrogen-alpha light.

DSS Near-Infrared

IC4604 — near-infrared image
Near-infrared images penetrate dust that obscures visible light and reveal hidden structures.

DSS Composite Image

IC4604 — composite color image
DSS color images combine blue, red and often near-infrared exposures into a composite view.

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

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