NGC4490 — Image Gallery

DSS Blue

Blue images highlight younger, hotter stars that emit strongly at blue wavelengths.

DSS Red

Red images reveal older, cooler stars and emission nebulae glowing strongly in hydrogen-alpha light.

DSS Near-Infrared

Near-infrared images penetrate dust that obscures visible light and reveal hidden structures.

DSS Composite 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).
