Andromeda's Colorful Rings The ring-like swirls of dust filling the Andromeda galaxy stand out colorfully in this new image from the Herschel Space Observatory, a European Space Agency mission with important NASA participation. The glow seen here comes from the longer-wavelength, or far, end of the infrared spectrum, giving astronomers the chance to identify the very coldest dust in our galactic neighbor. These light wavelengths span from 250 to 500 microns, which are a quarter to half of a millimeter in size. Herschel's ability to detect the light allows astronomers to see clouds of dust at temperatures of only a few tens of degrees above absolute zero. These clouds are dark and opaque at shorter wavelengths. The Herschel view also highlights spokes of dust between the concentric rings. The colors in this image have been enhanced to make them easier to see, but they do reflect real variations in the data. The very coldest clouds are brightest in the longest wavelengths, and colored red here, while the warmer ones take on a bluish tinge. These data, together with those from other observatories, reveal that other dust properties, beyond just temperature, are affecting the infrared color of the image. Clumping of dust grains, or growth of icy mantles on the grains towards the outskirts of the galaxy, appear to contribute to these subtle color variations. These observations were made by Herschel's spectral and photometric imaging receiver (SPIRE) instrument. The data were processed as part of a project to improve methods for assembling mosaics from SPIRE observations. Light with a wavelength of 250 microns is rendered as blue, 350-micron is green, and 500-micron light is red. Color saturation has been enhanced to bring out the small differences at these wavelengths. |

Special Cases:
About High-Resolution Images For any image which has a "Full Size" download option, that dowload will be the highest available resolution and the widest crop the NASA Herschel Science Center (NHSC) at IPAC has available. Available resolutions can vary widely due to the nature of the images or observations. NHSC opts not to upsource images as better results are usually attained by allowing the graphic designer or printer with the need for the higher resolution to do the upsource. In many cases, screen-resolution counterparts are provided for high-resolution images. These are intended for online viewing and preview, and have not been optimized for print. The NASA Herschel Science Center (NHSC) at IPAC recommends all publications use the "Full Size" images. In situations where a "Full Size" image is not specifically provided on the website, NHSC does not have high-resolution versions of the image available. However, when image credit is given to sources other than JPL/Caltech, high-resolution images may be available through those other institutions, and the user is encouraged to contact them directly. |
