Spectacular Astronomy Image Mosaics and a New Astronomy Blog

This week, a new astronomy blog was released. It is called the “Montage Image Mosaic  Software” blog. The Montage team (of which I have the privilege of being a member) will be blogging about how Montage is used in scientific analysis and generating new science products, showing images derived with it, posting tips for getting the most out of the toolkit, entertaining suggestions for new functionality.

I am not one for re-blogging, but I will relent on this one occasion. Astronomers have generated some superb image mosaics with Montage, and this post, taken from the Montage blog, shows some of my favorites.

This three-color mosaic of the Pleaides was computed by Dr. Inseok Song.

The SBb LINER galaxy NGC 1097 is a spectacular face-on galaxy. The data in this mosaic were measured with the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope.

The gray scale in this continuum-subtracted H-alpha image mosaic of the supernova remnant S147 shows extraordinary details of the interaction of the ejecta with the interstellar medium.

Finally, this four-color mosaic of a section of the galactic plane was composed as part of the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire (GLIMPSE) project.

Additional mosaics made with Montage are posted in the gallery of the Montage Web site.
