The M82 data set is of sufficient signal to noise to permit a maximum likelihood image deconvolution to an effective beam of ∼ 5″. For these regions of very high star formation activity our far-IR images provide an extinction free probe of the source luminosity....
About half of spiral galaxies have a straight structure, called a bar, coming out from the center. The spiral arms attach to this structure. Williams said the commonly held thought is that galaxies form from the inside out. That way, they "get bigger and bigger over their lifetimes." The ...
We present Hubble Space Telescope ( HST ) images obtained with the WFPC2 camera at B & I of a nearly complete sample of ultraluminous infrared galaxies (ULIGs) chosen to have “warm” mid-infrared colors. We find that all of these objects: (1) appear to be advanced mergers; (2) ...
The dataset comprises 200 images of black holes and 200 images of various galaxies in .jpg format. The minimum size of one side is 400, and the maximum is 1200. The dataset is well-suited for a binary classification tasks. Files: BlackHole.rar - 200 .jpg images Galaxy.rar - 200 .jpg...

This lining up of galaxies can be helpful for astronomers performing certain types of research though. “Chance galactic alignments such as this provide astronomers with the opportunity to delve into the distribution of dust in these galaxies,” Hubble scientistswrite. “Galactic dust – the dark te...
Washington (AFP) Dec 12, 2012 - The Hubble Space Telescope is giving scientists a look at the oldest galaxies ever seen, dating back some 13.3 billion years - providing a glimpse into how the cosmos must have looked right after the Big Bang.
