Summary[edit]
DescriptionNGC 5253 - HST - Judy Schmidt.png |
Here we have wide field view of the compact blue dwarf galaxy NGC 5253, and its epic central starburst. It is something like a smaller, but slightly closer version of M82. Though NGC 5253 is less famous than M82 I still find it to be quite interesting—visually stunning, even. An image I submitted yesterday shows a very high resolution close-up of the core: flic.kr/p/WMcktQ flic.kr/p/WMcktQ While this galaxy has been previously processed, I thought it would be better if some older narrowband WFPC2 were used to show off its H-alpha emissions, which are now seen clearly here as a bright pink cloud emanating from around the central area of the galaxy. I tried not to overprocess these clouds, but some might say I have. Still, others may say I didn't take it far enough, because it certainly could be pushed even further. In the upper right and lower left corners are blank areas. I did not want to crop large sections of the galaxy and background off, so I filled these blank areas with a simple noise pattern so that they would not be distracting. H-alpha coverage is incomplete, but close enough that it does not appear to be missing much. Data from the following two proposals was used. I used mosaics from the LEGUS page, as well as the mosaics from the HLA because some parts of the chip gaps in the LEGUS mosaics did not look very good.
