Core details of starburst galaxy NGC 1313, also called the Topsy-Turvy Galaxy. The very active state of this galaxy is evident from the image, showing many star formation regions. A great number of supershell nebulae -- cocoons of gas inflated by successive bursts of star formation -- are apparent. The green nebulosities are regions emitting in the ionized oxygen lines and likely contain very hot star clusters. The galaxy was discovered in 1826 and is now estimated to be about 13 million light-years distant.
Using both ESA/ESO/NASA provided software and Photoshop I combined seven b&w images (courtesy ESO) – four with wideband visible light filters and three with narrowband filters extending into the near infrared -- with their Very Large Telescope in Chile and processed them to create this image.
