NGC 1313 is an irregular galaxy with an uneven shape and an off-center axis of rotation. NGC 1313 is approximately 50,000 light-years across and is about 15 million light-years away from Earth in the southern constellation of Reticulum.
The starburst galaxy NGC 1313, as imaged by the Gemini South 8-meter telescope in Chile using narrow-band filters in the Gemini Multi-Object Spectrograph. The image is comprised of three color layers: red (ionized hydrogen at 656.3 nanometers), green (ionized oxygen at 500.7 nanometers), and blue (ionized helium at 468.6 nanometers). The field-of-view is about 5.5 x 8.2 arcminutes; each filter was integrated for a total of 600 seconds, and the seeing was about 0.5 arcsecond. The image is rotated counter-clockwise 59 degrees from north up and east left and was produced by Travis Rector, University of Alaska, Anchorage.
