Poised on the edge of a galactic desert is NGC 6503, a galaxy that appears so alone in the universe that some scientists have called it "lost in space."
The galaxy takes center stage in a new image from the Hubble Space Telescope, which shows NGC 6503 shining in visible and ultraviolet light, with different colors denoting zones of gas and star birth. NASA and the European Space Agency unveiled the image on Wednesday (June 10).
In the image, galaxy NGC 6503 appears to stand alone beside an area dubbed the Local Void, a cosmic dead zone that is at least 150 million light-years across. The galaxy itself is about 18 million light-years from Earth in the constellation Draco. [Latest Photos from the Hubble Space Telescope]
"The galaxy's odd location on the edge of this never-land led stargazer Stephen James O'Meara to dub it the 'Lost-In-Space galaxy' in his 2007 book, Hidden Treasures," NASA wrote in an image description that labeled NGC 6503 "lost in space."
Hubble's image shows a variety of zones within the image, which is about 30,000 light-years across or a third of the size of the Milky Way.
Red patches in the image denote gas, blue contains new stars, and dust lanes (in dark brown) stretch across the lighter arms and center of the galaxy.
The images are based on two sets of observations collected by Hubble, first in 2003 (by the Hubble Advanced Camera for Surveys) and then in 2013 (by the Wide Field Camera 3.) The final image was released on Wednesday.
