Galaxies after all are mostly empty space. Light-years separate stars and if dark dust clouds don’t obscure the view, the galaxies become mostly transparent allowing distant background galaxies to shine through.
Pan to the center of the galaxy and you’ll find a bright star right in the middle. The stars of ESO 318-13 are brilliant in this image but they don’t compare to to the bright star that is actually much closer to Earth within our Milky Way Galaxy. Several bright stars are also members of our galaxy.
ESO 318-13 is an irregular dwarf galaxy millions of light-years from Earth. In this image, we see the galaxy along its edge. Although the stars are brilliant and crystal clear, the beautiful image doesn’t show us much of the galaxy’s structure. We do find many distant galaxies with distinct spiral and elliptical shapes scattered throughout the image.
ESO 318-13 is located toward the southern constellation Antlia, the Pump. French astronomer Nicolas Louis de Lacaille created this constellation in 1756 to commemorate the air pump. The constellation faces away from the Milky Way Galaxy and toward deeps space and has no bright stars.
