A close-up view of a barred spiral galaxy. Two spiral arms reach horizontally away from the core in the centre, merging into a broad network of gas and dust which fills the image. This material glows brightest orange along the path of the arms, and is darker red across the rest of the galaxy. Through many gaps in the dust, countless tiny stars can be seen, most densely around the core
