The dusty centre of our Milky Way galaxy from Scutum (top left) to Scorpius (right). Jupiter is the bright 'star' above right of centre.

Rho Ophiuchi is a multiple-star system surrounded by colourful nebulosity. This star-forming region is one of the closest to us at a distance of about 400 light-years. Nikon D7500 + 300mm f/4 lens Mounted on iOptron SkyTracker Exposure = 150 x 60s Acquired 12 June 2024 Processed 4 Nov 2025 |

The image is a star field showing a quasar (a remote galaxy with a bright nucleus) close to the fifth-magnitude star AT Dra. The bottom-left inset shows the camera on a star tracker. The top-left inset shows the camera field of view in the constellation of Draco. The top-right inset shows a blow-up of the centre region of the image. The quasar is the tiny grey dot identified by the two tick marks. The light from the quasar travelled for over 12 billion years on its way to the camera. During that time the Universe has expanded and so the quasar is now 25 billion light-years away. It is receding from us at twice the speed of light. Yes, really.
