Visualisations of the Milky Way rotation curve, using data from the Gaia mission. Observations are binned into a grid based on distance from the galactic centre and tangential velocity. The lower plot has Sgr A* as the galactic centre, the upper has it twice as far away. Both show the flat asymptote, but there's also a good stream of stars leaving the galaxy. shows the classic flat asymptote.

4x4 grid of images from successive days of Swift observatory observations of GRB221009A. Each shows a bright centre, with a number of concentric, brighter rings. We are seeing X-rays emitted by dust in our galaxy as the gamma-ray burst hit the dust. The images are essentially the same, just each day a little larger, as there has been time for the light to travel a longer path to us. A moon-dog of a gamma-ray burst if you like.
