Space Astronomy Is Under Threat As New Paper "Raises Important Concerns" About MegaconstellationsA picture of the interacting pair of galaxies knwon as the mice, where two spiral galaixes are in the process of merging. One of them has a spiral arm stretched into a long tail. A broad white streak cuts the image, that's the satellite trail.

The Night Sky Is In Danger And Astronomers Are Stepping Up To Protect ItThis photograph shows an edge-on view of the Milky Way’s glowing plane slicing across the night sky, laced by bands of dust and dark gas. Taken with a digital camera using a three-minute exposure, the photograph also reveals a bit of action on the ground. To the left, a vehicle with its parking lights on stops lets out a passenger. Though bathed by the light of the Milky Way, the high-altitude desert remains quite dark. To illuminate the rightward path to the underground entrance ramp of the ‘Residencia’, where staff and visitors stay, the passenger takes along a small flashlight, seen as a squiggly bright line. In the lower right, the glass dome on the Residencia’s roof reflects the starry sky overhead. One of our Milky Way’s galactic satellites, the Large Magellanic Cloud, is seen hanging above the Residencia in the lower right corner of the image.
