That Starlink Problem Astronomers Were Worried About Is Totally Happening

For the modern astronomer, satellites are just a part of life. There are more than 2,000 active ones currently orbiting Earth, and the smartest minds in space photography have managed to work out clever ways of removing the occasional fly over from their images of space.
But then there's Starlink. The first stages of SpaceX's plan to launch up to 42,000 satellites to provide Earth with complete internet coverage have clocked in at 122 objects so far; after the first major launch in May, astronomers were worried.

Now a second launch has occurred, and their concerns have truly started to materialise.

In the early hours of the morning on November 18 at the Cerro Tololo Inter-American Observatory (CTIO) in Northern Chile, the trail of newly launched Starlink satellites flew overhead, absolutely filling an image taken by the Dark Energy Camera (DECam).
Each one of those dotted line trails in the image below is a Starlink satellite.
