An image of the NGC 5353/4 galaxy group made with a telescope at Lowell Observatory in Arizona, USA on the night of Saturday 25 May 2019. The diagonal lines running across the image are trails of reflected light left by more than 25 of the 60 recently launched Starlink satellites as they passed through the telescope’s field of view. Although this image serves as an illustration of the impact of reflections from satellite constellations, please note that the density of these satellites is significantly higher in the days after launch (as seen here) and also that the satellites will diminish in brightness as they reach their final orbital altitude.

 

 

 

Star light, star bright,

First star I see tonight;

I wish I may, I wish I might

Have the wish I wish tonight.

 

 

 

 

 

 

 

 

 

 

That lyric has a number of astronomers wishing away the dawn of all those Earth-orbiting megaconstellations that are dotting the sky today and into the future.

With the advancing StarLink and OneWeb systems, as well as Amazon’s projected Project Kuiper internet network — and other initiatives — there is mounting concern by astronomers of being blinded by the light from an estimated 400,000 recent and planned low Earth orbit satellites.
