Bombardment at Hanle:

The recent launch of low Earth orbit satellite constellations is creating a growing threat for astronomical observations with ground-based telescope, that has alarmed the astronomical community. Observations affected by artificial satellites can become unusable for scientific research, wasting a growing fraction of the research budget on costly infrastructures and mitigation efforts.  The swarm of satellites functioning in low Earth orbit has more than doubled since 2019, when space-based internet initiatives really started to take off. The numbers are pretty staggering. There are some 9,800 satellites in orbit around Earth today, around 7,200 of which are still functioning. By 2030, the number of satellites cluttering low Earth orbit could grow to 75,000, according to the European Southern Observatory. SpaceX alone has plans to launch 42,000 satellites for its Starlink internet service.

Usually during stacking of our Astrophotography Images, the stacking softwares use a special technique called Pixel Rejection method which removes the unwanted satellite trails from our stacked image. But to show the pollution/problem caused by the man-made Artificial Satellites in Astronomy, I have used a special technique to produce this image which was captured during our latest Astrophotography Worksdhop at Hanle, Ladakh. I have stacked the images in normal way to produce the main image and stacked another image to get the Satellite trails. Then I have blended these images together to produce the final image.
