An ESO study warns that the proposed launch of over 1.7 million satellites poses an existential threat to astronomy by causing severe light pollution. Researchers are advocating for a strict orbital limit of 100,000 satellites to preserve the viability of ground-based observations.

New research from the European Southern Observatory indicates that massive satellite constellations could damage astronomical research by creating light trails and elevating background sky brightness. Scientists are calling for an orbital cap to protect the ability to observe the cosmos.

A study by the European Southern Observatory warns that the rapid expansion of satellite constellations could render critical ground-based research impossible. Scientists are urging the FCC to implement strict regulatory limits to protect the night sky.
