He is not anti-technology; rather, he advocates for binding international treaties on satellite reflectivity, maximum numbers per orbital shell, and mandatory deorbiting timelines. "The night sky is a global commons," Sekhar states frequently, "like the high seas or the Antarctic. No corporation should own the view of the stars." In 2020, the world was electrified by the announcement of phosphine gas in the clouds of Venus—a potential biosignature. Aswin Sekhar entered the fray not as a direct discoverer, but as a critical synthesizer. He co-authored papers examining non-biological sources for phosphine (such as volcanic activity or lightning) and challenged the astronomical community to adopt stricter standards for "biogenic claims."
While many astronomers criticize these constellations for ruining photographic images, Sekhar takes a more holistic, almost ecological stance. In his 2023 paper in Nature Astronomy and multiple articles for Scientific American , he argues that we are witnessing "the industrialization of Earth’s orbit without an environmental impact statement." aswin sekhar
Sekhar has coined the term "orbital light pollution" to describe the cumulative effect of satellite trails on professional observatories. His unique contribution is linking this to . He asks: If we cannot see the Milky Way from Earth because of artificial satellites, how will future generations develop a cosmic perspective? How will we detect faint, potentially biogenic signals from exoplanets if our instruments are saturated by reflections from LEO debris? He is not anti-technology; rather, he advocates for
His postdoctoral research took him to institutions across Europe, including the University of Cologne (Germany) and the University of Kent (United Kingdom). This pan-European training allowed Sekhar to develop a rare skill set: he is equally comfortable calculating orbital mechanics for Near-Earth Objects (NEOs) and debating the philosophical ethics of space commercialization. Perhaps Sekhar’s most cited contribution to planetary science involves the 1908 Tunguska event . For over a century, scientists have debated what exactly exploded over the Podkamennaya Tunguska River in Siberia, flattening 2,000 square kilometers of forest. Was it a comet? An asteroid? A piece of a dead planet? Aswin Sekhar entered the fray not as a
In a series of rigorous papers, Aswin Sekhar brought modern computational fluid dynamics and orbital back-integration to bear on the century-old mystery. His work suggested that the Tunguska impactor was likely a low-density, fragile asteroid (a "rubble pile") rather than a comet. More importantly, he modeled how such objects fragment in Earth’s atmosphere—models that now inform planetary defense strategies.
