In a 2024 keynote at the International Astronomical Union (IAU) meeting, he said: "We are the first generation of humans capable of both destroying our planet and protecting it. The telescope is a time machine, but it is also a mirror. When I look at an asteroid, I see a future we can choose to avoid. When I see a satellite streak, I see a future we are sleepwalking into." As of 2026 (the effective context of this article), Aswin Sekhar holds a dual appointment as a researcher at the University of Oslo and a visiting scientist at the Aryabhatta Research Institute of Observational Sciences (ARIES) in Nainital, India. He is currently leading a project called "DarkHeaven" — an initiative to create a low-cost, open-source software package that helps amateur astronomers subtract satellite trails from their images in real time.
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. aswin sekhar
He is also consulting for the United Nations Office for Outer Space Affairs (UNOOSA) on a proposed "Dark and Quiet Skies" resolution. In a 2024 keynote at the International Astronomical
In the vast, silent expanse of the cosmos, threats and wonders often arrive unannounced. While most of us gaze at the stars with casual wonder, a select few dedicate their lives to interpreting their dangerous whispers. One such individual is Aswin Sekhar , an Indian-born astronomer and planetary scientist whose work sits at the critical intersection of astrobiology, asteroid impacts, and the preservation of Earth’s night sky.
