Sekhar — Aswin

His academic hunger took him far from the tropics. Sekhar earned his PhD from the University of Oslo in Norway—a leap from the Indian Ocean to the Arctic Circle. This transition is crucial to understanding his work. In Oslo, he was exposed to high-latitude astronomy, auroral research, and a deep cultural appreciation for the natural darkness that is disappearing globally.

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? aswin sekhar

Whether you are a student of astrophysics, a policy wonk worried about orbital debris, or simply a human who has looked up and wondered, Aswin Sekhar is a name you need to know. He reminds us that astronomy is not a luxury—it is a planetary defense system, a cultural heritage, and a source of humility all rolled into one. His academic hunger took him far from the tropics

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? In Oslo, he was exposed to high-latitude astronomy,
