The Indian astrobiologist who has proposed a systematic study to check for signs of artificial activity in the interstellar object 3I/ATLAS is Pushkar Ganesh Vaidya.  

Key Aspects of the Study

• Researcher: Pushkar Ganesh Vaidya, head scientist at the Indian Astrobiology Research Foundation (IARF).  

• Interstellar Object: 3I/ATLAS, which is the third known object from outside our Solar System confirmed to be passing through.  

• Research Framework: The study proposes an eight-point operational model to analyze measurable indicators that could reveal non-natural, or artificial, behavior. This model aims to replace speculation with observable data.  

• Measurable Indicators: These eight points include checking for:

• Trajectory control (navigational changes)  

• Rotational behavior

• Electromagnetic or thermal modulation

• Environmental perturbations

• Goal: The research defines a falsifiable, data-driven way to test claims of artificial origins for interstellar objects using existing astronomical instruments. It does not claim that 3I/ATLAS is artificial, but offers a scientific method for testing the possibility.  

• Future Mission: This work forms the scientific basis for the Interstellar Object Contact Mission (IOCM-1), a plan to place a small signaling device on an interstellar object like 3I/ATLAS to attempt communication with other civilizations.

Interstellar object 3I/ATLAS to pass by Mars

As the interstellar object 3I/ATLAS moves through the inner Solar System, a new research paper by an Indian astrobiologist has proposed a systematic way to test whether such visitors could show signs of artificial activity.

3I/ATLAS is the third known object from outside our solar system to be discovered from outside our solar system, after ‘Oumuamua’ (in 2017) and 2I/Borisov (in 2019).

Published as a preprint on Zenodo, the research proposed an eight-point operational model for analysing measurable indicators — from navigational changes to electromagnetic emissions — that could reveal non-natural behaviour.

“The approach replaces speculation with observation,” said Pushkar Ganesh Vaidya, author of the paper and head scientist at Indian Astrobiology Research Foundation (IARF).

“Any functioning spacecraft, whatever its origin, must interact with its environment in ways we can detect. Those interactions form the basis of this framework,” he added.

While the paper does not claim that 3I/ATLAS or any other interstellar object is artificial, it defines how such a claim could be tested in a falsifiable, data-driven way using existing astronomical and planetary-science instruments.

Each of the eight points — including trajectory control, rotational behaviour, electromagnetic or thermal modulation, and environmental perturbations — corresponds to an observable signature that ground-based telescopes or spacecraft sensors can examine.

The framework is designed to be repeatable, scalable, and adaptable for future interstellar detections.

The work forms the scientific foundation of the Interstellar Object Contact Mission (IOCM-1) — a plan to place a small signalling device on an interstellar object such as 3I/ATLAS, marking the first deliberate attempt to communicate from Earth to other civilisations via an interstellar messenger.
