Our First Step into Asteroid Research
In 2021, CSTERC Techno Science LLP, in collaboration with the International Astronomical Search Collaboration (IASC), took an important step towards bringing authentic astronomical research closer to students in Tamil Nadu.
The inaugural edition of the Tamilnadu Asteroid Search Campaign was designed not merely as an astronomy awareness programme, but as an opportunity for students to experience how scientific research is actually carried out.
Our vision was simple: students should not only learn about astronomy—they should have an opportunity to contribute to it.
Through this initiative, teachers from government schools were introduced to asteroid searching using real astronomical data and guided to engage their students in a structured citizen-science research programme.
Training Teachers for Real Scientific Research
As the first step, 10 teachers from government schools across Tamil Nadu were selected and trained to participate in the asteroid search programme.
The training introduced the participating teachers to the fundamentals of asteroid detection, the principles behind identifying moving objects in astronomical images, and the process of analysing observations supplied through the IASC programme.
The teachers then carried this experience back to their schools, where they engaged their students in the asteroid-search activities.
This teacher-led approach was particularly important to us. Instead of limiting the programme to a one-time workshop, we wanted to create a pathway through which scientific research could reach classrooms and encourage students to think and work like researchers.
Searching the Sky Through Citizen Science
The participating teams worked with astronomical image data provided through the IASC campaign and carefully examined image sequences to identify objects that appeared to move against the background stars.
Asteroid searching requires patience, attention to detail and scientific reasoning. Participants had to distinguish potential moving objects from image artefacts, background objects and other sources of false detections.
For the students and teachers involved, this was a completely different experience from learning astronomy through textbooks alone.
They were working with real astronomical observations as part of an international citizen-science research programme.
40 True Signatures Identified
The inaugural campaign produced an encouraging outcome.
The participating teams successfully identified 40 true asteroid signatures during the campaign.
Among these, 18 signatures were categorized as Preliminary Detections, indicating that they had a stronger possibility of being genuine asteroid detections and therefore warranted further scientific consideration.
For a first campaign involving teachers from government schools, these results represented a significant achievement.
More importantly, the campaign demonstrated that students and teachers, when given the right training, mentorship and access to scientific datasets, could actively participate in meaningful astronomical research.
Connecting Tamil Nadu Classrooms with Global Astronomy
The programme also created an important connection between local classrooms and the wider astronomical research community.
The International Astronomical Search Collaboration (IASC) provides students and citizen scientists with opportunities to participate in professional-quality asteroid searches using astronomical data. Through this collaboration, the Tamilnadu Asteroid Search Campaign became part of a much larger international effort to identify and track small Solar System bodies.
The association with an international programme connected to NASA added another dimension to the experience. For participating teachers and students, the certificate they received was not simply a recognition of attendance—it represented their participation in an international citizen-science research initiative.
Recognizing the First Participants
At the conclusion of the campaign, all 10 participating teachers were recognized with certificates from IASC for their participation in the asteroid search programme.
The recognition was an important moment for the teachers who had taken the first step into this new area of scientific engagement and, through their classrooms, opened the door for their students to experience astronomy as a research activity.
Their participation laid the foundation for what would later become a continuing effort to introduce asteroid research and citizen science to more students and schools across Tamil Nadu.
More Than an Asteroid Search
The 2021 campaign was ultimately about more than finding asteroids.
It was about changing the way young people experience science.
Instead of asking students to simply read about discoveries made by scientists around the world, we wanted them to ask:
“Can I be part of the discovery?”
The Tamilnadu Asteroid Search Campaign showed that the answer could be yes.
By training teachers, engaging students, providing access to real astronomical datasets and connecting classrooms with an international research programme, we took our first major step towards creating a culture of research-based astronomy education and citizen science in Tamil Nadu.
The 40 true signatures and 18 preliminary detections became more than numbers in a campaign report. They became evidence of what can happen when young learners are given the opportunity to look at the universe not merely as spectators, but as participants.
The Beginning of a Continuing Journey
The inaugural Tamilnadu Asteroid Search Campaign in 2021 became an important milestone in the journey of CSTERC and Open Space Foundation towards building research-oriented astronomy programmes for students.
What began with 10 teachers and their students would inspire subsequent asteroid-search campaigns, wider school participation and a continuing effort to make authentic astronomical research accessible to young learners.
For us, the 2021 campaign established an important principle that continues to guide our work:
Science education becomes more powerful when learners are given the opportunity to participate in science itself.
The sky was no longer something our students simply observed.
They had begun to search it.
