Sometimes, when people cannot come to astronomy, astronomy has to find a way to come to them.

December 2020 was a difficult time for the world.

The COVID-19 pandemic had changed the way we lived, travelled, learned and connected with one another. Public gatherings were restricted, schools and institutions were closed, and even something as simple as gathering a group of people around a telescope was no longer possible.

But the night sky did not stop.

On 21 December 2020, Jupiter and Saturn were set to meet in one of the most remarkable celestial events of our generation — the Great Conjunction.

Jupiter and Saturn pass each other in our sky roughly once every 20 years. But the 2020 event was exceptionally close. The two planets appeared only about 0.1 degrees, or 6 arcminutes, apart — their closest apparent conjunction since 1623. It was also the closest easily observable conjunction of the pair in centuries.

For astronomy enthusiasts, this was an event not to be missed.

For us, there was one problem.

How do we share it with people when we couldn’t bring people together?

The Telescope Moved Upstairs

Before the pandemic, one of the simplest and most powerful ways we introduced people to astronomy was by taking a telescope to them.

A telescope in a school courtyard.

A telescope at a public gathering.

A telescope under the night sky surrounded by curious people asking questions.

But the Great Conjunction of 2020 arrived at a time when that was simply not possible.

So we changed the approach.

Instead of taking our telescope to a crowd, we took the telescope to our apartment terrace.

We set up the telescope on the terrace, pointed it toward the southwestern evening sky, connected a camera to the telescope and created a live feed through our YouTube channels.

The idea was simple:

If people couldn’t gather around our telescope, we would bring the telescope to their screens.

That small decision became something much bigger for us.

Bringing a Rare Sky Event to the Screen

As Jupiter and Saturn appeared together in the telescope’s field of view, the camera allowed viewers to experience the event remotely.

But we didn’t want the livestream to simply be a telescope camera pointed at the sky.

We wanted it to be an astronomy session.

During the live broadcast, we explained what was happening in the sky, why Jupiter and Saturn appeared so close, what makes a conjunction different from an actual meeting in space, and why the 2020 event was so special.

And importantly, we did it in both Tamil and English.

For us, science communication was never supposed to be limited by language.

Astronomy belongs to everyone.

A child watching from home should be able to understand what they were seeing. A parent who had never used a telescope should be able to follow the explanation. An astronomy enthusiast should be able to appreciate the science behind the spectacle.

The telescope was providing the view.

The conversation was providing the understanding.

A Different Kind of Community Outreach

The Great Conjunction was more than an observation session for us.

It became one of our earliest experiences of digital astronomy outreach.

Until then, community astronomy was largely something we imagined happening physically — people gathering around a telescope, taking turns at the eyepiece, asking questions and sharing the excitement of discovering something in the sky.

The pandemic forced us to rethink that model.

The terrace became our temporary observatory.

The telescope became a broadcast instrument.

The camera became the bridge between the sky and the audience.

And the internet became the space where our astronomy community could gather.

That evening taught us an important lesson:

Community outreach doesn’t always require a physical gathering. It requires a willingness to connect people with science.

One Evening, One Telescope, A Bigger Beginning

Looking back, the Great Conjunction of 2020 remains one of those evenings that feels much bigger than the equipment we used or the platform on which we streamed it.

It was a memorable evening because we were watching something that had not appeared this close in the sky for centuries.

But it was also memorable because it showed us what was possible.

We could observe.

We could explain.

We could broadcast.

And we could reach people beyond the physical location of our telescope.

That experience became an important stepping stone in the evolution of CSTERC’s community outreach efforts.

What began with a telescope on an apartment terrace would eventually grow into a broader vision — creating opportunities for students, families, educators and communities to experience astronomy and technology in ways that are accessible, engaging and meaningful.

Looking Back at the Sky

The Great Conjunction eventually passed.

Jupiter and Saturn continued along their respective journeys around the Sun, gradually separating in our evening sky.

But for us, something had started.

We had discovered that even when circumstances restrict our ability to gather, curiosity cannot be quarantined.

A telescope can be moved.

A camera can extend its reach.

A livestream can cross boundaries.

And a simple explanation in someone’s own language can turn a distant point of light into a moment of discovery.

The Great Conjunction of 2020 was therefore not just an astronomical event in CSTERC’s story.

It was one of the evenings when we began discovering how we wanted to share science with the world.

And sometimes, the beginning of something significant doesn’t happen in a laboratory, a university or a large observatory.

Sometimes, it happens on an apartment terrace — with a telescope pointed at the sky, a camera connected to a laptop, and two planets meeting after centuries.
