Welcome to the Bangalore Astronomical Society. We are a group of volunteers working for the promotion of astronomy as a hobby as well as a science in and around Bangalore, India.

Join the discussion!

We do not have formal memberships. Our primary channels of communication are our very active Telegram/Discord/Matrix and Google Groups.

The Chat Groups are the place where most of the astronomy discussion happens. You can join the group from Telegram, Discord or Matrix, and participate in the same conversations thanks to bridging. Since most of our members join via Telegram, the best experience is on Telegram. These groups, which have over 500 members, are amongst the most active online communities in India for amateur astronomy. Feel free to post your questions about the universe, astronomy, telescopes, star-gazing, observing, astrophotography etc. in either group.

Watch out for event announcements pinned on the Telegram group and posted to the Google group.

2020: Astronomy Webinars!

A lot of us are ending up without much to do at home because of the COVID-19 pandemic. To keep the spirit of astronomy alive in these difficult times, BAS is organizing a series of online webinars with a regular cadence, almost every Sunday! Talks are recorded and uploaded on our YouTube channel.

Visit our YouTube channel! »

Some video recordings are featured below.

If you are interested in attending these sessions live, check our Google Group for notifications and details on how to join! They are free and no registration is necessary.

Call for volunteers

BAS needs your help to grow! We are always looking for volunteers to help with various activities.

If you wish to volunteer, please indicate your interest on the Telegram group and an admin will help you out.
