Khagol Vishwa (KV) is an organization for amateur astronomers working in Pune and Pimpri - Chinchwad Area, India. It was established on 17th Nov. 1999, under Society Registration Act, 1960. Science popularization, observation and analysis of astronomical events, public star gazing programs are some of the main activities of this organization.[1]


In 1998, the Leonid meteor shower was expected with outburst. Some enthusiastic students from Pune and Pimpri Chinchwad area came together to observe that event scientifically. After observing that glorious event, all of them got inspired to do something different in Amateur Astronomy. They decided to form an official group under which they could come together; discuss on various topics in Astronomy, observe various events in the Sky and contribute to present amateur astronomical world. A group of 4 - 6 amateur astronomers in 1999 is now a well-known science exploring organization ‘Khagol Vishwa’. Khagol Vishwa is now working for a national Goal ‘Vision 2020’.


There are four main sections

Observation section[edit]


Planetary observations are helpful to study changes in the surfaces and study of satellites of planets like Jupiter, Saturn and Saturn Rings, Lunar surface and as well as transits and oppositions of Planets. These observations are visual and photographic.

Variable stars[edit]

Visual observations of variable stars and plotting the light curves. These observations are reporting to the organizations- AAVSO. Khagol Vishwa has formed a special Variable Star Section (VSS) for detailed study in this field.


All types of eclipses, occultation of stars by planets and asteroids, lunar occultation, transits, timing these events, Photography and CCD observations for study of particular Astronomical body.

Deep sky[edit]

This section works for study of faint objects in the night sky. Observations of NGC and Messier objects, comet hunting, photography of deep sky through telescopes.

Science popularization section[edit]

This section works to popularize basic sciences and astronomy in society. Some of the activities under this section are

Khagol Prasar Abhiyaan[edit]

Translated as Astronomy Popularization Movement, under this, khagol vishwa conducts lectures on astronomy in schools, colleges as well as open public lectures. There are also Star Gazing Programs once or twice a month.

Pimpri-Chinchwad science congress[edit]

A district level science congress is organised every alternate year. The aim of this event is to spread the awareness about fundamental sciences in high school students and to discuss local problems and issues and to encourage students to develop the science and technology to solve them.

Research and development section[edit]

The aim of formation of this section is to create atmosphere of research and development (R&D) in India on amateur level. It will be helpful to encourage more and more students to do something, to find something for our society and Nation even if he/she is not with science background and working in different types of fields.

Some main projects under progress are ham radio networking for tele-education and communication under emergency, Mini weather stations in all main villages for knowing local environment, helpful for students and farmers, Creating electricity from bio gas, amateur mobile observatory for deep sky study and study of Near Earth Objects (NEO), Analyzing observations taken by all observers, publishing papers, making research projects.

Instrumentation section[edit]

No research can be done without proper instruments. Khagol Vishwa tries to buy advance instruments necessary for its activities and to make them available to students and members. Some of these instruments are made by members themselves under Research and Development section.

Lonar conservation project[edit]

Khagol Vishwa is one of the few organisations all over India who are working to create social awareness about the Lonar lake and also campaign against its environmental degradation [2] . The organization has been studying the site for past 8 years and published the first report 2 years ago. The different aspects of Lonar crater has been studied by their members like, geology and structure, ecology - flaura, fauna, agriculture, zoology, sociological, water level problem, pollution of Lonar Lake.
