Dr. J.N. Goswami is a renowned Indian scientist who has made significant contributions to the study of cometary composition. He is known for his work on the identification of various molecules and elements in comets, including carbon monoxide, hydrogen cyanide, and formaldehyde.

The Indian Institute of Astrophysics (IIA) is a leading institution in India that conducts research on cometary structure. Its scientists have made significant contributions to understanding the morphology, dust distribution, and nucleus properties of comets.

Spectroscopy is the primary technique employed by Indian scientists to study the composition of comets. By analyzing the light emitted or reflected by comets, spectroscopists can identify the presence of various molecules and elements.

The Vainu Bappu Observatory (VBO) is a major astronomical observatory in India that has been used to observe comets and study their structure. Its telescopes have been employed to obtain images and spectroscopic data of comets, providing valuable insights into their physical properties.

Astrosat is an Indian spacecraft that was launched in 2015 to study various astronomical objects, including comets. It carries a suite of instruments that allow scientists to observe comets in multiple wavelengths, providing valuable information about their composition and structure.

Dr. J.N. Goswami led the team that discovered the presence of water vapor in Comet Hale-Bopp in 1997. This discovery was a significant milestone in cometary research, as it provided strong evidence for the presence of water ice in comets.

The Comet Interceptor is an Indian cometary mission that is currently under development. It aims to intercept and study a pristine comet that has not been significantly altered by solar radiation. The mission is expected to provide valuable insights into the composition and structure of comets.

Dr. A.S. Dhillon is a renowned Indian scientist who has made significant contributions to the study of dust distribution in comets. His work has helped to understand the structure and dynamics of cometary comae and tails.

COSIMA (COmetary Secondary Ion Mass Analyzer) is an Indian instrument that was part of the Rosetta mission to Comet 67P/Churyumov-Gerasimenko. COSIMA analyzed the composition of cometary dust particles and provided valuable insights into the chemical makeup of the comet.
