AstroSat is a multi-wavelength space observatory launched by the Indian Space Research Organisation (ISRO) in 2017. One of its primary objectives is to study dark matter and other astrophysical phenomena.

Jayant Narlikar is an Indian astrophysicist and cosmologist who has made significant contributions to the study of dark matter and the Milky Way Galaxy. He is known for his work on the Hoyle-Narlikar theory of gravity and the steady-state cosmology.

The Milky Way Galaxy is estimated to have a mass of approximately 10^12 solar masses. This includes the mass of the stars, gas, dust, and dark matter within the galaxy.

Sagittarius A* is the supermassive black hole at the center of the Milky Way Galaxy. It is located about 26,000 light-years from Earth and has a mass of approximately 4.3 million solar masses.

The dark matter halo of the Milky Way Galaxy is thought to be composed primarily of weakly interacting massive particles (WIMPs). WIMPs are hypothetical particles that are massive but do not interact strongly with ordinary matter.

Hanle Observatory is an astronomical observatory located in Ladakh, India. It is operated by the Indian Institute of Astrophysics and is known for its high-altitude location and clear skies, making it ideal for astronomical observations.

T. Padmanabhan is an Indian theoretical physicist and cosmologist who has made significant contributions to the study of the formation and evolution of galaxies, including the Milky Way Galaxy. He is known for his work on black hole physics, cosmology, and gravity.

Aditya-L1 is an Indian space mission that aims to study the Sun's corona. It is scheduled to be launched in 2023 and will be placed in a halo orbit around the Sun's L1 Lagrange point.

P.C. Vaidya is an Indian astrophysicist and cosmologist who is known for his work on the cosmic microwave background radiation and its implications for the study of dark matter. He is also known for his work on black hole physics and general relativity.

NISAR is an Indian satellite that was launched in 2013 to study the Earth's atmosphere and ionosphere. It is a joint mission between ISRO and NASA and is designed to provide valuable data on the Earth's climate and space weather.

R.K. Kaul is an Indian astrophysicist and cosmologist who is known for his work on the origin and evolution of the universe, including the Milky Way Galaxy. He is also known for his work on black hole physics and general relativity.

Aryabhatta Research Institute of Observational Sciences (ARIES) is an astronomical observatory located in Nainital, India. It is operated by the Aryabhatta Research Institute of Observational Sciences (ARIES) and is known for its high-altitude location and clear skies, making it ideal for astronomical observations.

D.J. Saikia is an Indian astrophysicist and astronomer who is known for his work on the structure and dynamics of galaxies, including the Milky Way Galaxy. He is also known for his work on radio astronomy and cosmology.

Mangalyaan is an Indian space mission that aims to study the Martian atmosphere and surface. It was launched in 2013 and successfully entered Mars' orbit in 2014, making India the first Asian country to reach Mars.

Harinder Singh is an Indian astrophysicist and astronomer who is known for his work on the evolution of stars and galaxies, including the Milky Way Galaxy. He is also known for his work on black hole physics and cosmology.
