Govind Swarup is an eminent Indian radio astronomer who played a significant role in the establishment of the Giant Metrewave Radio Telescope (GMRT) in India. He is also known for his contributions to SETI and has been involved in several international collaborations in this field.

Astrosat is India's first dedicated astronomy satellite, launched in 2013. One of its primary objectives is to search for exoplanets, which are planets orbiting stars other than the Sun. Astrosat has made significant contributions to the study of exoplanets and has helped identify several potential candidates for habitable worlds.

Jayant Narlikar is a renowned Indian astrophysicist and cosmologist who has made significant contributions to the study of galaxies and the early universe. He is known for his work on the Hoyle-Narlikar theory of gravity and his contributions to the understanding of black holes and the Big Bang.

The Giant Metrewave Radio Telescope (GMRT) is a large radio telescope located near Pune, Maharashtra, India. It is an array of 30 fully steerable parabolic radio telescopes, each with a diameter of 45 meters. The GMRT is used for observations in the low-frequency range (150-1420 MHz) and has made significant contributions to the study of pulsars, galaxies, and other astronomical objects.

Subrahmanyan Chandrasekhar was an Indian-American astrophysicist who made significant contributions to the study of stars and supernovae. He is known for his work on the Chandrasekhar limit, which determines the maximum mass of a white dwarf star, and his contributions to the understanding of the evolution of stars and the formation of black holes.

Mangalyaan, also known as the Mars Orbiter Mission, is India's first interplanetary mission. It was launched in 2014 with the primary objective of studying the Martian atmosphere, surface features, and searching for evidence of past or present life on Mars. Mangalyaan successfully entered Mars' orbit in September 2014 and has been providing valuable data about the Red Planet since then.

Tulika Pandey is an Indian astrophysicist who is known for her work on the formation and evolution of planetary systems and her contributions to the understanding of exoplanets. She has made significant contributions to the study of protoplanetary disks, the regions around young stars where planets are formed, and has helped identify several new exoplanets.

Chandrayaan-1 was India's first lunar mission, launched in 2008. Its primary objective was to study the lunar surface, mineralogy, and chemical composition, and to search for evidence of water or other resources on the Moon. Chandrayaan-1 successfully entered lunar orbit in November 2008 and provided valuable data about the Moon's surface and composition.

Jayant Narlikar is a renowned Indian astrophysicist and cosmologist who has made significant contributions to the study of the origin and evolution of the universe. He is known for his work on the Hoyle-Narlikar theory of gravity, his contributions to the understanding of black holes, and his work on the early universe and cosmology.

Aditya-L1 is India's first dedicated solar mission, launched in 2017. Its primary objective is to study the Sun's corona, chromosphere, and photosphere, and to understand the Sun's impact on Earth's climate and space weather. Aditya-L1 is positioned at the Lagrange point 1 (L1), which is about 1.5 million kilometers from Earth in the direction of the Sun.

Jayant Narlikar is a renowned Indian astrophysicist and cosmologist who has made significant contributions to the study of the formation and evolution of galaxies. He is known for his work on the Hoyle-Narlikar theory of gravity, his contributions to the understanding of dark matter and dark energy, and his work on the early universe and cosmology.

Mars Orbiter Mission 2, also known as Mangalyaan 2, is India's second interplanetary mission, launched in 2019. Its primary objective is to study the Martian surface, atmosphere, and mineralogy, and to search for evidence of past or present life on Mars. Mars Orbiter Mission 2 is expected to reach Mars' orbit in September 2023.

Tulika Pandey is an Indian astrophysicist who is known for her work on the formation and evolution of stars and her contributions to the understanding of stellar evolution and nucleosynthesis. She has made significant contributions to the study of protostellar disks, the regions around young stars where stars are formed, and has helped identify several new stars and stellar systems.

Aditya-L1 is India's first dedicated solar mission, launched in 2022. Its primary objective is to study the Sun's corona, chromosphere, and photosphere, and to understand the Sun's impact on Earth's climate and space weather. Aditya-L1 is positioned at the Lagrange point 1 (L1), which is about 1.5 million kilometers from Earth in the direction of the Sun.
