Subrahmanyan Chandrasekhar was an Indian-American astrophysicist who made significant contributions to the field of astrophysics, including his work on the theory of black holes and the Chandrasekhar limit.

The Giant Metrewave Radio Telescope (GMRT) is the largest radio telescope in the world, located in Khodad, India. It consists of 30 fully steerable parabolic radio telescopes, each with a diameter of 45 meters.

Aryabhata was an Indian astronomer and mathematician who lived in the 5th century CE. He is known for his work on the heliocentric model of the solar system, which placed the Sun at the center of the system and the Earth and other planets revolving around it.

Aryabhata was the first Indian satellite to be launched into space. It was launched on April 19, 1975, from the Satish Dhawan Space Centre in Sriharikota, India.

The Indian Space Research Organisation (ISRO) is the national space agency of India. It is responsible for the country's space program, including the development and launch of satellites, rockets, and spacecraft.

Rakesh Sharma was the first Indian astronaut to travel into space. He flew aboard the Soviet spacecraft Soyuz T-11 in 1984, becoming the first Indian to travel into space.

Bhaskara II was an Indian astronomer and mathematician who lived in the 12th century CE. He is known for his work on the theory of planetary motion and his development of the elliptical orbit model, which was later refined by Johannes Kepler.

Chandrayaan-1 was the Indian lunar mission that successfully placed a spacecraft into lunar orbit in 2008. The mission was launched on October 22, 2008, and the spacecraft entered lunar orbit on November 8, 2008.

Srinivasa Ramanujan was an Indian mathematician who lived in the early 20th century. He is known for his work on the theory of numbers and his development of the modular arithmetic system, which has applications in number theory, cryptography, and computer science.

AstroSat is the Indian space telescope that is being developed to study the universe in infrared light. It is scheduled to be launched in 2023 and will be used to study a wide range of astronomical objects, including stars, galaxies, and quasars.

Albert Einstein was a German-born physicist who lived in the early 20th century. He is known for his work on the theory of relativity and his development of the general theory of relativity, which revolutionized our understanding of gravity and the universe.

Mangalyaan was the Indian mission to Mars that successfully placed a spacecraft into Martian orbit in 2014. The mission was launched on November 5, 2013, and the spacecraft entered Martian orbit on September 24, 2014.

Karl Schwarzschild was a German mathematician and physicist who lived in the early 20th century. He is known for his work on the theory of black holes and his development of the Schwarzschild metric, which describes the geometry of spacetime around a black hole.

Gaganyaan is the Indian human spaceflight program that aims to send Indian astronauts into space. The program is scheduled to launch its first crewed mission in 2023, which will carry three Indian astronauts to the International Space Station.

Alan Guth is an American physicist who is known for his work on the theory of cosmic inflation and his development of the inflationary universe model. The inflationary universe model is a cosmological model that explains the rapid expansion of the universe in the early stages of its history.
