Origin of Universe
The universe was created as a result of a huge cosmic explosion that occurred 15 billion years ago which resulted in expanding a tiny, dense cloud of hot gases spreading mass and energy.
Big Bang Theory
This planet is named after the Roman God of Messenger because of its speedy movement around the Sun.
Mercury
This is the study of the origin of the universe and life of it as a whole.
Cosmology
He is considered the father of Indian Space Program. He is known for his pioneering efforts to set up ISRO and use space technology for the benefit of society.
Vikram Sarabhai
This satellite was launched using SLV-III, India’s first indigenously developed rocket on 18 July 1980 marking India’s journey towards self-reliance in space technology.
Rohini Satellite
The most famous book ever written by Stephen Hawking explains in easy language how and why the universe originated.
A Brief History of Time
These are made up of pieces of ice and rocks, which were once parts of comets, asteroids, and other space debris, and now form this distinctive pattern due to strong gravitational pull.
Saturn's Rings
This is the study of large distances within the universe using mathematical techniques like trigonometry, parallax, etc.
Astrometry
He is best known for his work in nuclear physics. He is known for setting up the Tata Institute of Fundamental Research, which became the cradle for many nuclear and space missions.
Homi J Bhabha
This is an ISRO-commissioned project, launched in 1983 (still active) that revolutionized telecommunications and broadcasting in India. It also has multipurpose uses like weather forecasting, meteorology, search operations, etc.
INSAT (Indian National Satellite System)
This theory suggests that during the formation of the universe, the energy density was dominated by vacuum energy which decayed to produce all the matter and radiation present today.
Inflation Theory
This is a region in the solar system with irregularly shaped asteroids speedily orbiting the sun and acting as a separation between the inner and outer solar system.
Asteroid Belt
This is the study of planets in the solar system and those orbiting stars other than the sun.
Planetology
He is remembered to have run one of the most successful tenures as Director of ISRO, particularly his work on the SLV project and his role in making India’s Defense stronger with numerous missiles.
APJ Abdul Kalam
This is India’s first interplanetary mission and it set up a record to achieve the feat in the first attempt. The mission aimed to study the surface and atmosphere of the planet to meet life-support expectations.
Mangalyaan/Mars Orbital Mission
This theory was proposed in 1949 and suggests that, although the universe is expanding, new matter is continuously formed to keep the matter density constant.
Steady State Theory
This is the largest moon in the solar system and a part of Jupiter’s atmosphere.
Ganymede
This is the study of celestial objects that emit electromagnetic radiation - the ones that are detected are mainly under 300 GHz.
Radio Astronomy
He was the first astronomer to deduce that Earth is round, not flat. He also explained the occurrence of day/night as the rotation of Earth on its axis.
Aryabhatta
This venture by ISRO consists of a number of Indian satellites used for a particular feature. Launched in 2012, this series of satellites are used for providing high-resolution pictures that help in national security and disaster management.
RISAT (Radar Imaging Satellite System)
This theory suggests that the universe is expanding and contracting alternatively to maintain material balance, controlled by the direction of gravitational pull.
Pulsating Theory
This planet was discovered mathematically before being observed physically by studying the anomaly caused by Uranus’s orbit shape and revolution time.
Neptune
This study mainly involves explaining different parameters of the universe using calculations, numbers, and statistics.
Mathematical Astronomy
He is famous for his theoretical work on stellar evolution and for setting up a formula that describes the maximum mass of a stable white star that helps to calculate its life.
S Chandrasekhar
This is the first mission of ISRO to one of our neighboring planets planned for 2026. The mission aims to investigate the possibility of life due to the recent discovery of phosphine in their atmosphere.
