The father of modern astronomy is called - Copernicus (Poland)
The sun is the center of the solar system and the earth revolves around it, said - Copernicus
The earth is the center of the universe and the sun revolves around it, said - Ptolemy
The law of motion of planets was propounded by - Johannes Kepler (Germany)
The universe is continuously expanding, said - Edwin Hubble in 1920
Development of the solar system - 4.5 billion years ago
The fundamental particle of the universe is - Higgs Boson
Another name for Higgs boson is - God particle
Where is CERN located where an attempt was made to create Higgs boson in 2010 by the Large Hadron Collider (LHC) machine - Geneva
Age of the universe -13 billion years
Diameter of the universe -10° light years
An exploding star in the universe is called - New star or Supernova
Supernova - Explosion state of a dying star
The distance covered by light in 1 year is called - Light year
The largest unit of astronomical distance - Parsec
1 parsec is equal to -3.26 light years
Light year is the unit of - distance
1 light year is equal to -9.46×1012 km or 9.46×1015 m.
Galaxy is - a group of gases, clouds, dust particles and billions of stars
The name of our galaxy is - Milky Way
The galaxy in which our solar system or sun is located is called- Milky Way
The shape of the galaxy is- spiral
The name of the nearest galaxy to the galaxy is- Devyani (Andromeda)
The galaxy was first seen and Jupiter was discovered by- Galileo
Nebula is- a huge cloud of dust and gases in space
Nebula visible to naked eyes- Orion
Pulsars are- fast rotating neutron stars
The lighthouse of the universe is called- Pulsar
Source of energy in stars- nuclear fusion
Main components of stars - Hydrogen and Helium
Earth's nearest star - Sun
Sun's nearest star - Proxima Centauri
Brightest star - Sirius (Dog Star)
The colour of a star indicates its temperature
Star twinkling - Refraction of light
Black hole theory was given by - S. Chandrasekhar
S. Chandrasekhar got Nobel Prize - 1983
The limit beyond which stars suffer internal death is called - Chandrasekhar Limit
Chandrasekhar Limit is - 1.44 Sun mass

Largest constellation - Centaurus (94 stars)
Smallest constellation - Hydra (68 stars)
The smallest constellation is Hydra (68 stars)
The Pole Star is a part of the Small Big Dipper
The Pole Star helps in determining the direction
The Pole Star indicates the north direction
Comet - A body made of dust, ice and gas
The comet (tail) that appears once in 76 years - Halley (last seen in 1986)
Halley's comet will be visible again - in 2062
Order of planets according to size (in descending order) - Jupiter, Saturn, Arun, Neptune, Earth, Venus, Mars and Mercury
Order of planets according to distance from the Sun (in ascending order) - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Arun and Neptune
The central part of the Sun is - the core
Temperature of the Sun's surface -6000°C
The outermost layer of the Sun - Corona
Corona emits -X-rays
The luminous surface of the Sun is called - Photosphere
The upper part of the photosphere which is not luminous - Chromosphere
The main components of the Sun are - Hydrogen (71%), Helium (26.5%) Other elements (2.5%)
Source of the Sun's energy - Nuclear fusion
Size of the Sun - 109 times larger than the Earth
The average distance between the Sun and the Earth is - 149.598 × 105 or 149.6 million km.
Solar eclipse occurs - when the Moon comes between the Sun and the Earth
