The Universe

• The galaxy named Abell 1835 IR1916is the most distant object in the Universe, according to the European Southern Observatory, in Chile. It is about 13,230 million light years away from us.

• A galaxy that contains a highly luminous core and emits intense radiation is known a Active Galaxy. The closest one of this type to use is Centaurus a, just eleven million light years away.

• The Orion Nebula is the brightest nebula in the sky. Located in the ‘sword’ of the constellation of Orion, it is easily visible to the naked eyes.

• The star named LBV 1806-20, located 45,000 light years away from us, is the most luminous star. It is five million to 40 million times brighter than the sun.

• The hottest place in the solar system is the centre of the Sun. The estimated temperature of the core of the Sun is 15,000,000 degree Celsius. About Five million tones of hydrogen are fused into helium here, every second.

• The first stars die, and the elements from them form new stars.

• Clouds of hydrogen and helium form galaxies and stars.

• Electrons combine with protons and neutrons to form atoms, mostly hydrogen and helium.

• Still too hot to form into atoms. Charged electrons and protons prevent light from shining.

• The cosmos start to cool. Small particles turn into bigger particles, like protons and neutrons.

• Just after the inflation, the cosmos became a hot soup of small particles like quarks, electrons, etc.

• At a tiny fraction of a second the cosmos inflates from the size of an atom to that of a cherry.
