Q1. What are quasars?
Ans. Quasars are tiny star-like objects far away in space. We can only see them because they give out so much energy. Astronomers are still not sure what they exactly are!!!
Q2. What is a pulsar?
Ans. Is it a bike?? No, guys, actually pulsar is a spinning neutron star, left behind after a large supernova explosion. It is called a pulsar because of pulses, or flashes of energy it sends out as it spins.
Q3. What is a space station?
Ans. A space station is a large spacecraft which stays in orbit around earth. Scientists can live and work there for long periods of time. The Russian Mir Space Station was launched in 1986.
Q4. Can space make astronauts ill?
Ans. When astronauts stay in space for long periods for time, lack of exercise and weightlessness can affect them- bones lose calcium and muscles become weak. Without the protection of earth’s atmosphere, astronauts may be affected by harmful rays from the sun.
Q5. What is space?’
Ans. Space is the name we give to the region beyond our planet, Earth, which may stretch forever. Space and its content are called universe.

What the hell was before BIG BANG???
Returning to my quest for exploring the universe, I always wondered about its beginning. Many theories, a hundred of explanations, and a thousands of logics have been applied to this question and what comes out to be the most appealing one is BIG BANG theory. But was BIG BANG really the beginning??
If no, then what would have existed before it? A kind of "ZERO-matter world" or something like that~!! Sounds funny...but looking to the serious aspect of the topic I feel millions of questions striking to open my doors of perception in mind.
Since childhood, the night sky has always amazed me in a frolicsome sense. The silence which penetrates into my soul while sitting below the shady shines of the moon gives a big thrust to my inquisitiveness. Different kinds of stars, nebulae, planets, clusters, comets, asteroids, quasars, etc. studded in the sky are never-ending treasures for me. But how did it all began? Although BIG BANG Theory gives a vital support of answer for this question but still there are several strong contradictions opposing this theory. I have always tried to feel the need to expand my visions about such contrary objects. Still now, apart from my school fusses, I try to spend most of my time thinking about this….Yet I got no answer.
I’ll continue…Hope you all enjoyed reading.
