Carl Sagan was an American astronomer, who was also a leading figure in other branches of science like cosmology, astrophysics and astrobiology. Sagan is most famous for popularizing science among the general people through his books. His most important and perhaps most significant work is the research that he carried out on extraterrestrial life and that is something that remains one of the top priorities of space research organisations even today. Sagan was a prolific researcher who produced hundreds of research papers throughout a stellar career that spanned over a period of more than three decades. In addition to that, he had also written several popular science based books among which ‘Pale Blue Dot’ and ‘The Dragons of Eden’ are the most famous ones. Sagan was also the co-writer of the hugely popular show ‘Cosmos: A Personal Voyage’ that went on to win several awards. As one would ex-pect, Sagan has also left behind a rich haul of quotes that would appeal to curious minds of all ages, irrespective of their aptitude for the sciences and here are some of the choices ones.

Somewhere, something incredible is waiting to be known.

Carl Sagan

Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.

Carl Sagan

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.

Carl Sagan

Science is not only compatible with spirituality; it is a profound source of spirituality.

Carl Sagan

One glance at a book and you hear the voice of another person, perhaps someone dead for 1,000 years. To read is to voyage through time.

If you wish to make an apple pie from scratch, you must first invent the universe.

The universe is a pretty big place. If it's just us, seems like an awful waste of space.

Carl Sagan

If we long to believe that the stars rise and set for us, that we are the reason there is a Universe, does science do us a disservice in deflating our conceits?

Not explaining science seems to me perverse. When you're in love, you want to tell the world.

Carl Sagan

We make our purpose.

Carl Sagan

If we are merely matter intricately assembled, is this really demeaning? If there's nothing here but atoms, does that make us less or does that make matter more?
