Tales of the Universe

    

print version

There are huge numbers of other galaxies apart from our own. Along with the empty space and dust clouds in between, they all together form what we call the Universe. The size of the Universe is still unknown and we don't know if it will expand forever or if it will collapse far in the future. Neither do we know how or why the Universe started!

But measurements from ground telescopes and from satellites in space try to solve these unanswered questions.
