What is the Milky Way? The Milky Way is the band seen in the sky at night that has puzzled people for centuries. Today, we know that it shines because of the light of millions of stars: The Milky Way is a galaxy. There are many other galaxies in space-and many of them have very fanciful names, such as ' The Mice ', ' Cigar Galaxy ',or ' Antenna Galaxy '. Although we know about the Milky Way , there are still many mysteries and unanswered questions that baffle the astronomers, for example, the existence of 'dark matter'.

How far away are the stars from us?

How far away are the stars from us? Most of the stars are billions of  kilometres away form us. Billion is the number is nine zeros. However, astronomers specify distances in space in a different unit called, light years, as doing calculations with too many zeros is a problem. A light year is the distance covered by light in one year. The speed of light is 300,000 km/s. If we count the number of seconds in a year(60*60*24*365), and multiply it with the speed of light, we get the distance covered by light in one year: 9460 billion km. Proxima Centauri, the star nearest to the sun, is 4.2 light years away from the Earth.
