The Scale Of Space

The scale of space

The universe is so fast that it can not appreciate its size without making leaps of scale. in this series of pictures, each Stage represents a microscopic pic of the image to its right. when dealing with the vast distance in Space, kilometres are'nt big enough, instead, astronomers use the speed of light as a yardstick. Light year so fast it can travel around the earth 7.5  time in one second, light years is the distance light travels in a year nearly 10 trillion km( 6 trillion mile)

Stellar neighborhood

The nearest star to the sun is  proxima centauri,  which is just over 4 light year away. there are around 2000 staff within 50 light years of the Sun. this make up  our  stellar  neighborhood, which is tiny fraction of Milky Way galaxy

Milky Way galaxy

 The milky way is a vast cloud of 200 billion stars. its shape reassembles pair Of tired eggs held back to  back, with a central bulge  surrounded by a flat disc. it measures 1,00,000  light year across the disc and two thousand light years around the bulge

Local group of  Galaxy

 

The Milky Way  just one of perhaps  galaxies in the  observable universe. Galaxy exist in groups called clusters, held Together by Gravity. The milky way is a part of cluster known as local group which is above 10 trillion light years wide.

Supercluster

 

clusters of galaxies exist in 7 larger groupings called superclusters. live in the virgo  supercluster in the known universe. between these are immense empty areas called cosmic  voids.

Universe 

superclusters are thought to form a vast web of filaments riddled With enormous voids Containing no galaxies. The true size of the universe is mystery, and only a fraction of it is visible to us. the universe may even be infinite.
