20 Extraordinary And Inspiring Facts About The Universe

Posted on

The universe is so vast it’s extremely difficult to know the full extent of its complexities. Humans can only scratch at the surface of its immensity, but whenever we do we pick up remarkable information, and images, which are awe inspiring and baffling in equal measure. What we do know has been made readily available to the public thanks to the leading space exploratation organisations, so here are 20 of the most intriguing facts for your reading pleasure.

1. When you look into the night sky, you are looking back in time


The stars we see in the night sky are very far away from us, so far the star light we see has taken a long time to travel across space to reach our eyes. This means whenever we look out into the night and gaze at stars we are actually experiencing how they looked in the past. For example, the bright star Vega is relatively close to us at 25 light-years away, so the light we see left the star 25 years ago; while Betelgeuse (pictured) in the constellation of Orion is 640 light-years away, so the light left the star around 1370, during the time of the Hundred Years’ War between England and France. Other stars we see are further away still, so we are seeing them much deeper in their past.

2. The Hubble telescope allows us to look back billions of years into the past


The Hubble Telescope enables us to look towards very distant objects in the universe. Thanks to this remarkable piece of engineering NASA has been able to create some incredible images, one of which is the Hubble Ultra Deep Field. Created using images from the telescope from 2003 and 2004, the incredible picture displays a tiny patch of the sky in immense detail; it contains 10,000 objects, most of them young galaxies, and acts as a portal back in time. In one picture we are transported 13 billion years into the past, just 400 to 800 million years after the Big Bang, which is early in terms of the universe’s history.
