Facts About The Universe We Never Paid Attention To
Have you looked up in the sky and wondered how Earth might look from up there? Although the universe is so vast we can never know everything about it, but thanks to NASA we now have access to know more about the infinite and breathtaking universe we belong to. Take a look at these awe-inspiring facts we should definitely think about more than our petty issues. When we look up at the night sky, we are looking back in time
The star light we see in the night sky has taken a long time to travel across the space to reach our eyes, that means, whenever we gaze at stars we are actually experiencing how they looked in the past. For example, the bright star Vega is 25 light years away from Earth, so the light we see is actually 25 years old. When we see stars, we are literally seeing the past. The Hubble Telescope
It is possible to look back billions of years into the past through The Hubble Telescope. This incredible engineered piece of NASA has made amazing images of the sky in immense details, which comprises of around 10,000 objects. One of the pictures transported us 13 million years into the past, nearly 400-800 million years after Big Bang, which is pretty much early for the universe. A Cloud Full Of Alcohol
In the center of the Milky Way, 26,000 light years away from Earth, there’s a cloud 463,000,000,000 kilometers in diameter, named Sagittarius B, full of molecular gas and dust and it contains 10 billion liters of alcohol. The vinyl alcohol in the cloud is far from the universe, but it gives out clues on life produced on Earth.
Biggest Mountain In The Universe
Standing 26 kilometers high and 600 kilometers across, Olympus Mons on Mars is the tallest mountain on any of the planets of the Solar System. It is almost three times the height of Mount Everest.
Neutron star spins at 70,000 kilometers per second that is the fastest spinning object in the universe and is incredibly dense. A spoonful of matter collected from the center of the Neutron Star is estimated to weigh up to one billion tons.
The Voyager Program
Artist’s concept of Voyager by NASA
The Pale Blue Dot
In 1977, the Voyager Program launched two spacecraft to explore planets and moons of the outer Solar System over several decades. In 2013, the Voyager 1 became the first furthest man-made object away from the Earth. And has also captured Earth from the furthest distance ever, which is 6 billion kilometers away. The picture is named as ‘The Pale Blue Dot’ as Earth doesn’t seem any matter of interest from that distance but it is the home for those astronauts.
Nothing is as complex as the human brain
With a hundred billion of neurons and quadrillions of connections, a human brain is supposed to be the most complex discovery of science. We can form language, culture, consciousness, learn and understand, transfer emotions and feelings into ideas but we still can’t compete with the super organic computers. Amused!
We are all just dust, Stardust!
The nitrogen in our DNA, calcium in our teeth, iron in our blood were made in the interiors of collapsing stars. NASA has studied stardust immensely and confirms that every element found on Earth is created in the burning core of a star, we are all made of star stuff.
We are always moving
Our Milky Way Galaxy is rotating at 225 kilometers per second, so in one minute we travel approximately 20,000 kilometers or more than 12,000 miles. Hence, nothing on Earth can be stationary, even at rest, we are moving fast enough. So next time someone asks where have you been, remember this!
We are 4 billion years’ old
Earth has been around for about 4.54 billion years but life on this planet has been around for a short time. The variety of life has evolved from single-celled organisms to giant mammals and of course, ‘us- the homo sapiens’. And apparently, one million Earth can fit inside the Sun.
Let’s take a moment to thank the Universe.
