I know each one of you have looked at the stars many times, but when you stare at them , what do you think about? That we may not be alone? The vastness of it all?
There's a lot to wonder about space and stars. The fact is that we ask plenty of questions and have infinite thoughts about space,but we don't know all the answers. We know it's wide and wonderful, but we're not really sure how wide (or how wonderful for that matter).
Some of the things we do know, however, are absolutely mind blowing. For that, I've collected some of the most striking facts about space, so when you look up at the stars the next time, you can be ever more wowed by what you're looking at , and by the mysteries in God creations.
1. Neutron stars can spin at a rate of 600 rotations per second

1. Neutron stars can spin at a rate of 600 rotations per second
One of the potential evolutionary endpoints of high mass stars are the neutron stars. They are formed in a supernova star core-collapse blast, and then spin extremely rapidly as a result of their physics. Neutron stars after they are born will rotate up to 60 times per second. This rate can rise to more than 600 times per second under special circumstances.
2. Space is completely silent
Sound waves need a medium to pass through it. Since the vacuum of space has no atmosphere, the domain between stars will always be eerily silent.That said, atmospheric and air pressure worlds cause sound to fly, so there's plenty of noise on Earth as well as other planets .
3. If two pieces of the same type of metal touch in space, they will bond and be permanently stuck together
This spectacular effect is known as cold welding. This occurs because the atoms of the individual metal pieces have no way of knowing that they are different metal pieces, so that the lumps bind together.This would not happen on Earth, since the pieces are divided by air and water. The effect has a great deal of consequences for the design of a spacecraft and the future of metal production in vacuum.
4. One day on Venus is longer than one year on Earth
Venus has an extremely slow rotation of the axis which takes about 243 Earth days to complete one complete cycle. Funny enough, it takes even less time for Venus to complete one revolution around the sun in Earth days—226 to be precise.
