Neutron Stars Can Spin At A Rate Of 600 Rotations Per Second

5 Facts About Space

Neutron stars are one of the evolutionary end-points of high mass stars. They're born in a core-collapse supernova star explosion and subsequently rotate extremely rapidly as a consequence of their physics. Neutron stars can rotate up to 60 times per second after born. Under special circumstances, this rate can increase to more than 600 times per second.

If Two Pieces Of The Same Type Of Metal Touch In Space, They Will Bond And Be Permanently Stuck Together

5 Facts About Space

This amazing effect is called cold welding. It happens because the atoms of the individual pieces of metal have no way of knowing that they are different pieces of metal, so the lumps join together. This wouldn't happen on earth because there is air and water separating the pieces. The effect has a lot of implication for spacecraft construction and the future of metal-based construction in vacuums.

On Venus A Day Is Longer Than A Year

5 Facts About Space

This is tricky one but a year on Venus (that is the length of time it takes to complete one whole orbit around the Sun) is 224.7 Earth days. However it takes 243 Earth days to rotate on its axis just once.
