Neutron Stars, Densest Objects in the Universe

When a star about 1- 3 times the size of our Sun reaches the end of its life, it has the mass large enough that it explodes in a super nova, blowing off the lighter elements and the atoms of heavier elements remain behind. (The above picture is from spacedaily.com)
The remaining mass of heavy atoms is under such huge gravitational force that the protons and electrons "melt" or fuse together. The protons are positive and the electrons are negative, so when they combine, they create neutrally charged particles, neutrons.
Accumulation of a huge amount of neutrons can actually stabilize and prevent further collapse under gravity, assuming its mass was not greater than about 3 solar masses. (If a star has more than 3 solar masses, it has sufficient mass to go beyond a neutron star and collapses to form a black hole. When a Star is not quite large enough to create a black hole, (less than 3 solar masses) the Neutron Star is born. 

(The image above is from www.universetoday.com).Most neutron stars are only about 10-12 miles in diameter however, it is estimated that neutron stars are so dense that a teaspoon of neutron star matter, can weigh 100,000,000 tons! (yes, that is not a mistake. It is 100 Million Tons).
In addition, neutron stars spin incredibly fast because of their immense mass and conservation of angular momentum. Some Neutron Stars actually send out radio waves! We measure them on Earth and the signal can be turned on if the star is tilted torward Earth or off iff the Star is tilted away from Earth....very cool. 
Can you believe the Universe contains such amazing things?
It is the Universe,as usual, that never dissappoints.
