What is a Neutron Star?

What is a Neutron Star?

Physics, science concepts
Simply put, a neutron star is the leftover core of a dead star. It gets its name 'neutron' from the fact that the protons and electrons in each atom in the core combine to form neutrons. This also produces some of the densest matter discovered so far. Typical neutron stars have a mass of up to three solar masses (around 5,967,000,000,000,000,000,000,000,000 tn), which is crammed into a sphere with a radius of approximately ten kilometres (our sun's radius measures 695,700 km !). Therefore the material can weigh upto 6 billion tonnes a teaspoon. At this point most feel that, "okay, it's super dense, is that all?". No, its not. Our Earth obtained most of th heavy elements such as gold, silver, platinum when two neutron stars collide. This occurs when two neighbouring stars die together

4 Quick Scientific Facts that Will Blow Your mind

Did you know there is enough DNA in an average person's body to stretch from the sun to Pluto and back 17 times? The human genome, the genetic code in each human cell, contains 23 DNA molecules each containing from 500 thousand to 2.5 million nucleotide pairs. DNA molecules of this size are 1.7 to 8.5 cm long when uncoiled, or about 5 cm on average. There are about 37 trillion cells in the human body and if you’d uncoil all of the DNA encased in each cell and put them end to end, then these would sum to a total length of 2×1014 meters or enough for 17 Pluto roundtrips (1.2×1013 meters/Pluto roundtrip).  It can take a photon 40,000 years to travel from the core of the sun to its surface, but only 8 minutes to travel the rest of the way to Earth A photon travels, on average, a par
