Neutron stars are amongst the most powerful objects in our galaxy. They are so dense that they have a gravitational pull of such strength that if anything strays too close it is dragged on to the star with extreme force. Neutron stars seem to contain enough energy to produce these gamma ray bursts ... What was actually triggering them? Horizon: The Death Star 2001
Compared with ordinary stars, neutron stars are cosmic pebbles. They can be as small as ten miles across. Squeezing that huge amount of mass into such a tiny space produces an extremely dense object. One teaspoonful of neutron star material would weigh a billion tons ... The phenomenon of rapid spin first enabled astronomers to identify neutron stars. The Universe s1e10: Life and Death of a Star, History 2007
There are two types of neutron star: pulsars that spin rapidly and emit beeping radio pulses, and magnetars that spin more slowly and emit energy from magnetism. Magnetars which are much rarer than pulsars have the strongest known magnetic fields in the universe. The Universe s3e10: Strangest Things, History 2009
The pulsar/magnetar combination star is fairly young – less than nine hundred years old. So astronomers think neutron stars begin their lives as magnetars then settle down and become pulsars. ibid.
The super-dense core is now a neutron star. It’s around thirty kilometres across. And unbelievably heavy. How the Universe Works s1e4: Stars, Discovery 2010
But pulsars aren’t the strangest thing a supernova can leave behind. When stars thirty times bigger than our sun explode they produce a type of neutron star called a magnetar. Magnetars are even stranger than pulsars and generate powerful magnetic fields. How the Universe Works s1e5: Supernovas
Sometimes there’s a corpse. The type of corpse depends on the size of a star. Supernovas from stars more than eight times bigger than our sun leave behind a neutron star. And it’s one of the strangest objects in the universe. ibid.
A teaspoon of neutron star would weigh over ninety million tons. ibid.
Some neutron stars spin so fast they generate huge pulses of energy. Beams of radiation blasting out of the star’s north and south poles. This neutron star is called a pulsar. ibid.

Even after it’s gone supernova it would be a place best to avoid. Because after it dies what’s left is one of the most extreme objects in the universe – a neutron star. Trillions and trillions of tons of matter are compressed into a sphere that’s just tens of kilometers in diameter. Because the neutron star is so dense it generates an intense gravitational field. How the Universe Works s5e6: The Universe’s Deadliest
But what about two neutron stars colliding? Creating one of the strangest and most lethal particles in the universe … releasing a huge surge of energy that was emitted across space … It’s possible that neutron star collisions release something that is incredibly weird – a new theoretical particle called a Strangelet. ibid.
Neutron stars. Extreme gravity magnetic hot. A cosmic conundrum. How the Universe Works s7e1: Nightmares of Neutron Stars, Science 2019
Neutron stars have suddenly moved into the astronomical limelight. ibid.
It’s the first time astronomers have seen two neutron stars collide. ibid.
Never in my wildest dreams did I think we would ever find planets orbiting a neutron star, a supernova. Alex Filippenko, University of Berkeley
We think that supernovae produce a stupendous sum of neutrinos when the core collapses to a neutron star. Professor Stan Woosley
Some of the most violent stellar collisions occur between neutron stars. Neutron stars are remnants of older massive stars. Neutron stars rotate extremely rapidly. Some of them orbit each other in a binary system ... When they finally collide they release more energy than the sun would produce in billions of years. The impacts are too fast for telescopes to capture. Cosmic Collisions: Galaxies, Discovery 2009

We now have a brand-new wave of measuring the evolution of the universe: the Hubble Constant. ibid.
