Neutron Stars: The Most Extreme Objects

It is a collapsed star so dense that electrons and protons do not exist separately, but are fused to form neutrons. It acts like an enormous magnet. Of course, a neutron star! We are talking about the mostr extreme objects in the universe

The term neutron star as generally used today refers to a star with a mass M on the order of 1.5 solar masses and a radius of about 12 km, with a density of about 5 to 10 times the nuclear equilibrium density of neutrons and protons found in laboratory nuclei, which makes it one of the densest forms of matter in the observable universe.
However, radio astronomers, jokingly, dubbed the source “LGM”, which stands for Little green men.
Soon, three similar sources were discovered in separated directions in the sky. This was clearly the start of something new, this was surely an important discovery that had to be further explored.
By today, more than 2500 such sources have been discovered; they are now called pulsars, short for “pulsating radio sources.”
In fact, the pulsar was just in the region of the supernova remnant. 
They could've been elusive corpses of massive stars!
Another thing to explain was: how made up a pulsar?
When the high-energy charged particles from the neutron star pulsar hit the slower-moving material from the supernova, they energize this material and cause it to “glow” at many different wavelengths—just what we observe from the Crab Nebula. 
The pulsar beams are a power source that “light up” the nebula long after the initial explosion of the star that made it.
Who “pays the bills” for all the energy we see coming out of a remnant like the Crab Nebula?
We would like to end this video by recalling a beautiful thing that happens when two neutron stars merge. 
A neutron star merger is a type of stellar collision. It occurs in a fashion similar to the rare brand of type Ia supernovae resulting from merging white dwarfs.
When two neutron stars orbit each other closely, they spiral inward as time passes due to gravitational radiation. When the two neutron stars meet, their merger leads to the formation of either a more massive neutron star, or a black hole (depending on the mass of the remnant).

The first such observation, which took place in August of 2017, made history for being the first time that both gravitational waves and light were detected from the same cosmic event.

Not going to lie, if I had superpowers, I would so fly to the closest one and just observe it and study it. Neutron Stars are so mystical.

Neutron star: I am the most extreme object in the universe.
Black hole: Aahhh, you are so cute.

Great video! Neutron stars are amazing!

[joshadams]

Strong video. One correction: Type 1a is pronounced “type one ay”, not “type eye ay”.

A special type of neutron star are my favorites. They are fast spinning and therefor they have a enormous magnetic field. So they are called Magnetars... A name I use on the internet.

Thanks for another awesome video!
I have a sort of impossible thought experiment. Mathematically speaking, what would happen if by some incredible power a spinning neutron star were instantly stopped - i.e., down to 0 rotations per second? Would it just explode?

I thought 1 teaspoon was a hundred million tons. I have heard this figure for 40 years.

[papaowl]

There beautiful. I want one ok please.

Sorry that I'm late but, shout out to my fellow space nerds!🖖👽

"The most extreme objects"?!? Well, I'd better strap in for some lnsanely Curious context.😍
