What is a Neutron Star?

Here's just some of what we already know about neutron stars. An upcoming NASA mission will further investigate these unusual objects from the International Space Station. The Neutron star Interior Composition Explorer mission, or NICER, will study the extraordinary environments — strong gravity, ultra-dense matter, and the most powerful magnetic fields in the universe — embodied by neutron stars. NICER is a two-in-one mission. The embedded Station Explorer for X-ray Timing and Navigation Technology, or SEXTANT, demonstration will use NICER data to validate, for the first time in space, pulsar-based navigation.

i love all these scientists and astronomers in the comments, who knew there were so many geniuses who just happen to know the secrets of the universe!!

[WhitefoxSpace]

I love the music and general creative direction behind this video, well done.

[jackssparrow]

its been over a whole year since someone has left a comment lol also well done this video was amazingly interesting!

Does a Neutron star always go through a supernova?

[VillegasCar]

very nice explanation, loved the cinematics

[fisicoolchannel]

u could put for download the videos proj, i am from brazil, and i woul translate what is on screen, if i have proj i could edit the text

Why do some stars become white dwarfs and some neutron stars?

[houaritahir]

OMG! What you said exists in Qur'an

[--Valek--]

a neutron star is a bunch of numbers written by someone who is good at math.

[SillySatire]

Another video ruined by unnecessary music.

That is ridicules 1 teaspoon does not weigh billions of tons that is bs

Neutron stars are made by the anti-christ *Hugh Neutron* from the anime "Jimmy Neutron b0i genius"

Computer graphic nonsense and a case against neutron stars.The following is hypothetical scenario based on known physics, which would explain the Improbability of neutron stars ; Neutron is made out of an electron and proton and neutrino, (neutrons are Known to be unstable due to Beta decay) they say Neutrinos escapes because of nuclear decay and low mass or close to Zero mass the neutrinos would be lost Or radiated out, it must be remembered that neutrino is part of the ingredients of a neutron . After losing a neutrino what would be left is a proton and a electron, which would constitute the ingredients of a hydrogen atom not a neutron, being that the protons Is heavier (1800 x) then the Electron it is quite possible that the interior will become a large Proton like object, but only if there is enough gravity, there for, it should be called a proton star and not a neutron star, . The core would be of pure hydrogen nuclei. Between these two scenarios the most plausible would be proton star, because it is based on known physics. Neutron star Scenario just doesn’t make sense ! The fact is that a neutron stars is actually Hypotheticals objects and the physics that is suppose to supports this is vague . The Pauli exclusion principle Is introduce because it helps explain the density packing, but there are other forces That will inhibit these high densities ever being achieved. So there is no credible explanations about how the Neutron star would be kept together. This hypothetical neutron star explantation is one dimensional thinking, which ignores other factors in physics. So don’t be fooled!

WHY IS THE SPEAKER BRITISH!!! THAT REALLY RUINED THE VIDEO.. PLEASE PLEASE PLEASE CHANGE IT TO AN AMERICAN ACCENT. WHY NASA DOES NOT HAVE AN AMERICAN IT IS AN AMAZING WORK BY NASA..

No such thing as a so called "Neutron star".
Most of the mainstream science dictating how the Universe works is wrong. Very wrong!
