If you feel this video sucks and you can make a better one: go for it and post a link. Go to 50% if you wanna skip the intro and hear The Star. Ok, so here's the deal, it's pretty simple: As a big fan of cosmology and astronomy (I was making rudimentary DIY telescopes when I hit 10) I've found a _real_ video of a pulsar. And I've found an audio of it. But I wasn't able to find "a video _and_ audio (It's stupid I know). So I decided to fix it using Ancient Forgotten Shaolin Skill of "Video Editing": this is the first video of a pulsar with _audio_ in it. To give you an instant impression: The Star we're talking about here is not even visible on these images, that's a tiny dot of 12 miles in size in the center of those 2 rings. Those rings and jets and all of that majestic shininess - that's just an effects of that 20km ball of neutron matter. We cannot see the _real_ star from that distance. But the energy it emits is just shocking to any human being. 1. Neutron stars are getting produced as a result of Supernova bursts. That's when massive "regular star" of 10-29 Solar masses got burned it's typical "Hydrogen-Iron" cycle and then collapsing into itself under it's own mass, releasing HUGE amounts of energy and dropping external layers of matter in an enormous explosion. Energy emitted in that explosion can exceed the energy of a whole galaxy for a short time (hours / days). 2. Neutron star consists of a _very-very-very-very-very-very_ dense matter. Human brain cannot imagine how dense is it. Approx. density is 10^25(10 with 22 zeros) metric tons per cubic centimeter. There are no molecules or atoms inside - just neutrons and quarks, smallest subatomic particles, foundation of our Universe packed so dense, that they exist in superfluid/superconducting state. And since that matter is a superconductor and neutron stars are spinning very fast, they're producing enormous magnetic fields that are 1000 billion times stronger than Earth's field (So called Magnetars). 3. Typical neutron star diameter is just 10-20km. But it's mass is 10-29 solar masses. Yes, all that stuff is 'packed' into a spinning sphere of a tiny size. Yet producing enormous radiation and magnetic fields that we can see thru the millions and billions of light years. There are no "neutron mountrains" in there, Neutron Stars are smooth as baby's head. (20km in diameter, "mountains" are human hair tall). 4. Neutron stars are emitting energy primarily thru the tiny particles named "Neutrinos" that are able to escape the Star's overheated core and enormous gravity field since they're almost not reacting with the normal matter. So, energy comes not 'outside' from the surface of a Neutron Star as we might think, but _toward the center_ of the star and getting emitted as neutrinos outside from the core of a star. Fun fact: All the elements around you heavier than Iron were produced in a huge Supernova burst. Yes, all the gold you wear, all the Plumbum or Uranium around are products of a huge stellar explosion. Without Supernovas we wouldn't have any gold. Without them we wouldn't basically exist. --- "There's was video without sound and audio without video in all those yours internets. I think we deserve to have a video with sound and short info in one place at the end of 2016 ;)" Source: 8 photos taken by Chandra at June-Sept 2010 Name: Vela Pulsar, PSR B0833-45 Type: Neutron star / Binary Distance: 1000 light years Size: ~19.2 km / 12 miles Mass: ~1-2 solar masses approx 1 full turn: 89.33 milliseconds, 11.192/second Jets speed: 70% of light speed When: Supernova exploded ~10000 years ago Area in frame: 1.4 by 1.0 light years Mass of 1 tbsp of it's matter: ~mass of Everest mountain http://www.parkes.atnf.csiro.au/people/sar049/eternal_life/supernova/pulsars.html http://chandra.harvard.edu/photo/2013/vela/ http://lanl.arxiv.org/abs/1211.0347 http://iopscience.iop.org/article/10.1088/0004-637X/763/2/72/pdf http://www.wikiwand.com/en/Vela_Pulsar All information is taken from open sources.
