what would be a neat idea would be take a picture of crab nebula each month for 5 years and then put those photos in sequence and watch it expand , that would be awesome

so i heard rumors.
I heard the crab nebula sends out gamma rays

According to Spitzer Research Scientist Varoujan Gorgian: Yes, the Crab Nebula does emit Gamma Rays. Their source is the same as the source of most of the other emission from the Crab which is generated by particles that are accelerated by the pulsar at the center of the nebula and the interaction of those particles with the magnetic fields inside the nebula. This is called synchrotron radiation and this process can generate light from radio waves all the way out to Gamma Rays!

@JPLnews So have scientist have found use for the crab Nebula's Gamma Rays?
shadowburninggundam 2 years ago
The main use of the Gamma Rays is to help us understand what is going on in the Crab Nebula. Since Gamma Rays are very energetic wavelengths of light, they tell us that there are very energetic processes going on inside the nebula to generate that very energetic light. But besides helping increase our knowledge of the Crab, the amount of Gamma Rays reaching Earth is too little to do anything else with.

And the 'Pulsar' is an electrical phenomena, no exotic neutron stars nor crazy rotations of extraordinarily dense mass is needed to explain this phenomena.

At 2:25 you state that Spitzer shows 'the electrons in the Star's Magnetic field', that is a plasma,all the formations, even the stars themselves are plasma formations, a planet even has plasma dynamics. Unfortunately you are all blind in spite of your eyes and tools, the universe is electric, at every scale and every phase, the Crab Nebular is nothing more than a plasma formation with braids and filaments illustrating a plasma glow mode.

You're welcome! Working on December now. Orion nebula (one of my favorites!!)

haha hooker telescope...
why is it named like that?
Allexxx96 2 years ago
It's named after John D. Hooker who funded it.

John D Hooker funded the big mirror, so they named the telescope after him. He was a millionaire, in the hardware business and president of Western Union Oil Company. He was also a great friend of naturalist John Muir.

I truly enjoy these videos, keep posting! :D
I hope my 5" refractor will be able to see some details.. Being in the city is a pain, now that it's getting so cold at night this far north...
Ah well.. suffering is good for the soul... :)

Light pollution in the city won't help but a 5-inch refractor should show you the "smudge" from the city, except if your city is LA like mine. ;-)

By local time, do you mean by US or elsewhere? Because I really do want to see the meteor shower. :)
xyingweix 2 years ago
Yes, your own local time. So where ever your live, try looking up well after midnight! Between 2 a.m. and close to dawn are the best times to see meteors. There are 2 showers - 12th Taurids, 17th Leonids. that means in the nights before, during and after those dates you'll see meteors! (if it is not raining, that is)
