A Real Surprise?

A Real Surprise?

Crab Nebula consists of a Pulsar present in the center.

A pulsar is a rotating neutron star(dense star made of neutrons) with a jet stream of gas and dust.

In the above image there is red line(pulsar), orange line(magnetic field),blue line(synchrotron emission).

Synchrotron emission is a electromagnetic radiation produced by charged particles(electrons) emitted in the presence of magnetic field, when the acceleration is perpendicular to the velocity (a, v).

Electrons are pushed outwards the pulsar because of the acclearation of the particles of pulsar.

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
