A pulsar (pulsating star) is a neutron star that emits very intense jets of electromagnetic radiation in the range of radio waves, X-rays or gamma rays, at short and periodic intervals due to its intense magnetic field that induces this emission.
One of its main charateristics is its rapidly rotation (spin) when this star is young. So, as the star spins, beams of radio radiation from it sweep through space. If one of these beams points toward the Earth, we observe a <u>pulse</u>.
This is possible when the magnetic pole of the star "points" to the Earth and then stops pointing a thousandth of a second later due to the fast rotation of the star, appearing again when the same pole returns to point towards Earth.
How does an atom change if all of its electrons are removed? The atom becomes positively charged. The Venn diagram compares protons with electrons. ... Protons have an electrical charge, but neutrons have no charge.
