Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific classification?Highly magnetized, rapidly rotating neutron star
2. What is the formation mechanism?Core collapse of massive stars followed by supernova explosion
3. How does a pulsar spin so fast?When a massive star explodes, the core collapses and keeps its angular momentum, so the tiny neutron star spins hundreds of times each second.
4. Why does a pulsar look like a lighthouse?The magnetic field is tilted, so the beams of radio waves sweep across space; when one beam points at Earth we see a bright flash that repeats over and over.

Neutron Star: A compact stellar remnant composed almost entirely of neutrons, formed from the collapsed core of a massive star.
Supernova: A transient astronomical event that occurs during the last evolutionary stages of a massive star, resulting in a catastrophic explosion.
Magnetosphere: The region surrounding a celestial body where its magnetic field is dominant.
General Relativity: Einstein's theory of gravitation, which describes gravity not as a force but as a curvature of spacetime caused by mass and energy.
