2. created when giant stars die in supernovas and their cores collapse
3. electromagnetic wave of frequency
7. This is a space telescope that looks for gamma ray burst
9. a fermion that interacts only via the weak interaction and gravity
12. This is an explosion of energy from tangling of magnetic field lines near sunspots
13. The compression of neutrons in the contracting core
16. the small, dense region consisting of protons and neutrons at the center of an atom
18. a pulsar type neutron star located in the constellation Vulpecula
19. she helped build a large radio telescope and discovered pulsars
20. The time it takes for a planet to spin once

1. highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles.
4. fast moving electrons create a pressure _________ which is capable of supporting a star!
5. Two bodies which are close enough that their gravitational attraction causes them to orbit each other
6. penetrating form of high-energy electromagnetic radiation
8. This is a space where gravity is so powerful that no particles or electromagnetic radiation can escape or get out of it
10. how the magnetic force is distributed in the space around and within something magnetic
11. a circular motion which acts along the radius and is directed away from the centre of the circle
14. A eruption of high energy radiation from the sun’s surface
15. a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
17. a type of neutron star believed to have an extremely powerful magnetic field
