Nuclear Fusion is
What is the process of combining hydrogen nuclei into helium nuclei?
Spiral Galaxies are
What are galaxies with long curving arms that follow the direction of rotation?
A black hole is
What is a region in space that cannot be seen with the naked eye and has an extremely powerful gravitational field in which nothing not even light can escape?
A red supergiant is

A planetary nebula is
What is the remains of a sun like star at the end of its life that leaves behind the expanding shell of gas and a white dwarf which is all that remains of the original star?

A prominence is
What is a loop of plasma that follows the suns magnetic field lines?
Dark Matter is
What is matter that emits no light at any wavelength?
An Irregular Galaxy is
What is a galaxy with a lot of new star formation and an irregular shape?
A pulsar is
What is a rapidly spinning neutron star with a powerful magnetic field that can spin thousands of times per second which causes two beams of pure radiation to be emitted from the stars poles?
