Read the passage to answer question 16-20

The explosion of a star is an awesome event. The most violent of these cataclysms, which
produce supernovae, probably destroys a star completely. Within our galaxy of roughly
100 billion stars the last supernova was observed in 1604. Much smaller explosions,
however, occur quite frequently, giving rise to what astronomers call novae and dwarf
novae. On the order of 25 novae occur in our galaxy every year, but only two or three are
near enough to be observed. About 100 dwarf novae are known altogether. If the exploding
star is in a nearby part of the galaxy, it may create a “new star” that was not previously
visible to the naked eye. The last new star of this sort that could be observed clearly from
the Northern Hemisphere appeared in 1946. In these smaller explosions the star loses only
a minute fraction of its mass and survives to explode again. Astrophysicists are fairly well
satisfied that they can account for the explosions of supernovae. The novae and dwarf
novae have presented more of a puzzle. From recent investigations that have provided
important new information about these two classes of exploding star, the picture that
emerges is quite astonishing. It appears that every dwarf nova – and perhaps every nova –
is a member of a pair of stars. The two stars are so close together that they revolve around
a point that lies barely outside the surface of the larger star. As a result the period of
rotation is usually only a few hours, and their velocities range upward to within a twohundredth of the speed of light.
