Nova Herculis 1991, shown in this PSPC image, is a fast, high inclination, long period nova which contains a massive white dwarf and is part of an eclipsing binary system. Novae occur as part of the evolution of a close binary system in which the stars have different masses, i.e. a main sequence star and a white dwarf. Mass is accreted onto the white dwarf which eventually ignites runaway thermonuclear reactions which blow off the outer layers of the star. ...

... It is generally accepted that the mechanism, widely known as the Antikythera mechanism, was made in Rhodes at the height of the Roman Republic, as the island was known as the source of interesting mechanical automata. You can tell just by looking at it that the device is part of a larger object, and it is also obvious that there are geared wheels and other rotational elements within it. The device undoubtedly is an early computer and could be seen as the first planetarium. ...

By studying how their light changes and other properties of these systems, astronomers can measure the distances to eclipsing binaries accurately. A long series of observations of these objects has now led to the most accurate determination so far of the distance to the Large Magellanic Cloud тАФ a crucial step in the determination of distances across the universe. ...
