A drogen fuel relatively quickly, and have shorter lives and certainly spectacular deaths. 4 solar mass), the beginning- of the end is when it expands to a hundred times its size and becomes a red giant. One of the most famous examples of red giants is Betelgeuse, seen as Orion's shoulder (top left from northern latitudes). It has a diameter equivalent to 800 Suns and has a mass twenty times that of our star. Sunlike stars expand to become red giants when all the hydrogen has been used up in their core: as a result, the core shrinks and heats up.

Since then, Right: The galaxy NGC 4319 with a quasar arrowed. The quasar is apparently no farther away than 46 the galaxy. further quasars have been observed, including one which is travelling at 96% the velocity of light in the most distant reaches of the known universe. Though they still present many theoretical problems, astronomers bethey can be explained as the lieve of active galaxies containing massive black holes which can literally feed on the stars and material at its centre. This will produce enough energy to explain the great luminosities observed at radio wavelengths.

37 Pulsars During a supernova explosion, most of the swollen star's material is blown into space. All that is left is a core so utterly small that the remaining material is crushed even more densely than that inside a white dwarf. 5 miles) across. Even the protons and electrons (positively and negatively charged particles) within them become fused particles without together to electrical form charge so dense (neutrons). The material is that even a pinhead of it would weigh around a million tonnes!
