The Crab Nebula Introduction The Crab Nebula is a beautiful cloud of gas and dust easily visible with a telescope in the constellation Taurus the Bull (it is fairly close on the sky to the Pleiades asterism we studied earlier, in fact). These transits and occultations can be used to analyse both the nebula and the object passing in front of it, by observing how radiation from the nebula is altered by the transiting body. As the red giant expells its materials during its death process, some of the material gets attracted by the gravity of the white dwarf star. "How can we calculate the width of distant deep space objects?
