Clues

  • A group of stars in a recognizable patter that appear to be next to each otherin space (13)
  • a group of stars that are physically near each other in space, created by the collapse of the same gas cloud (7, 7)
  • A normal star that is undergoing fusion of hydrogen into helium. Our sun is a typical main sequence star. (3, 8, 4)
  • A star of variable luminosity. The luminosity increases sharply and falls off gently with a well-defined period. The period is related to the absolute luminosity of the star and so can be used to estimate distance to the star. (7, 8)
  • Galaxies close to each other and affecting each other gravitationally, behaving as one unit (8, 2, 8)
  • Gases and dust grains filling the space in between stars. The density of interstellar mass is very low . there is about one atom of gas for every cubic centimeter of space (12, 6)
  • If a red giant is very large, the end result of the explosion throwing off mass will be a star even smaller than a white dwarf and very dense. This star consists almost entirely of neutrons. (7, 4)
  • The ejected envelope of a red giant star (9, 6)
  • The remnant of a white dwarf after it has cooled down. It has a very low luminosity. (5, 5)
  • Two stars orbiting a common centre (6, 4)
