• Black holes attract everything near it, including
  light, and anything that goes in, sometimes never

• Black holes are caused by gravitational collapse.

• Gravitational collapse is the final stage in the
  life history of certain stars.

• A comet is a astronomical body of small mass
  moving about the sun in a more or less elongated
  orbit.

• There are 120 comets known as the Jupiter family
  because they have aphelia that are located close
  to the orbit of Jupiter.

• Comets are generally classified according to the
  size and shape of their orbits, as either
  long-period or short-period objects.

HUBBLES WORLD
12

• The Hubble Space Telescope was built from 1978 to
  1990 at the cost of 1.5 billion.

• In 1990, Hubble was transported into orbit by
  Space Shuttle Discovery in shuttle mission STS-31.

• The Hubble Space Telescope receives annual
  servicing missions from NASA.
