      WHEN GALAXIES COLLIDE
      -------------------------
      A new image taken by the Chandra X-Ray Observatory has provided
      one of the best views of two galaxies similar to our own Milky
      Way in the midst of a collision. All galaxies, including our
      own, have gone through this kind of merger in the past, so this
      image helps astronomers understand how the Universe came to look
      like it does today. The galaxies began their slow collision
      10-million years ago and have already created regions of intense
      star formation and may eventually create a supermassive black
      hole.

      ESA PLANS ANOTHER LOOK AT THE MOON
      -------------------------
      The European Space Agency is working on a new spacecraft that
      will visit the Moon and map its surface in great detail. The
      SMART-1, due for launch in 2002 will arrive at the Moon and
      begin a detailed analysis of the surface from different angles,
      in regular light, infrared and X-ray and then produce a
      three-dimensional map. Smart-1 will visit the dark southern pole
      of the Moon for the first time and help investigate areas which
      have never been touched by the Sun.

      NASA APPROVES SHUTTLEWORTH'S VISIT
      -------------------------
      NASA has given its blessing for millionaire space tourist Mark
      Shuttleworth to visit the International Space Station. The
      previous paying visitor, Dennis Tito, was permitted into the
      station, but required constant supervision. Shuttleworth will
      lift off Thursday on board a Russian Soyuz rocket from the
      Baikonur cosmodrome in Kazakhstan and dock with the station
      Saturday.

      HUBBLE HELPS WITH NEW MEASUREMENT FOR UNIVERSE'S AGE
      -------------------------
      Thanks to the Hubble Space Telescope, astronomers are using
      ancient stars in the Milky Way to come up with an independent
      estimate about the age of the Universe. In the past, astronomers
      have calculated this age using its rate of expansion, and pegged
      it between 13-14 billion years old. Under this new method, the
      astronomers targeted ancient white dwarf stars which cool down
      at a very predictable rate. These stars were formed near the
      beginning of the Universe, and the astronomers were able to
      estimate that they are between 12-13 billion years old. Close
      enough.
