The countdown continues as the Galileo spacecraft continues its journey with a visit to the planet Jupiter. Galileo's atmospheric probe will be released into Jupiter's atmosphere on December 7th, giving us information about the structure and composition of the largest planet in the solar system.

The Exploratorium will cover the action "live" in the McBean Theater from 2:30-5:30PM on Thursday December 7th. The events we hope to cover will be....

  • 2:45 PM Pacific: Closest approach to Jupiter (perijove)
  • 2:59 PM Pacific: Probe transmissions begin (60-75 minutes)
  • 4:14 PM Pacific: Probe transmissions end
  • 5:19 PM Pacific: Engine firing; Jupiter orbital insertion (49 minutes)
Astronomy experts both at the Exploratorium and San Jose's Tech Museum will answer questions. A live Internet video conference between the two sites will allow visitors and scientists to exchange questions and answers while participants watch the action from NASA's blue room

The location of "Pegasus 51" pinpointed with Voyager II software. Pegasus can be seen high in the south in the early evening hours. Image courtesy of Carina Software.


Astronomers from two independent teams announced they have confirmed for the first time the existence of a planet outside of our solar system. A team of Swiss astronomers announced that they found a planet orbiting a star named "Pegasus 51." This observation was confirmed by Geoffrey Marcy and Paul Butler astronomers from San Francisco State University.

Pegasus 51 is 44 light years from earth and is similar in size and temperature to the sun. The planet can't be seen because the light of its parent star but Marcy and Butler were able to detect a slight wobble in the star's movement. The team made their observations at Lick Observatory in the mountains above San Jose, California.
