View Full Version : Discussion: Learning How Planets Form

2003-Oct-21, 07:32 PM
SUMMARY: Astronomers are hoping NASA's new Space Infrared Telescope Facility will answer more questions about how disks of gas and dust turn into a planetary system. The problem is that the disk seems to get obscured by material during the middle stages of its formation. SIRTF should be able to peer through the obscuring material to reveal this missing link of planetary formation. At some point in the system's evolution, mass is eaten up by the star, ejected into space or transformed into planets - SIRTF may help to solve this riddle.

How about a single planet? How was the Earth formed? What's your theory?
