Spitzer spies potential newborn planet
Posted: Fri, May 28, 2004, 10:35 AM ET (1435 GMT) Images from the Spitzer Space Telescope have turned up evidence of what may be a newborn planet forming around a young star. Images of the star CoKu Tau 4m only about one million years old, revealed a gap in the star's protoplanetary disk. That gap could be created by a planet forming in the disk and clearing out the material in and near its orbit. The studies are part of a survey of over 300 young stars in a stellar nursery called RCW 49, 13,700 light-years away; astronomers believe that all the stars there have protoplanetary disks of some kind. Other observations by Spitzer of nearby stars found what astronomers called the "raw ingredients" for life water, carbon dioxide, and methane in the icy dust particles in the disk.
