Hubble images don't show actual planets, but rather
the edge-on disks of gas and dust that eventually
condense to form planets around young stars. Although
astronomers have discovered about 30 possible
extrasolar planets over the past few years, they
have never gotten such detailed pictures of the
planet-forming environments around newborn stars.
Located 450 light-years away in the constellation
Taurus, the stars all sport dusty disks that appear
as dark bands. The disks are believed to be eight
to 16 times the diameter of Neptune's orbit. In
addition, the images show that raw material is
still falling into these disks and driving jets
of gas from the forming stars.
