PRESS RELEASE NO.: STScI-PR04-32
A NEW TWIST ON AN OLD NEBULA
Looks can be deceiving, especially when it comes to celestial objects
like galaxies and nebulas. These objects are so far away that
astronomers cannot see their three-dimensional structure. The Helix
Nebula, for example, resembles a doughnut in colorful images. Earlier
images of this complex object -- the gaseous envelope ejected by a
dying, sun-like star -- did not allow astronomers to precisely interpret
its structure. One possible interpretation was that the Helix's form
resembled a snake-like coil. Now, a team of astronomers using
observations from several observatories, including NASA's Hubble Space
Telescope, has established that the Helix's structure is even more
perplexing. Their evidence suggests that the Helix consists of two
gaseous disks nearly perpendicular to each other.
