Hubble Adds a New Dimension to Nebula
News story originally written on January 7, 1999
Scientists used the Hubble Space Telescope to look at the Ring Nebula
(also known as M57). The nebula
gets its name from its shape--it looks like a ring. The HST pictures show
that the nebula is actually shaped like a cylinder.
The nebula formed from gas escaping from a dying star. The gas first
formed a band around the middle of the star, which slowed down other gas
that was escaping. The gas then filled in the open areas above and below
the middle band. That's how the nebula got its cylinder shape.
