Hubble Space Telescope Images Source:  Hubble Space Telescope "Two Stars Going Haywire" The NASA/ESA Hubble Space Telescope has just captured new images of two nearby stars putting on a spectacular fireworks display in outer space.  They are two planetary nebulae named the Butterfly nebula and NGC 7027.  Astronomers say they are highly unusual, among the dustiest planetary nebulae ever discovered and contain unusually large amounts of gas. Nuclear Fusion Stars are engines of nuclear fusion.  They live peaceful lives for billions of years.  But near the end of their lives the fireworks start with erupting jets of hot gas from them exploding into the universe.  Astronomers say the complexity and rapid changes in the jets of gas shooting off these two stars is unprecedented.  The new Hubble images demonstrate that the two stars are splitting themselves apart in a very short timeframe.
