... STScI-PR98-15 HUBBLE REVEALS DETAILS OF A NEWLY BORN PLANETARY NEBULA Astronomers have caught a peek at a rare moment in the final stages of a star's life: a ballooning shroud of gas cast off by a dying star flicking on its stellar light bulb. NASA's Hubble Space Telescope has captured the unveiling of the Stingray nebula (Hen-1357), the youngest known planetary nebula. ... A fast wind - material propelled outward from the hot central star -- compresses the gas and pushes the gas bubble outward. ...
