Luminous, gaseous planetary nebulae expand quickly and die young, when considered in astronomical years. When compact and symmetric, they can appear planet-like through a small telescope. <\/p>\n

University of Â鶹´«Ã½<\/span> at Mānoa Institute for Astronomy<\/a> Astronomer Roberto Méndez<\/strong> describes the evolution of understanding and unanswered questions about planetary nebulae in the latest issue of the IfA<\/abbr> newsletter Nā Kilo Hōkū<\/em><\/a>.<\/p>\n

Scientists believe the ionized gas becomes visible as red giant stars transform into white dwarfs, he writes.<\/p>\n
