Latest Bipolar nebula Stories
Planetary nebulae occur in the final stages of a star's life when its outer layers begin to stretch out into the surrounding space. These nebulae can create beautiful objects in the night sky, with some stretching out into an hourglass or butterfly shape.
The Hubble Space Telescope has "caught" the Boomerang Nebula in these new images taken with the Advanced Camera for Surveys. This reflecting cloud of dust and gas has two nearly symmetric lobes (or cones) of matter that are being ejected from a central star.

Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...
