As seen with the naked eye, the comet will appear as a faint, misty patch of light, but the head of the comet, known as the "coma", and its tail should be easily visible with binoculars. To get your bearings, note the three bright stars that make up the "summer triangle", namely Vega, Deneb and Altair, and the small constellation, Sagitta. Last Revised: 06/02/1997 .

Despite vast increase in our understanding of the evolutionary nature of planetary nebulae (PNe) during the last three decades, a central question remains: where is the missing mass? Theoretical evolutionary tracks predict that all stars with masses in the range 1.4-8 M Sun should become PNe. ... Clearly, much of the mass of the planetary nebula shell must remain un-ionized, and much of it may be in molecular form. ... The Magellanic Cloud PNe are ideal for this. ...
