... GSAOI Home . ... Science . ... 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. ...

... Bad Astronomy . ... Mad Science . ... if hubble was pointed at earth, what could it resolve? is it too bright? ... This type of image is called a ``flat field'', because you want the field of view to look as flat as possible. In space there aren't any flat fields you can use, but we do have one right here: the Earth. ... It takes a lot of sophisticated computer processing to turn this into a real flat field for Hubble to use, but luckily there are a lot of smart people working on the problem. ...
