It is about 5 times more massive - so it is going through the planetary nebula phase and then turn into a white dwarf - the same last stage for our Sun. If it was more than 10 times as massive, then we would have expected this star to explode a supernova before leaving a neutron star core. <br /><br />As far as the size is concerned, the structure is around 2 light years across. That is about half the distance from our Sun to the Centauri system. Sun's planetary nebula may not end up being that big - but half that size is not so crazy. But we don't know what Sun's planetary nebula is going to look like. It largely depends on how mass is ejected from the star - and so far, astronomers don't have a unified theory in this regard. In fact, Hubble has captured a phenomenal variety of planetary nebula - irrespective of their initial masses. I guess, humans will have to watch it from a colony in another star system :)Salman Hameedhttps://www.blogger.com/profile/04327330113822656571noreply@blogger.comtag:blogger.com,1999:blog-38085367.post-71791174979182317242009-10-17T17:04:51.332-04:002009-10-17T17:04:51.332-04:00Hmmm...to create a phenomenon of such a scale, I t...Hmmm...to create a phenomenon of such a scale, I think the central star has to be much much bigger and hotter than our Sun.Muhammad Akbar Hussainhttp://astronomer.zoomshare.comnoreply@blogger.comtag:blogger.com,1999:blog-38085367.post-41675635781271828792009-10-17T17:03:57.023-04:002009-10-17T17:03:57.023-04:00Hmmm...to create a phenomenon of such a scale, I t...Hmmm...to create a phenomenon of such a scale, I think the central star has to be much much bigger and hotter than our Sun.Muhammad Akbar Hussainhttp://astronoer.zoomshare.comnoreply@blogger.com
