"Most Massive stars ever"

Oprah, Rosie O' Donnell, Roseanne... oh wait, the topic is Astronomy, nevermind.


 ;D

regarding the link though, In a strange twist, I actually find it entirely un-amazing... even dissappointing, in some ways. I haven't been heavily into Astronomy since I started working with computers (so I don't follow astronomical news like this) and the books I have are pretty ancient (let's just say they are the same age as a College book titled "applied Structured basic"... that is, late 70's or so)

Anyway, the book has a "artists rendering" of the size comparison between the sun and betelguese:



the picture is actually a two-page spread covering the lower half of both pages, but I sort of cut it out for size, which is actually the opposite of what I usually do with two-page spreads, which is to enlarge them.


Alright, so we have that... and now today they find the "most massive stars" and we get this picture:




One of those has got to be wrong! I want to blame the fact that the Betelgeuse one was based on incorrect data (it being way older and all), but there is actually a thermal  graphing of the star's surface, so I have no idea what to think here.



I was trying to dereference Null Pointers before it was cool.

This is interesting. When I read it I found it hard to believe that the brightest star is 22 million times brighter than the Sun.

The second image is correct. This took me ages to get it sorted on my site and there is still a rogue image around that needs deleting... still looking for it.
