Largest Star Records Demolished

Posted July 21, 2010 11:45 AM

From Geeks are Sexy:

R136a1 may sound like a lame attempt to create a more secure webmail password, but it's actually the biggest star ever discovered. The British astronomers who found it said this week that though it's currently 265 times larger than our Sun, it may well have been as much as 320 times larger when it was first born. That's twice the size of any star previously found.

Baloney. This one is much larger:

Canis Majoris Facts
VY Canis Majoris is the largest star known to man. It is a red Hypergiant, located in the Milky way and measuring between 1800 to 2100 solar radii. One Radius is equal to the current radius of the Sun and it is approximately 432,450 miles (695,500 kilometers). VY Canis Majoris is so large that if our Sun were replaced by it, its surface would extend to (or maybe even pass) the orbit of Saturn. In Earth terms it would take 70 000 000 000 000 000 (70 quadrillion) Earths to fill up the VY Canis Majoris.

VY Canis Majoris is the largest star known to man.

Its life span must/will be very short, if not already expired, just that the light of its death didn't arrive here yet.

speaking of which, I had marked this Keep it in perspective because it was cool, by a ex-member case491.....remember him.

While VY Canis Majoris is huge in terms of it's volume, it is in fact a red super-giant with a mass of (it is thought) between 15 and 25 solar masses. The monster discovered by these fellows is a type O super-giant more than ten times that. Thus while it may be smaller in terms of occupied volume, it is much denser, and correspondingly much, much hotter.

I thought of that. When someone says bigger or larger (as the CR4 news anchor did), I think of volume. Now, if you say massive, that means just what it says. Going to the GAS article, I see that they got it right.

A "huge" black hole waiting to happen.

Your reply prompted much internet delving (now that I'm home)! Thanks!
