Brilliant Massive Stars
The image below is just breathtaking. I found it at the Astronomy Picture of the Day site and just gaped at it for a few moments. Pictures like this are what draws us all to astronomy — if for nothing else than the sheer loveliness of such distant, alien visions. This was actually released a couple of years ago as a part of a story about looking for what we thought might have been the heaviest (most massive) star in the Milky Way Galaxy. When astronomers first studied this region, they speculated that there was a single star here that could be as much as 200 solar masses, which would make it the most massive known.
It turns out that what they thought was a single massive star was, in fact, three stars with about 100 solar masses divided between them. If you’re interested, they’re the central bright stars above the cloud in this image. Even three stars having a hundred solar masses is … well… massive. These stars will become insanely bright and stupendous supernovae when they die. And, below them is a huge stellar nursery, cranking out more hot, young stars for future astronomers to study!
