Thanks Greg, that is interesting.
What fascinates me the most is......
"The system, known as LH54-425, is located in the Large Magellanic Cloud, a satellite galaxy of our Milky Way. The binary consists of two O-stars, the most massive and luminous types of stars in the Universe. ...... With a combined mass of about 100 suns, the system is one the most extreme binaries known."
......the word "known". It is surely most probable that out there, in galaxies farther away that the humble LMC, binary systems exist which put this one to shame. And this one is amazing enough!
Ain't the universe an incredible place!
