SUMMARY: Astronomers working with the Subaru telescope have found a massive proto-star with a protoplanetary disk surrounding it. The star contains approximately 7 times the mass of the Sun, and astronomers weren't sure if such large stars would gather protoplanetary disks in the same way that less massive stars form them, such as our Sun. One theory, that massive stars are formed by collisions and mergers with smaller stars has lost ground because of this discovery.

Excellent news!
The planetary disc may be the source of some of the 'cool chemistry' products we find in our own system's presolar materials...
