ScienceDaily: NASA's Spitzer Uncovers Hints Of Mega Solar Systems

NASA's Spitzer Space Telescope has identified two huge "hypergiant" stars circled by monstrous disks of what might be planet-forming dust. The findings surprised astronomers because stars as big as these were thought to be inhospitable to planets. This illustration compares the size of a gargantuan star and its surrounding dusty disk (top) to that of our solar system.

"Our data suggest that the planet-forming process may be hardier than previously believed, occurring around even the most massive stars that nature produces."
