Scientists have found evidence of two mega solar systems - giant stars enveloped by what appear to be huge disks of planet-forming dust, they said Wednesday.
The appearance of cloudy disks around stars are believed to represent current or future planetary systems.
Our sun is surrounded by the Kuiper Belt, a disk containing dust, comets and other bodies.
Astronomers say the latest findings through NASA's Spitzer Space Telescope were surprising because such massive stars are thought to be inhospitable to the formation of planets.
The new stars are believed to be 30 to 70 times more massive than the sun. Because of the stars' size, scientists say the surrounding debris disks are larger versions of the Kuiper Belt and probably contain about 10 times more mass.
