While disks of dust are known to exist at ranges comparable to our Kuiper Belt, until now scientists have never found an analogue to the belt of minor planets between Mars and Jupiter. On Monday, two researchers from the University of California, Los Angeles released their findings here at the 198th meeting of the American Astronomical Society.

The three satellites, known collectively as the Three Corner Sat mission, will fly in a close formation and will be capable of dealing with unexpected problems in space, including solar storms and equipment failures.

Young stars are usually created in stellar nurseries, which harbour many type O and B stars that emit massive amounts of blowtorch-like radiation. Planets forming around any star in this kind of a nursery are blown apart early in their formation. Only stars that form in an area shielded from radiation have a chance for planets.
