The nearby star Fomalhaut A hosts the most famous planetary
system outside our own Solar System, containing both an exoplanet and a
spectacular ring of comets. Today, an international team of astronomers
announced a new discovery with the Herschel Space Observatory that has made
this system even more intriguing; the least massive star of the three in the
Fomalhaut system, Fomalhaut C, has now been found to host its own comet belt.
The researchers published their results today in a letter to the journal Monthly
Notices of the Royal Astronomical Society.
