Do missing Jupiters mean massive comet belts?
London, UK (SPX) Nov 29, 2012
Using ESA's Herschel space observatory, astronomers have discovered vast belts of comets surrounding two nearby planetary systems known to host nothing larger than Earth-to-Neptune-mass worlds. The comet reservoirs could have delivered life-giving oceans to the innermost planets. The scientists publish their work in papers in Monthly Notices of the Royal Astronomical Society and Astronomy and Astrophysics. Last year, Herschel found that the dusty belt surrounding the nearby star Fomalhaut must be ... read more
