What are the implications of a star systems missing a massive gas giant such as our Solar Systems' Jupiter --it could imply conditions of massive bombardment from comets and asteeoids that would prevent the development of advanced life.
The artist's impression below of the debris disc and planets around the star known as Gliese 581, superimposed on Herschel PACS images at 70, 100 and 160 micrometre wavelengths. The line drawing superimposed on the Herschel image gives a schematic representation of the location and orientation of the star, planets and disc, albeit not to scale. GJ 581â€™s planets have masses between 2 and 15 Earth masses and are all located within 0.22 Astronomical Units (AU, where 1 AU is the distance between Earth and our Sun) of the central star. Minus a Jupiter-like gas giant, a vast debris disc extends from approximately 25 AU to 60 AU.
