Our multi-stellar system? Most stars form in multiples. Where are our sister stars? All of such sisters should be of somewhat similar mass, main sequence, and hence not supernova material; perhaps harboring life, and even culture? Such sisters must not be so far off. Hence might they be detectable by looking for 'cold' Jupiters? Use an infrared telescope to evaluate the luminosity and size of such gas giants, and through comparison, see if any are close. Such star(s) should be much less than 1 light year, and hence within the Oort Cloud. Thus if such sister stars are within our Oort Cloud, it would seem then to be a distorted cloud, common to such multiple star systems.
