"[Our philosopher] asserted that he knew the whole secret...[H]e surveyed the two celestial strangers from top to toe, and mantained to their faces that their persons, their worlds, their suns and their stars, were created solely for the use of man. At this assertion our two travelers let themselves fall against each other, seized with a fit of...inextinguishable laughter"
-- Voltaire (1752)

'Exocomets' Common Across Milky Way Galaxy | Space.com
Comets may be as common as alien planets in star systems throughout the Milky Way galaxy, scientists say.
Astronomers have spotted likely comets around six faraway stars, bringing the total number of systems now thought to host the so-called “exocomets” to 10. It’s likely that all 10 of these systems also harbor alien planets, suggesting that comets and exoplanets are often found together, as they are in our own solar system, the new study found.
