New Scientist has a piece about Comet Machholz 1, whose uncommon molecular composition suggests, but does not prove, that it may be aninterloper from another star system."Comet Machholz 1 isn't like other comets. David Schleicher of the Lowell Observatory in Flagstaff, Arizona, measured the chemical makeup of 150 comets, and found that they all had similar levels of the chemical cyanogen (CN) except for Machholz 1, which has less than 1.5% of the normal level. Along with some other comets, it is also low on the molecules carbon-2 and carbon-3."
