Alien Comet May Have Infiltrated the Solar System 208 208

New Scientist has a piece about Comet Machholz 1, whose uncommon molecular composition suggests, but does not prove, that it may be an interloper 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."

Comment: Which means that 82% notice that it isn't HD (Score 1) 603 603

Really? That's a great number. People aren't putting screens side-by-side and comparing, they are simply assuming it "must be HD".

What is amazing is that if 18 don't notice that it isn't... then a whopping 82% notice! Even with little experience and no side-by-side. This is a large number!
