Occasionally, I get a letter from someone who is in 'contact' with aliens. I am invited to ask them anything. And over the year's I've prepared a little list of questions. The aliens are very advanced remember. So I ask things like, 'Please provide a short proof of Fermat's Last Theorem'. I write out the simple theorem equation with the exponents. It's a simulating exercise to think of questions to which no human today knows the answers, but where a correct answer would be recognised as such. It's even more challenging to formulate such questions in fields other than mathematics. Perhaps we should hold a contest and collect the best responses in '10 Questions to Ask an Alien'.

61 Cygni (Binary star) Also known as: 61 Cyg, Piazzi's Flying Star Right ascension: 21h 7m Declination: 38° 48' Constellation: Cygnus Date/time: 2012.08.19 20:30 UT Equipment: 4.5" f/8 Newtonian FoV: 14' Magnification and filter(s): 150x Seeing: 7/10 Transparency: 4/5 SQM: 21.37 m/as2 Temperature: 16°C Humidity: dry Wind: none Sight: 3 - definite details, interesting look Difficulty: 1 - instantly visible, no dark adaptation or averted vision needed Position: 1 - very easy, many bright stars nearby Location: Lipótfa, Zselic, Hungary Observer: Ferenc Lovró Description: Spectacular yellow binary star, makes a nice couple especially at low magnification. The fainter companion is a little bit bluish. The primary aim for this sketch is to observe this star once every year from now on on the approximately same day in order to display how this star drifts through space compared to the other field stars - this is one of the fastest apparently moving star with about 5" per year.
