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'.

NGC 2964 + NGC 2968 (Galaxy) Right ascension: 9h 44m Declination: 31° 54' Constellation: Leo Date/time: 2014.03.28 21:30 UT Equipment: 12" f/5 Newtonian FoV: 24' Magnification and filter(s): 167x Seeing: 3/10 Transparency: 3/5 SQM: 21.13 m/as2 Temperature: 6°C Humidity: low Wind: breeze Sight: 3 - definite details, interesting look Difficulty: 4 - hardly visible, dark adaptation and very dark skies needed, averted vision is required to see details Position: 2 - easy, bright star nearby Location: Nádasdladány, Hungary Observer: Ferenc Lovró Description: Interesting but very faint pair of galaxies in the constellation Leo the lion. Both of them is oval, the galaxy NGC 2964 to the SW has a very delicate star-like core. This galaxy also displays an interesting detail mostly with the averted vision: its NE side is a bit brighter than the other, forming a triangular shape. Its even fainter companion, the NGC 2968 does not show any detail. Hi-resolution image: [ reversed sketch | original sketch ]
