Through the initial part of the second of the #RoyalInstitution #ChristmasLectures this year, I was preparing to moan that they had focussed on the possibility of life on the (major) Solar planets, and missed the idea that #ArthurCClarke popularized via _2010_.

I should not have been so pessimistic.

They went full throttle into the idea of the possibility of extra-terrestrial life not only on #Europa, but also on #Enceladus and #Titan.

Excellent.

Interestingly, since two of the three criteria for IAU Solar planets don't apply to the moons of Saturn and Jupiter *either*, we don't get to entirely rule out dwarf planets like #Ceres yet. They didn't get into that, though.

And like the first lecture was marred by the repeated use of 'criteria' as a singular noun, the second was marred by Maggie Aderin-Pocock repeatedly asking whether people thought that there might be 'life in the Solar system'. 'Criteria' is plural and Terra is in the Solar system, Maggie. (-:

The only #asteroid known to have been gravitationally rounded is #Ceres, now classified as a #DwarfPlanet, and discovered on #ThisDayInHistory in 1801 by the Italian priest #GiuseppePiazzi. Fans of #TheExpanse series know we should have already hollowed it out and colonized it.😜

Vandaag 10 jaar geleden https://sailing-dulce.nl/home/article-4709 ##dysonring #SETI #ceres #ruudlapré Donderdag 10-12-2015 Vanaf de ontdekking van vreemde signalen uit de richting van ster #KIC8462852 bij het sterrenbeeld Zwaan, gingen er opgewonden speculaties door de wereld van astronomen. Kon er misschien sprake zijn van een Dyson Ring en van een buitenaardse beschaving? Ik schreef er een paar keer over. Sinds die ontdekking heeft men naar een verklaring voor de merkwaardige helderheidsveranderingen van de..
