#77 - November 2018 Part 1

The Discussion: Jeni's tells us about her gig at the Cardiff Book Talk and an upcoming talk at Usk Astronomical Society, Paul had a hairy moment giving a talk on the Herschels only to find their descendants in the room and we run through listeners' emails

The News: Rounding up the space and astronomy news this month we have:

  • Low metallicity stars seem to harbour the rocky exoplanets
  • A possible satellite galaxy to Mirach's Ghost may have been discovered by amateur kit
  • Aliens may not be green but purple
  • A plume-like cloud of water ice over Mars
  • A review of the Galileo data shows no signs of cryovolcanic plumes on Europa
  • The slowest rotating pulsar found
  • Magnetism around Cygnus A supermassive black hole gives us some clues
  • Has the first exomoon been discovered?

Sky Guide: Taking a look at the astronomical objects above our heads this month that you can enjoy with a small telescope or binoculars.

Paul: Saturn, Mars, Uranus, Neptune & a risky greatest elongation of Mercury on 6th November. And Comets 46P Wirtanen and 38P Stephan-Oterma may well provide some distractions too.

Ralph: Northern Taurids meteor shower peaks on 12th November and the Leonids peak on the 17th.

Jen: Mirach's Ghost in Andromeda and two galactic members of the Local Group NGC147 & NGC185.

And we finish off with a spotlight on Venus which will be its brightest all year at the end of the month.

Q&A: Listeners' questions via email, Facebook & Twitter take us on a journey into the astronomy issues that have always plagued our understanding or stretched our credulity. This month we take a look at accepted wisdom vs the evidence:

Did a collision with the Earth create the moon? Is it fact or still a hypothesis? Andrew Osborn in London.
