THIS WILL BE A VIRTUAL MEETING

THE MARTIAN DICHOTOMY
- with a nod to Edgar Rice Burroughs

Forget your Olympus Mons, or Valles Marineris, probably the strangest feature on Mars is the distinct difference in elevations between the northern and southern hemispheres.
Known as the Martian Dichotomy, this difference can be up to three kilometres.
Basically is comes down to the north is fairly flat, while the south is mountainous.
Michael will examine the various hypotheses as to why this should be?

VIRTUAL MEETING

Michael Franks

ASTROBIOLOGY :
THE SEARCH FOR LIFE ELSEWHERE IN THE UNIVERSE

Michael will be looking at the evolution of life on Earth. How life - as we know it - works and where we might find life elsewhere. This will include an examination - and explanation - of the infamous Drake Equation! He will look at the history of searching for life on Mars; the first landers on Mars – Viking; the Allen Hills meteor; and other traces of life on Mars. The talk will review the other places where we might life in the Solar System, such as Europa, Titan, Enceladus and Miranda. Then further out into the Universe where exoplanets get a mention.

VIRTUAL MEETING 18.00hrs / 6.00pm

FIAMMETTA WILSON, MANDOLINS & METEORS

Having initially been destined for a life in music (as many ladies were in her time), she then discovered astronomy, and particularly meteors. Between the years 1910 to 1920, she observed about 10,000 meteors and accurately calculated the paths of 650 of them. In 1913, she made an independent rediscovery of Westphal's Comet while it was passing the Earth. After publishing many papers, she was elected a Fellow of the Royal Astronomical Society in January 1916, one of the very few lady Fellows at the time. And she had a direct connection to the Society, and our current meeting place, as she spent all her life, including the observing, in Barnet Lane, Totteridge which is a couple of miles away from the Mitre Inne. 2020 marks one hundred years since her death.

VIRTUAL MEETING VIA ZOOM

ROBERT vs THE FLYING SAUCERS

This slightly odd title (?) reflects the equally odd situation of a certain small town in New Mexico, USA that in the 20th Century boasted two significant 'space events'. One was long term - the arrival of a rocket pioneer who needed the wide open spaces for his experiments. The other event was initially far more short-lived - though the ramifications are still reverberating… More will be revealed during this fully illustrated talk, including the name of that New Mexican town. (In case you still haven't worked that out... it begins with 'R')

This talk was given in 2015 in its original form, but that was five years ago - and this version is modified and updated!

Bob Marriott

For many years - 1991 -2016 - Bob Marrriott was the BAA's Curator of Instruments, and from 2003 - 2017 Director of Instruments and Imaging. He also produced the periodical 'I&I News' (newsletter of the Instruments and Imaging Section). Copies of those, and his own new publication, 'Occasional Notes', can be found and downloaded from his web site www.hamaldemon.com

This will be his first visit to ASH, and looks as if it will be extremely interesting...

THE SILVER-ON-GLASS REVOLUTION

From the mid-seventeenth century until the mid-nineteenth century, telescope mirrors were made of speculum metal – an alloy of copper and tin. (Example above is the Rosse Telescope mirror in the Science Museum) In addition to the age-old process of ‘silvering’ the back of domestic mirrors with a mercury amalgam, experiments in depositing metal films on speculum-metal mirrors and glass were attempted as early as the mid-eighteenth century, but these processes were intended only for aesthetic purposes and were of no use for optics. In the mid-1830s, Justus von Liebig succeeded in depositing a thin film of silver on a surface by chemical means, though this was an incidental effect resulting from his work on aldehydes. By the late 1850s, the process of depositing silver on glass had become sufficiently refined for optical purposes, resulting in a sudden ‘revolution’ in telescope technology.

THE CHANGING VIEW OF THE SOLAR SYSTEM
- AS SEEN BY THE SKY AT NIGHT

Over the 60+ years of The Sky at Night, the programme has covered the Solar System many times. We will see contrasting episodes - 40 years apart! The first is from 1975 : 'The OUTER PLANETS', compared to one from 2017 : 'INTO THE DARK ZONE'

This meeting has moved from September and November 2018

PROJECT ECHO

The first communications satellite to be launched. It was a 'passive' satellite - in that it purely bounced signals - as against re-transmitting them, which 'active' satellites do. Echo was nevertheless an important milestone to world communications. George tells the story

OBSERVING EVENING

As the April Observing Evening went so well, another one for May - before the skies get too bright in the evenings. Check OBSERVING for maps and details.
The Moon - skies permitting - should look similar to the image - a very thin crescent as the Moon is but 2 days old - and it will be very close to Venus.
And there will be a lot more to discover as well

OBSERVING EVENING

This is a first being held on a SATURDAY - we will see how this goes

But potentially a good viewing opportunity, with the Moon being close to new

The outermost planets, Uranus and Neptune, are both well placed for viewing and there is Comet 2107 O1 (ASASSN) near the Pole Star as a possible target
