Edwin Rod
 

Hi everyone

 

Another busy month and here in New Zealand things seem to be getting back to life as normal and were looking at moving down to level 1 next month.

Lots of interesting research this month, from a looking at the outer solar system small objects to research on the proposed “Planet 9”. Again there is some interesting ones looking at exo planets and solar system dynamics.

Anyway I’ll leave you all to read the ones that interest you most

Cheers Edwin

Strangest of All Anthology of Astrobiological SF

Edwin Rod
 

Hi All

This Sci Fi E-book caught my attention today and looks very interesting


IntroductionJulie NovákováIs anyone out there?This is an age-old question we are yet to answer.Speculation on alien life is nothing new. The Greekatomists considered the plurality of worlds and “otherearths inhabited by different tribes of men and breeds ofbeasts”1; 16th century Italian priest and occultist GiordanoBruno speculated about “infinite multitude of worlds”2; thefamous philosopher Immanuel Kant wrote in his Critique ofPure Reason that he would bet everything that at least someof the known planets were inhabited.Nor is science fiction working with the idea of lifeelsewhere or not quite as-we-know-it anything new. One ofthe first such works was penned by the great JohannesKepler himself and published posthumously. The novelSomnium tells a story of a boy, who’d studied astronomywith Tycho Brahe, and the boy’s witch mother, who hadlearned from a demon that the Moon (“Levania”) isinhabited. They both undertake the shocking journey to visitit, and there is an abundance of description of both thecreatures of the Moon and – in this case quite accurately, inaccord with science of that time – the Earth seen from there.The 17th and 18th century saw an increase of stories oflife elsewhere in space, and after the birth of modern science

The Dark Side of Light
Published by Damien McNamara

Hi everyone here is a interesting book Damien has written and offered to share with us to read.

Being a similar age to Damien, I too can remember seeing Halley's comet and following the Voyager missions as a kid during the 80s, then Shomaker hitting Jupiter while I was a high school/College in the 90s.

It looks like a lot of work and an interesting read.

Cheers Edwin


Aprils newsletters and Star Charts

Edwin Rod
 

Hi everyone

Please find all the usual newsletters and star charts attached, lots to have a look at this month and the new Kepler planet is one to watch as an interesting discovery. Again here is no shortage of interesting research this month too.

 

Last month’s email sure feels a long time ago, and how life along with the economy has changed, NZ is moving to alert level 3 from tomorrow (28/04/2020), after 33 Days in complete lockdown, we are slightly easing restrictions. It has been a tough time and the news last night of losing one of my long time astronomy friends was hard too, It was health related and not due to Covid-19.

Take care everyone

March Newsletters and Starcharts

Edwin Rod
 

Hi Everyone

Please find this month’s newsletters and Starcharts attached. There is some interesting papers looking at Icy moons, and even Mercury.

Current events this week have been moving fast, and have taken away from doing any more of a detailed write up. I have added in a few links and papers about Covid-19 along with the usual astronomy research and news items.

New Zealand is an hour away from a Covid-19 lockdown for 4 weeks maybe longer? Were ready to self isolate here and take care everyone.

 

Cheers Edwin

Hi Everyone

 

The usual starcharts and newsletters are attached for the month, along with two interesting papers on Anthropology one takes a look at Easter Island and another the DNA of people outside of Africa. There is an interesting look at Zealanada our small continent mostly submerged. There is also a look at why many Sub Neptune planets are the size they are, and perhaps the distant proposed Ice Giant could fit into this category of planet too.

 

Again there is no shortage of interesting research out this month but if I had to pick out a personal highlight it was the paper looking at the search for an outer ice giant in our solar system. If you’re interested in exo planets, Seti and Red dwarfs there will be lots to keep you occupied!

Hi everyone

Please find this month’s research and news items attached below, along with the star charts too.

 

It’s almost the summer solstice, but far from it here in Wellington tonight!

We had a week of hot weather that was very humid and now cool south-westerly! Forget seeing the stars for a while here!

 

If you happen to be in Nelson over the holiday break this sounds great.

I’m interesting to read the one on Exo moons tonight, and as always there is a range of interesting things to catch up on. A look at the evolution of the solar system, and again some interesting papers on exo planets and Red Dwarfs, along with a look at quantum mechanics.

Andrew also has a few updates I have included as well looking at Mars and other subjects.

I hope you all have a great holiday and Christmas break

Cheers Edwin

A few highlights from the Astrophotography weekend

Hi everyone

It was another stunning weekend away just the Saturday night for myself, however everyone else had a great Friday night with clear skys. It was nice to get the scopes and DSLR out.

Transit of Mercury - A few photos of the transit and trip

Edwin Rod
 

Here are a few highlights of the trip north from Wellington to enjoy the Transit and tomorrow I'm heading up for one night for the NZ astro photography weekend

Transit of Mercury
https://sciblogs.co.nz/out-of-space/2019/11/10/how-nz-was-put-on-world-maps-using-a-transit-of-mercury

On 9 November 1769, Cook landed on the shores of the bay to observe a Transit of Mercury. In 1919, an area of land around Shakespeare Cliff was set aside, and a small memorial was constructed, based on the erroneous notion that it was the location of Cook's observations. But the actual site of Cook's landing and observation was the eastern end of Cook's Beach, near the Purangi estuary.

Hi everyone

Please find all the regular newsletters attached, along with starcharts and a look at Titan.

Wellington finally had a Summers day today! There have been a lot of cold South westerly winds over September and October this year, The air has bene very hazy today and we need to thank our friends over the Tasman for their dust and smoke, I’ve attached a satellite photo to show Its not just my imagination.  

Well it sure has been a busy month this one. We were lucky enough to do a week’s trip away to aptly named Mercury bay to watch this month’s Transit of the Planet, I have managed to place a few cellphone photos up from the trip, however this month has been rather busy on the personal front so I have not yet had a chance to look at the Nikon P900 or do a full write up on the Transit and send out photos so watch your inbox for another email on that subject.  

We have two interesting updates from Andrew B, UK Kent this month to share. He takes a look at Asteroid 162173 Ryugu (1999 JU3), an interesting mission I have been following. KBO 486958 Arrokoth now has a name and this is an interesting object, Andrew again brings us up to speed.

 

There was no shortage of interesting stories this month and research out.

The hunt continues for an outer Ice giant world, and this month the team found a pair of Brown Dwarfs around 70Ly away an interesting discovery if like myself you’re interested in these objects.

Panspermia again has a look in with research at exporting life out of the solar system.

If you’re interested in exo moons, Red Dwarfs and life on other planets then there are a range of links this month to follow up on.

Anyway its get late here so I better let you read through what interested you from this month.

Cheers Edwin

The trip has been amazing thanks to our hosts. Its overcast now for the star party, and not sure for the Transit in the morning.
