July 2020 Starcharts News and research

Hi Everyone

 

Please find this month’s newsletters and starcharts attached  

Another month with life here in New Zealand returning to normal post lockdown.

However things around the world and close to home in Melbourne/Victoria the situation isn’t looking good.

There has been another interesting month of research and news to read, a special thanks to Andrew in the UK for his updates on most of the months top interesting news items I’ve included them in usual attachment. There is an interesting look at rocks in Australia and how this can help research similar rock types on Mars this would be an interesting place to do geology. There is also a look at Tides on Titan another look at Europa. As always if you’re interested in exo planets there are a few to read too.

It sure has been a busy month.

Cheers Edwin
