Edwin Rod
Hi everyone
Please find all the usual newsletters, starcharts and papers attached. Its Covid level level 2 for us in Wellington and NZ until Sunday night (29th Aug) and its level 3 for the Auckland region, I have one or two links on Covid for those who might be interesting, in the attached notepad file. There sure is no shortage of interesting articles this month and a lot to get through. Did the Sun form with another star? A binary companion? Interesting research suggests it might have, with intriguing implications for the proposed outer ice giant Planet. Ganymede has always been a Moon of interest for me and this month there is a look at a big impact basin on the moon and the tidal heating of Jupiter’s Moons. There is also an interesting look at a Star that is just big enough to be on the main sequence. How many habitable planets can you fit around a Star? Its an interesting question that is answered this month. There is a look at a very high density Neptune planet and a look at the Trappist planets too.
Andrew from the UK has also summed up nicely some top stories from the month too.
Cheers Edwin
