This months news and research items

Edwin Rod

Hi everyone


Please find this month’s newsletters and star charts attached. This month there is an interesting number of papers and news items on my favorite class of stars, looking at planets around red dwarfs so plenty to read there. Speaking of Planets news broke of a possible planet around Alpha centauri A which is something we all need to keep a watch on. There is also a look at how many interstellar objects are captured by our solar system. New research on a possible outer planet arrived out this month and it’ too hard to say either way really, as usual Mike Brown had something to say on the subject. Starlink was back in the news and I read a good article from the ESA on re entry times for satellites which was very interesting. I managed to catch the live landing of Perseverance to which was a highlight this month so lots of images there along with news too.


So plenty of papers and news items to keep you all busy reading this month and your probably under some form of Covid lockdown so you will have the time for some reading, Currently were at Level 2 in Wellington (3 In Auckland).  

Cheers Edwin
