June 2021 News and Research

 

Hi everyone

Please find attached this month’s newsletters, starcharts and some of the highlights.

 

With Juno taking a stunning close up view of Ganymede I have included two interesting papers on the Moon, there is also a link to volcanism on Europa to.

While on the subject of Moons there is an interesting look at Exo Moons some of these could be large worlds in the habitable zone.

There is an interesting look at the possibilities of life on sub Neptune and super earth Planets which I need to read.

The article on the Polar dinosaurs in Alaska was interesting.

Again these are a whole range of interesting news items out this month some of my favourite are below.

 

Winter has arrived here this week in Wellington and were back into Covid Level 2 here hopefully the restrictions end this Monday, things In Sydney and Fiji look concerning and the Auz travel bubble has been paused again too.

 

Cheers Edwin

HUGE COMET DISCOVERY: Astronomers have discovered a comet so big, it might actually be a minor planet. The object, named 2014 UN271, is falling toward the sun for a "close approach" outside the orbit of Saturn in early 2031. Promising signs of outgassing have already been detected. Full story @ Spaceweather.com.

Time to Name a Planet

In celebration of 100 years of the International Astronomical Union, the IAU NameExoWorld  global competition allows any country in the world to give a popular name to a selected exoplanet and its host star. New Zealand has been assigned the planet HD 137388b and its host star HD 137388 and we need your help in choosing names!  You can make a submission here between 1 September 2019 and 30 September 2019 (5:00 p.m. NZST). A panel of judges will select the name of the star and the planet by 30 October 2019 and will make its submission to the IAU by the 31 October 2019. IAU will make it’s final announcement in by 31 December 2019 . The winner will then be notified via email. Please note that entries can only be accepted from people living in NZ during the time of the submission.
