May 2025 News and research items
The biggest news item this month has to be the probability of a “Planet 9” candidate in the outer solar system and I’m looking for updates on that one, an new dwarf planet has been found out there hinting at a lot more to be found. One subject I’ve tried to do a lot of research into is habitable moon around giant planets and this month an interesting paper on the subject, It turns out 1-2 Au is a great distance.
Social Media – I have been unable to login to the facebook platform the past week keep having the check the notification on your other device message but I don’t have any other devices? Sorry If I have missed any messages or notifications. I see a lot of my Astronomy friends on Bluesky now so feel free to look me up.
