News and Research items for February 2025
Hi everyone a lot of interesting papers out this month, that troubling asteroid has moved right off course from the Earth. The Lunar Eclipse is happening on the 14th so let hope the weather is good.
There is also a telescope Robin is selling too included in a separate flyer.
Research papers
It seems like we were thinking about a planet on this type of orbit just the other day, Its not going to be a "Earth like" world and most probably an hycean/ocean super Earth type of Planet. The Atmosphere and vast Ocean could make it quite a pleasant place, but does that equate to microbial life in the ocean?
