August 2024 News and research papers.

Hi Folks

 

It’s been a stormy night here, and I found myself reading up on the latest research from New Horizons, providing insight to how dark the universe is. There was also an interesting one tonight regarding galactic Seti and looking beyond out milky way. Juice also made a flyby recently, on its way to Jupiter.  I’ve noted down a number of other interesting ones too below for you to read.  

 

Tonight’s storm!

Interesting News items

 

 

Drilling into the Ocean clearly is for the far future, but a rover that can sample under the surfaces and analyze samples in detail is a mission I would support.
