August 2025 research and news items The big news this month is the giant planet around Alpha Centauri A, I will be looking forward to more information on this planet which appears to be a Saturn Gas giant, not was I was expecting to find. Atmospheres around planets orbiting close in to small red Dwarf stars are not looking to promising, I also found an older paper on the subject when reading about the Trappist Planets. Keep a watch of observations on interstellar comet 3I Atlas. Some interesting news articles out too this month and a few of top picks are below. A lot of research to read and study here A Candidate Giant Planet Imaged in the Habitable Zone of Cen A Orbital and Physical Properties https://arxiv.org/abs/2508.03814 A Candidate Giant Planet Imaged in the Habitable Zone of Cen A Binary Star Modeling https://arxiv.org/abs/2508.03812 Imaging low-mass planets within the habitable...
September 2024 News and research papers Hi Folks Not too many papers this month that I’ve found but there are some really interesting ones well worth a read this month. The Earth having a ring was interesting. There was a look at F type stars I’m thinking Sirius here, perhaps below 2 solar masses and you could have a nice exo planet for life. There is also a look at the fauna of long lost NZ, and a reasonable explanation of the Neanderthals disappearing too, I’m thinking sure the ice ages numbers couldn’t have been too high.
