August 2025 research and news items

  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...

March 2023 News research

Hi Everyone   Please find this month’s News and Starcharts attached along with all the interesting research.   There is a good look at the Trappist planets that I myself still need to read, these papers also tie in well with the Exo Venuses. Following on from that a few goon ones on Exo planets too. With all the posts about starlink it’s been a real interest for many people and there is a good paper on the issue here too. I feel like I have a lot of reading to do this month. Amazingly it’s a nice mild clear night tonight too here in Wellington, we might be in for a stormy winter too.   Thanks Edwin   Research papers       A good update on the Trappist planets here Thermal Emission from the Earth-sized Exoplanet TRAPPIST-1 b using JWST https://www.nature.com/articles/s41586-023-05951-7     The Demographics of Terrestrial Planets in the Venus Zone https://arxiv.org/abs/2302.03055     A New D...
