Just supposing there is a God(s) ; are He/ She /It interplanetary or are we likely to experience a similar ruinous manifistation of the discord seen here on Earth as the varoius factions of ‘the Godly’. come together? If so, it may be time to start smelting down the plough-shares again.

How do stellar outbursts affect the planets that orbit them?
Scientists surveyed thousands of stars to understand the impact they have on their orbiting planets’ habitability.
A free-floating planet (FFP) is a planetary-mass object that orbits around a non-stellar massive object (e.g. a brown dwarf) or around the Galactic Centre. The presence of exomoons orbiting FFPs has been theoretically predicted by several models. Under specific conditions, these moons are able to retain an atmosphere capable of ensuring the long-term thermal stability of liquid water on their surface. We model this environment with a one-dimensional radiative-convective code coupled to a gas-phase chemical network including cosmic rays and ion-neutral reactions. We find that, under specific conditions and assuming stable orbital parameters over time, liquid water can be formed on the surface of the exomoon. The final amount of water for an Earth-mass exomoon is smaller than the amount of water in Earth oceans, but enough to host the potential development of primordial life.
Life on Mars may be freeze-dried.
But there’s a solution: freeze-dry it.
In a first-of-its-kind experiment, a team of Japanese researchers freeze-dried samples of mice sperm and sent them aboard the ISS to see how well this crucial element of human life (and, well, a lot of life on Earth) will fair against the harsh radiation of space.
Even after six long years aboard the ISS, the team found that the mice’s space sperm sired equally healthy pups as its terrestrial control. An additional X-ray experiment predicts that this positive outcome could persist with up to 200 years of space radiation exposure.
They’ve only gone and upended a widely held scientific idea.
Lilia Koelemay, a graduate researcher at the University of Arizona, said in a statement about the study that “the detection of these organic molecules at the galactic edge may imply that organic chemistry is still prevalent at the outer reaches of the galaxy, and the [galatic habitable zone] may extend much further from the galactic center than the currently established boundary.”
Koelemay also said, “The widely held assumption was that in the outskirts of our galaxy, the chemistry necessary to form organics just doesn’t occur.”
What’s next — The new finding overturns this assumption, and researchers can now widen the search for life to stars closer to the galaxy’s outer edge, a no-man’s-land of cold matter, isolated stars, and black holes left from long-ago stellar explosions. It’s a place Koelemay says has fewer stars like our life-giving Sun.
