Spelunking on Mars? I’m sure it could be fascinating, but it bears keeping in mind that environment doesn’t produce life.
“Model accounts for scarcity of planets with masses between super-Earths and mini-NeptunesComputer simulations by Rice University scientists and their collaborators are the first to integrate a model of planet formation and evolution that explains two puzzling observations of exoplanets orbiting distant stars: the rarity of worlds about 1.8 times larger than Earth and the near-identical size of adjacent planets in hundreds of planetary systems.
“When was the Earth ready to open shop, and how long can life on Earth take these perfections for granted?”
“The narrow window for perfect solar eclipses leads us to consider the matter of timing as evidence of design. Where else are coincidences of timing discernable?”
“The subsurface of Mars during the Noachian period was likely to have been habitable for microorganisms that feed on hydrogen and produce methane, according to new research.”
Small mass, red dwarf stars present several challenges to supporting life.
“A super-Earth planet has been found near the habitable zone of a red dwarf star only 37 light-years from the Earth.”
Studies of white dwarf stellar remnants provide insight into the systemic chaos that occurs when a star dies.
