Stars with about 45 to 80% the mass of the Sun, so-called K dwarf stars, have previously been proposed as optimal host stars in the search for habitable extrasolar worlds.
Terraforming & Geoengineering
The Early Earth As An Analogue For Exoplanetary Biogeochemistry
Planet Earth has evolved from an entirely anoxic planet with possibly a different tectonic regime to the oxygenated world with horizontal plate tectonics that we know today.
Terraforming And Planetary Engineering: Study Underscores Uncertain Costs Of Iron Fertilization
Editor’s note: It is a common thing to sit back and imagine what other worlds are like, if we can live there, and how we might need to modify the […]
Venus As An Anchor Point for Planetary Habitability
A major focus of the planetary science and astrobiology community is the understanding of planetary habitability, including the myriad factors that control the evolution and sustainability of temperate surface environments […]
ESA Approves EnVision Mission To Venus – The Closest Planet To Earth
ESA’s next mission to Venus was officially ‘adopted’ today by the Agency’s Science Programme Committee. EnVision will study Venus from its inner core to its outer atmosphere, giving important new […]
Short Term Impact of Human Activity During the Anthropocene: The Corona Pandemic Reduced The Melting Of Himalayan Glaciers
Editor’s note: Astrobiologists are often focused on how a planet’s life history shapes the life on it and how that life can, in turn, alter a planet’s life history. Life […]
Exoplanet Climate: It Takes Nothing To Switch From Habitable To Hell
The Earth is a wonderful blue and green dot covered with oceans and life, while Venus is a yellowish sterile sphere that is not only inhospitable but also sterile. However, […]
Turning Earth Into Venus: A Stochastic Model of Possible Evolutions of Terrestrial Topography
Venus may have had both an Earth-like climate as well as extensive water oceans and active (or incipient) plate tectonics for an extended interval of its history. The topographical power […]
Analyze Mass Spectrometry Data With Artificial Intelligence To Assist The Understanding Of Past Habitability Of Mars And Provide Insights For Future Missions
This paper presents an application of artificial intelligence on mass spectrometry data for detecting habitability potential of ancient Mars.
Planetary Biotechnospheres, Biotechnosignatures And The Search For Extraterrestrial Intelligence
The concept of planetary intelligence as collective intelligence is used to consider possible evolutionary paths of biotechnospheres that emerge on the intersection of the technosphere with the biosphere and support […]
