1 lis 2021 · Life on other planets will be under the conditions of those other planets. When “Earth-like” planets, suitable for life, are searched for (and found), there should be an obligatory additional remark − for the Terrestrial form of life or similar forms.
7 lut 2024 · A sample framework, proposed in 2021, includes a scale ranging from 1 to 7, with hints of other life at level 1, to increasingly substantial evidence, all the way to certainty of life elsewhere at level 7.
8 lip 2021 · We discuss the environmental conditions thought to be necessary to support life; calculations of the number of possible habitable planets; ongoing research on the environment of Mars, and efforts to search for life outside the Solar system.
19 lip 2017 · The exploration of other planets has enabled scientists to better understand Earth—past, present, and future. Astrobiology research has convinced me that the discovery of a second genesis of life will yield benefits for humankind, in enabling a deeper understanding of what life is, and could be.
The ultimate goal of NASA’s exoplanet program is to find unmistakable signs of current life on a planet beyond Earth. How soon that can happen depends on two unknowns: the prevalence of life in the galaxy and how lucky we get as we take those first, tentative, exploratory steps.
8 wrz 2015 · By studying the different defense and adaptational mechanisms of organisms in response to their environments, we expand our knowledge about the physical and chemical limits of life, which will enable a target-oriented search for life on other planets.
18 gru 2009 · Regulatory aspects of feedbacks in the collective Earth system, between life and the physics and chemistry of the atmosphere, soils, and oceans, have provided a persistent habitable condition for a vast diversity of life over the past three billion-plus years.
