14. Juli 2014 · Many scientists believe we are not alone in the universe. It’s probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone — just as it did here on planet Earth.
If you can figure out how to isolate and identify life-forms that thrive in similarly extreme surroundings on Earth, you're a step ahead in searching for life elsewhere.
1. Aug. 2022 · The search for life beyond the Earth is being carried out using a variety of techniques in three distinct realms of space. The best near-term prospect for the detection of life is the detection of biomarkers in exoplanet atmospheres.
25. Sept. 2018 · Thanks to NASA’s Kepler mission’s discovery of thousands of planets beyond our solar system,including some with key similarities to Earth, it’s now possible to not just imagine the science fiction of finding life on other worlds, but to one day scientifically prove life exists beyond our solar system.
22. Apr. 2024 · It outlines scientific priorities for the decade ahead, including the discovery and exploration of habitable planets. The observatory’s imaging capability, well beyond that of any existing space telescope, would be used to observe 25 potentially Earth-like planets to search for signs of life.
Observations from the ground and from space have confirmed thousands of planets beyond our solar system. The search for life beyond Earth is really just getting started, but science has an encouraging early answer: there are plenty of planets in the galaxy, many with similarities to our own.
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.
