Looking for Another Earth? Here Are 300 Million, Maybe
5 nov. 2020Scientists estimate there are some 300 million potentially habitable planets just in our own galaxy. NASA On average, the astronomers calculated, the nearest such planet should be about 20…
Kepler’s Tally of Planets
NASA’s Kepler mission has discovered more than 1,000 confirmed planets orbiting distant stars. Planets with known sizes and orbits are shown below, including Kepler 452b, a planet in the habitable zone of its star.

Why We Search | The Search For Life – Exoplanet Exploration
For a world to have life as we know it, we understand that it would need liquid water on the surface, however, it might not look anything like Earth. The planet would most likely exist in the habitable zone of the star it orbits, where it is neither too close nor too far from its star.

Are We Alone? | The Search For Life – Exoplanet Exploration
9 févr. 2023Why We Search. 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. But what we don’t know fills volumes. Observations from the ground and from space have confirmed thousands of planets beyond our solar system.

Life in the Universe: What are the Odds? – Exoplanet Exploration
We have yet to find another Earth with life, intelligent or not. Observing signs of possible microbial life in exoplanet atmospheres is currently just out of reach.

NASA Is Taking a New Look at Searching for Life Beyond Earth
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.

Finding Life Beyond Earth is Within Reach – NASA
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. This basic question about our place in the Universe is one that may be answered by scientific investigations.

Life probably exists beyond Earth. So how do we find it?
Today we have confirmed about 4,000 exoplanets. The majority were discovered by the Kepler space telescope, launched in 2009. Kepler’s mission was to see how many planets it could find orbiting … lesoutrali bot
