Are We Alone? / The Search For Life – Exoplanet ~ 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. Our galaxy likely holds trillions. But so far, we have no .

Why We Search / The Search For Life – Exoplanet ~ Introduction. Whether life exists beyond Earth is one of the most profound questions of all time. The answer will change us forever, whether it reveals a universe rich with life, one in which life is rare and fragile, or even a universe in which we can find no other life at all.

The Habitable Zone / The Search For Life – Exoplanet ~ Other similarities to Earth come into sharper focus in the search for life. Many rocky planets have been detected in Earth’s size-range: a point in favor of possible life. Based on what we’ve observed in our own solar system, large, gaseous worlds like Jupiter seem far less likely to offer habitable conditions. But most of these Earth-sized worlds have been detected orbiting red-dwarf .

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.

Can We Find Life? / The Search For Life – Exoplanet ~ Are we alone in the universe? So far, the only life we know of is right here on our planet Earth. But we’re looking. The big question – Is there life beyond Earth? – comes with an ironic asterisk: we don't really have a universally accepted definition of life itself. That said, we might not need one. We need only detect the telltale signs of life in an exoplanet atmosphere, and we have a .

Are we alone in the universe? Revisiting the Drake ~ And it shows that unless the odds of advanced life evolving on a habitable planet are astonishingly low, then human kind is not the universe’s first technological, or advanced, civilization. The paper, published in Astrobiology, also shows for the first time just what “pessimism” or “optimism” mean when it comes to estimating the likelihood of advanced extraterrestrial life. “The .

Exoplanet Exploration: Planets Beyond our Solar System ~ How NASA is searching for life beyond Earth. Read more › Read More Galaxy of Horrors Tour of some of the most terrifying destinations in our galaxy – and beyond. Download our new posters based on real NASA science if you dare. Posters & more › Posters & More About Half of Sun-Like Stars Could Host Rocky, Potentially Habitable Planets According to new research using data from NASA’s .

Roadmap / Astrobiology @ NASA / Research / Astrobiology ~ Does life exist elsewhere in the Universe? How do we search for life in the Universe? Over the past 50 years, astrobiologists have uncovered a myriad of clues to answering these Big Questions. Since the astrobiology community published its last Astrobiology Roadmap in 2008, research in the field has focused more and more on the link between the “astro” and the “bio” in astrobiology .

Does Life Exist Elsewhere in the Cosmos? ~ The search for life on other worlds has consumed our imaginations for decades. Humans feed on a constant supply of science fiction stories and movies such as Star Wars, Star Trek, Close Encounters of the Third Kind, which all cheerfully suggest that they are out there. People find aliens and the possibility of alien life are fascinating topics and wondering if aliens have walked among us is a .

Your Guide to Exoplanets / The Planetary Society ~ These worlds are a prime target for the search for life beyond Earth. You can help The Planetary Society advocate for WFIRST, NASA’s next exoplanet mission. You can also support our efforts to help scientists find 100 Earth-sized exoplanets around nearby stars. Why study exoplanets? For centuries, fictional depictions of planets orbiting other stars have fired our imagination. From the .

About / Astrobiology ~ The search for life beyond Earth is so intertwined with other NASA goals (and is so interdisciplinary by nature and design), it can never really be separated or isolated from them. The Cassini mission to Saturn discovered plumes spitting out of the moon Enceladus, and the Hubble Space Telescope did the same for Europa. Both plumes tell of an inner water world, and so are important to planetary .

SETI & the Search for Extraterrestrial Life / Space ~ Most SETI searches focus on the hunt for radio or optical signals that can signify highly evolved alien life. Because life on Earth arose within 100 million years after the planet was habitable .

Best Astronomy and Astrophysics Books to Read in 2019 / Space ~ A new book titled "Exoplanets: Diamond Worlds, Super Earths, Pulsar Planets and the New Search for Life Beyond Our Solar System" (Smithsonian Books, 2017) explores the history of exoplanet .

Our Living Planet Shapes the Search for Life Beyond Earth ~ The knowledge and tools NASA has developed to study life on Earth will be a great asset to the study of planets beyond our solar system.

Overview - Exoplanet Exploration: Planets Beyond our Solar ~ Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. We know from NASA’s Kepler Space Telescope that there are more planets than stars in the galaxy. By measuring exoplanets’ sizes (diameters) and masses (weights), we can see compositions .

Search for Extraterrestrial Intelligence – Wikipedia ~ Search for Extraterrestrial Intelligence (englisch für Suche nach extraterrestrischer Intelligenz, auch kurz SETI genannt) bezeichnet die Suche nach außerirdischen Zivilisationen.Seit 1960 werden verschiedene wissenschaftliche Projekte betrieben, die unter anderem den Radiobereich des elektromagnetischen Spektrums nach möglichen Anzeichen und Signalen technischer Zivilisationen im All .

Life probably exists beyond Earth. So how do we find it? ~ With next-generation telescopes, tiny space probes, and more, scientists aim to search for life beyond our solar system—and make contact.
