Is there life on other planets?
Marble in the Sky: the Hunt for Another Earth The Search for Life When we find life, how will we know? When we analyze light shot by a star through the atmosphere of a distant planet—a technique known as spectroscopy—the effect looks like a bar code.
Life in the Universe: What are the Odds?
Our galaxy is crowded with exoplanets – planets around other stars. A healthy percentage of them are small, rocky worlds, of a similar size and likely similar composition to our home planet.
Does life exist outside of the solar system?
Big Questions > Does life exist outside of the solar system? Since humans first looked to the cosmos, we have wondered if life exists elsewhere in the Universe. Scientists and engineers at the Center for Astrophysics | Harvard & Smithsonian may soon be able to answer that question. Our Work 1.3%.
Are We Alone?
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 on Other Planets: What is Life and What Does It Need?
Feature | June 20, 2023 One day, perhaps in the not-too-distant future, a faraway planet could yield hints that it might host some form of life – but surrender its secrets reluctantly. Our space telescopes might detect a mixture of gases in its atmosphere that resembles our own.
Finding Life Beyond Earth is Within Reach
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. What are the next steps to finding life elsewhere?
Life on other planets?
The Great Galaxy M–31 in the constellation Andromeda. This is the nearest galaxy to our own, and resembles it in many ways. The dark rifts are enormous cosmic dust clouds from which stars are thought to form. In each galaxy there may be 100 million planets on which life exists.
Exoplanet Exploration: Planets Beyond our Solar System
Exoplanet Exploration Program. NASA’s science, technology and mission management office for the exploration of exoplanets. The program’s primary goals, as described in the 2014 NASA Science Plan, are to discover planets around other stars, to characterize their properties and to identify planets that could harbor life.

NASA’s Search for Life: Astrobiology in the Solar System and
Viking 1 and 2. Over 45 years ago, the Viking Project found a place in history when it became the first U.S. mission to land a spacecraft safely on the surface of Mars. Viking 1 and 2, each consisting of an orbiter and a lander, were NASA’s first attempt to search for life on another planet and thus the first mission dedicated to astrobiology.
