Apr 22, 2024 · Apr 22, 2024. Editor. Hugh Brennan. We don't know when, or even if, we'll find life beyond Earth, but NASA scientists continue the hunt among the thousands of exoplanets confirmed in the galaxy so far.
Sep 29, 2023 · 29 September 2023. By Pallab Ghosh,Science correspondent. Share. ESA. Europa, one of Jupiter's icy moons is the most likely place in our solar system to be home to alien life. Many astronomers...
Jul 14, 2014 · NASA and its partners are using current and future telescopes to find and characterize exoplanets that could harbor life. Learn about the scientific and technological advances that enable the search for potentially habitable worlds among the stars.
Mar 5, 2020 · If there's one thing in the universe that is certain, it's that life exists. It must have begun at some point in time, somewhere. But despite all we know from biology and physics, the exact...

Exoplanets, or planets in solar systems other than our own, sometimes orbit directly between the Earth and their host star. When the planet orbits in front of its star, it blocks a small amount of light. CfA scientists use the Transiting Exoplanet Survey Satellite (TESS) and the Kepler space telescopes as well as the ground-based robotic telescopes...
Institute for Theory and Computation scientists at the CfA work on identifying the exoplanets that are most likely to harbor life. The orbit must lie in the “habitable zone” where the exoplanet’s surface is just the right temperature for liquid water to exist. Every form of life we know requires liquid water, so an exoplanet too close or too far fr...
The G-CLEF or GMT-Consortium Large Earth Finder, a next-generation spectrometer planned for use on the GMT, is our newest tool for measuring the starlight filtered through the atmosphere of an orbiting exoplanet. Using this instrument, scientists will soon be able to measure the chemical composition of a small rocky exoplanet’s atmosphere. Such an ...
The Center for Astrophysics explores the origins, composition and detection of life on other planets. Learn how they use telescopes, models and instruments to find exoplanets in the habitable zone and search for biomarkers.
May 18, 2020 · A Columbia astronomer uses Bayesian statistics to estimate the odds of life and intelligence emerging beyond Earth. He finds that life is common but intelligence is rare, based on Earth's history and evidence.
So far, the only life we know of is right here on planet Earth. But NASA is looking for signs of life in our solar system and on some of the the thousands of planets we've discovered beyond it, on exoplanets. We can probe alien atmospheres for biosignatures, which could indicate life below.
