Sep 29, 2023 · Nasa's James Webb Space Telescope (JWST) recently detected tantalising hints at life on a planet outside our Solar System - and it has many more worlds in its sights. Numerous missions that are...
Mar 5, 2020 · A new study by a University of Tokyo professor combines biological and cosmological models to explore how life's building blocks could form in the universe. He argues that rapid inflation of the universe increases the chances of complex RNA structures, but also makes life less likely in our neighborhood.

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.
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.
NASA explores the possibility of life on exoplanets using transit spectroscopy, which detects gases and chemicals in their atmospheres. Learn about the challenges, methods, and candidates of the search for life as we know it or as we don't.
Explore how astronomers search for life in the cosmos, from finding and characterizing exoplanets to looking for signs of intelligent life. Learn about the diversity of star systems, planets, and interstellar chemistry, and the challenges and possibilities of life in the universe.
