Using the Very Large Telescope Interferometer, astronomers have discovered exozodiacal light close to the habitable zones around nine nearby stars. This light is starlight reflected…
New research details the discovery of a streamer of gas flowing from a massive outer disc toward the inner reaches of the double star system…
Yale astronomers and the Planet Hunter program have discovered a low-mass, low-density planet that has a highly inconsistent orbit time around its sun. The new…
A new laser-based technology known as the green astro-comb will allow astronomers to determine whether distant exoplanets they discover are rocky Earth-like worlds or less…
Astronomers from the Harvard-Smithsonian Center for Astrophysics studied the debris disc around τ Ceti, revealing that a Jupiter-mass planet could not be present in this…
A team of astronomers used NASA’s Hubble Space Telescope to make the most detailed global map yet of the glow from a turbulent planet outside…
A new study details the orbital architectures of Kepler systems having multiple planet candidates, revealing 899 transiting planet candidates in 365 multiple-planet systems and providing…
Using the combined power of NASA’s Spitzer, Hubble and Kepler space telescopes, researchers have discovered clear skies and water vapor on a Neptune-size gaseous exoplanet…
A new study from NASA’s Chandra X-ray Observatory shows that a giant exoplanet, WASP-18b, is making the star that it orbits act much older than…
Using an altitude-dependent photochemical model with the enhanced lower boundary conditions necessary to carefully explore abiotic oxygen and ozone production on lifeless planets with a…
This new four minute ScienceCasts video examines how researchers are beginning to measure exoplanets with extraordinary precision. ScienceCasts: Sizing up an Exoplanet: Astronomers are not…
Scientists have made most precise measurement ever of the radius of a planet outside our solar system, confirming Kepler-93b as a “super-Earth” that is about…
Using the Hubble Space Telescope, astronomers reveal that three exoplanets that were thought to be ideal candidates for detecting water vapor in their atmospheres contain…
Scientists are taking a new approach in the search for extraterrestrial intelligence, studying exoplanet atmospheres for signs of pollution. Humanity is on the threshold of…
Astronomers from the Harvard-Smithsonian Center for Astrophysics have discovered a transiting exoplanet with the longest known year, circling its star once every 704 days. Astronomers…
With the help of an amateur astronomer, an international team of scientists has discovered a new and unusual exoplanet. Thiam Guan or ‘TG’ Tan is…
Scientists gathered at NASA Headquarters to discuss the next steps to finding life beyond Earth, and outlined NASA’s roadmap to the search for life in…
Using data from HARPS-TERRA, the Planet Finder Spectrograph and the UCLES echelle spectrograph, astronomers have discovered a new potentially habitable Super-Earth around the nearby red-dwarf…
