Based on a statistical analysis of all the Kepler data, astronomers now estimate that one in five stars like our Sun have planets about the…
The latest analysis of Kepler Space Telescope data has revealed the discovery of 833 new candidate planets; ten of these candidates are less than twice…
Using planetary models based on measurements of our sun’s carbon-to-oxygen ratio, researchers found that planets rich in carbon, including so-called diamond planets, may lack oceans….
Astronomers used data from NASA’s Spitzer and Kepler space telescopes to produce a very low-resolution ‘map’ of the exoplanet Kepler-7b. Scientists using data from NASA’s…
A new study demonstrates how to distinguish between cloudy mini-Neptunes and volatile-dominated super-Earths based on the differences in the wing steepness and relative depths of…
This short narrative looks back on how NASA engineers revamped the Spitzer Space Telescope to probe exoplanets. Now approaching its 10th anniversary, NASA’s Spitzer Space…
By using habitable zone and stellar evolution models, astrobiologists from the University of East Anglia have estimated that habitable conditions on Earth will be possible…
New research presented to the European Planetary Science Congress at UCL aims to explore how atmospheric biomarkers from faraway planets might be detected in the…
