How astronomers discovered Kepler-452b, an Earth-like planet orbiting a Sun-like star
The discovery of a habitable planet like our own marked a milestone in the journey to find a second Earth.
Kepler space telescopes’s last planets found by citizen scientists sifting through archive data
The three exoplanets were detected when the now-defunct spacecraft was ‘running on fumes’.
A history of the Kepler space telescope
The Kepler space telescope is retired, but it leaves behind a wealth of data and information about planets orbiting stars beyond our Solar System.
Citizen scientists find rare exoplanet in Kepler data
The Exoplanet Explorers website helped to uncover a world which lies in a size 'gap' - the range between 1.5 and two Earth radii where few planets have been found. The planet was hidden in data that had previously been throw out to prevent errors, but which could now be analysed safely.
Interview: exoplanet-hunting with Kepler
The Kepler space telescope may have run out fuel, but for NASA scientists there is alot of important work yet to be done. We spoke to Kepler scientist Geert Barentsen to find out what the mission has achieved, and what lies ahead.
How the Kepler space telescope came to be
