Some of the most interesting exoplanets discovered so far are the “super-Earths,” rocky worlds which are significantly larger and more massive than Earth but still smaller than the […]

'Planet Hunters' Citizen Scientists Discover Distant Exoplanet With Time-Keeping Issues

After analyzing many millions of light curves that were obtained by NASA’s Kepler space telescope, a team of volunteers from the ‘Planet Hunters’ citizen science project, have discovered a distant exoplanet,named PH3c, which exhibits a highly irregular orbital period around its host star.

Astronomers Discover First Ice Giant Exoplanet Candidate in Long-Period Orbit

This artist’s concept shows Kepler-421b, a Uranus-sized transiting exoplanet with the longest known year, circling its star once every 704 days. Kepler-421b orbits an orange, K-type star that is cooler and dimmer than our Sun and is located about 1,000 light-years from Earth in the constellation Lyra.

Astronomers on Monday made a “big” announcement about exoplanets, and it is big—literally. Another new world has been discovered, which is quite routine now these days, but this one is different, and unexpected: a planet which is more than twice as large […]

There was more exciting exoplanet news this week from the Kepler mission: the space telescope has confirmed 715 new exoplanets! This brings the current total number of such worlds to 1,766, of which 961 have been found by Kepler. There are […]

PLATO Exoplanet Mission Proposal Awaits Final Selection by ESA, Following Recent Positive Recommendation

The European Space Agency’s PLATO mission aims to discover and characterize hundreds of Earth-sized exoplanets inside the habitable zones of approximately 1 million stars. The mission is likely to be approved for implementation by ESA during an announcement due for next week. Image Credit: PLATO Definition Study Report/ESA
